Duke Is Beginning to See the Light (Check Engine Light Diagnostics)

duke

Good Day, Duke here and you know we have all heard and maybe said the famous quote, "I'm beginning to see the light." but today, we really are dealing with seeing the light in our vehicle, the Check Engine Light.  So let's start barkin' and venture into the unknown of the Check Engine Light!

It's a light many drivers fear they'll see turn on at the most inopportune time.  It's the one on the dash that says "Check Engine," "Service Engine Soon," or it may be simply an engine-shaped light. Your first instinct may be to pull off to the side of the road and turn off the engine.

The truth is that the Check Engine light can be pointing to problems as simple as a loose gas cap. But it could be as serious as a severely misfiring engine.  Don't ignore it because it's there to help you avoid an expensive repair. It is designed to alert you, to tell you something's not quite right.

Your vehicle has a connected system of computers and sensors constantly checking to see that all systems are working the way they should. If something isn't, the system will turn on the Check Engine light.

If it's flashing, that could be serious. Look at some of the other warning lights or gauges, such as heat or oil pressure. They could be telling you your vehicle's problem should be checked right away. In that case, if you can, safely pull off the road and shut the vehicle down. If your vehicle loses power and the Check Engine light is on, try not to push the demands you are making on the engine, such as towing or accelerating hard.

Simply put, a flashing Check Engine light should be checked out by a professional as soon as possible.

If the Check Engine light is on steadily, manufacturers say it means there's a problem, but it probably doesn't require immediate service.  The system is designed to remember the problem it found and store it (as a code) so it can be retrieved later.

When you do bring your vehicle in to have us see what's behind the Check Engine light coming on, we’ll hook your vehicle up to a diagnostics tool that can reveal the clues the engine's computers have stored.  It takes a trained technician to understand those clues, like a doctor who can interpret a patient's symptoms and come up with the correct diagnosis. Some newer vehicles can even be checked remotely.

Once we figure out the problem and repair it, you'll be back on the road again. It's nice to know the Check Engine light is your sentry, standing by to alert you the next time you begin to "see the light."

"I never cared much for moonlit skies

I never wink back at fireflies

But now that the stars are in your eyes

I'm beginning to see the light" ~Ella Fitzgerald

Cayenne's Advice On The Light Many Drivers Fear (Check Engine Light)

cay

What do you fear?   I fear running out of bones. Hi Cayenne here and we all fear something, even with our vehicles.  Ask just about any driver about one thing they fear seeing inside their vehicle and they'll say it's the Check Engine light coming on. You know, that little light on your instrument panel that is in the shape of a vehicle engine, often accompanied by the words Check, Check Engine, Check Engine Service, or Service Engine Soon.  So yes, today, we will take the fear out of the Check Engine Light.  Let's get barkin'!

There are so many different reasons that light shows up, from something as simple as a loose gas cap to a more serious problem that requires immediate attention. 

The Check Engine light comes on because a component of your vehicle's onboard diagnostics system is telling you something isn't operating normally. Your vehicle has a lot of sensors built in, all tied together by computers.  When the sensors are showing that things somewhere aren't functioning the way they should be, they alert the vehicle's diagnostic computers and tell you something's amiss.

The simple rule is if the Check Engine light is on steadily, it's something you should have checked soon but it's not urgent.  If it's flashing or has turned red or orange instead of yellow, get your vehicle checked out as soon as possible.  If you don't, you may be facing some costly repairs.

Here are a few problem areas that may trigger your Check Engine Light. 

  • Something's wrong with the emissions equipment.  Maybe too much fuel is getting into the catalytic converter, or the exhaust gas recirculation system isn't working right.  Because some of these components are expensive to replace, it's worthwhile to have a technician look at your vehicle sooner rather than later.
  • Your ignition system isn't working right.  That means spark plugs, coils, and wires.  If your engine is misfiring, that could translate into an illuminated Check Engine light.
  • The transmission isn't behaving the way it should.  The transmission works in tandem with the engine, so if a sensor sees something wrong there, it will tell the vehicle to turn on the Check Engine light.

As you can see, there are many things that can cause the light to come on, and when it does, it really is a good idea to find out why.  When you bring your vehicle in, we have an electronic device that can read a code or multiple codes stored in your vehicle's computers.  That will provide the technician with clues pointing to the cause of the trouble and helps pinpoint where that trouble is. 

I leave you with this thought,

Fear makes the wolf bigger than he is. ~German proverb

Duke's Fuel Saving Tip: Check Engine Light

duke

Hey Duke here and here's a question for you : How long have you been enjoying the romantic glow of your Check Engine light? 

Hey, it's not there to create ambiance; it's a warning that something's wrong. (And, by the way, Homer Simpson's fix of covering it with tape is not a good idea.)

Many conditions that trigger the Check Engine light can hurt your vehicle. A lot.

If your date's eyes are smoldering in the soft glow of the Check Engine light, try to think of all the gas money you'll save by getting it fixed. Give Allied Auto Works a call when you are ready and tell them Duke sent ya.

Cayenne's Advice On Things Aren't Always What They Seem

cay

Hi Cayenne here and you have heard the old saying, "Things aren't always what they seem."  This happens to me all the time when I walk into my master's bedroom and the nightlight casts a shadow on the wall.  I look like this large Direwolf walking into the bedroom but it is just little old me.  If the same with your vehicle. If you drive, you know at some point, something's going to go wrong with your vehicle.  And sometimes, it's pretty easy to figure out what's wrong, like a flat tire.  But sometimes your vehicle's symptoms can be really puzzling.  So today we will bark about what we think see or hear and what we need or should do.  Let's get barkin'!

One driver in CA was heading to work on a hot July day and noticed when he pressed the accelerator, sometimes it wouldn't do anything. He also noticed his cruise control wouldn't work and his traction control light was constantly on, very unusual.

He was trying to figure it out, but none of it made any sense.  His cruise control had always worked perfectly, his traction light never had gone on before and there was never any issue pressing on the accelerator.

It was time to take his car in for a professional diagnosis, and boy, was he surprised that it was a freak accident he'd had the previous WINTER that was the root of his problems.  You see, in January, his car had slipped on ice when he was in reverse and had gently tapped a tree.  That caused a tiny crack in his rear stoplight. 

That crack had gone unnoticed until that July day.  Turns out a summer rain allowed water to seep into the taillight casing, so this time when he drove to work, there was enough moisture inside it to cause his stop light to stick on.

When the stoplight is on, the car's computer is programmed to act as if the driver is pressing the brakes. It also disables the cruise, accelerator, and cruise control when the brakes are on, producing all of the symptoms.  Replacing the stop lamp switch fixed everything.

So, while some things that go wrong with your vehicle are pretty obvious, many seemingly defy all logic. That's when a trained technician can scope things out, replace the right part and get you going again.

Duke's Serious Note: Dashboard's a Funny Name (Instrumental Panel Warning Lights)

dukeI have my serious hat on today, hey it is Duke, and today we are going to bark about something funny well not really funny but the name is DASHBOARD or a more serious name Instrumental Panel Warning Lights.  This all sounds silly to me but what do I know, I just a dog with a hat on.  Let's get started!

Every day you drive, you're sitting behind the dashboard. But how in the world did it get that name? Back in the days of the horse-drawn carriage, horses would kick up dirt and mud on the driver and passengers, "dashing" debris against the carriage. So those who built carriages began installing a board to protect them. So, dash-board. Dashboard.

The dashboard is still there, though changed quite a bit from the early days. Now its main purpose is to house the controls and instruments for your vehicle's systems.

Of course, you have the speedometer, tachometer and gas gauge. But there are four warning lights you need to pay attention to on your dashboard and instrument panel. Some of these may even be gauges, depending on your model of vehicle. Regardless, paying attention to them is a good idea if you want your vehicle to keep going as long as possible.

Oil pressure—The oil pressure light will come on if your engine doesn't have enough pressure in its system. Low oil pressure means engine parts aren't getting lubricated properly. This can cause really serious damage and do it quickly. If your oil light goes on, call your Allied Auto Works service advisor immediately if you can. Even driving a short distance may ruin your engine.

Check Engine light—If a light that looks like an engine comes on, it's not necessarily signaling a catastrophe. But it means one or more sensors in your vehicle have detected an abnormal situation. Have your vehicle checked soon. There will be a code stored in your vehicle that a technician can read and use it as an extra clue as to what's going on.

Brake light—If this lights up, first check if your parking brake is on. If it isn't, you could have serious brake issues. It's a sign you should get the brakes checked soon at Allied Auto Works.

Tire pressure—Tire pressure monitors are built in to newer vehicles. They let you know if any of your tires are over or underinflated. Both conditions need to be checked out. That could prevent a blowout or premature tire wear.

The dashboard isn't what it used to be. In fact, it's much better now… and much more informative. Take advantage of that information and keep your vehicle running the way it's meant to.

 

NOW THIS SILLY, what a nose

Cayenne's Check Engine Light Diagnosis At Allied Auto Works

cayenne

Hello it's Cayene to all of my  Los Altos car owners. Have you ever had your check engine light come on? Did you panic? Or just scowl and ignore it? What should you do? Pull to the side of the road and call a tow truck? Or just keep driving? What does that little light really mean for Los Altos auto owners?

First of all, the Check Engine or Service Engine light does indicate that something is wrong. That’s why it is called a warning light. But the something that is wrong might be a loose gas cap, or it might be serious sedan engine trouble. That’s why Los Altos drivers often don’t know how to respond to it.

The check engine light has two modes: it flashes or it stays on. A flashing light is serious. You need to get your vehicle to Allied Auto Works in Los Altos ASAP. No, you don’t need to call a tow truck, but, yes, you can’t wait to get your car serviced. If your check engine light is on and flashing, you should not tow trailers, haul heavy loads or drive at CA interstate speeds. Any of these could lead to serious damage that could result expensive repair bills for Los Altos auto owners who ignore it.

A steady check engine light is less serious, but that doesn’t mean it can be ignored by Mt. View motorists. You should plan to get your vehicle inspected at your local Los Altos automotive service center the first realistic opportunity. Not the first convenient opportunity, but the first realistic one.

Before you take your sedan in, however, check the gas cap. A loose gas cap can trigger the check engine light. If it is loose, twist it until it clicks three times. If that was the problem, your Los Altos engine light will reset after several days. However, if it stays on, then you need to schedule an inspection at your Los Altos auto repair center center or Allied Auto Works.

Modern automobiles have a computer in the engine that monitors and controls many of the engine functions. When the computer senses something wrong, it first tries to fix the problem itself by adjusting the sedan engine. If the problem persists, the computer signals the check engine light to come on.

This process stores a trouble code inside the sedan engine’s computer. Your service specialist scans the computer and reads the code. This does not tell the service advisor exactly what is wrong with the car, but it gives him a good idea as to where to start looking.

It is NOT good auto advice to deal with a check engine light by disconnecting the battery. Yes, this makes the light go off, but it doesn’t solve the problem. It’s rather like trying to put out a fire by disconnecting the smoke detector. Also, disconnecting the battery will erase your sedan’s computer memory. An engine’s computer, over time, learns to adjust for peculiarities of the specific sedan engine, for driving conditions in your Sunnyvale area, and for your driving habits. Losing its memory means it has to learn and adjust for these things all over again.

Also, don’t buy a cheap consumer scanner or get a trouble code read at your nearest Los Altos auto parts store, then try to fix a problem yourself — unless, of course, you are a trained Los Altos mechanic. Today’s auto repair equipment is fairly high-tech and knowing a code is only an indication of where a problem might be, not the answer to what is wrong. Trying to save a little money by doing it yourself may end up costing you big in the long run.

Of course, the best thing to do is to keep that pesky check engine light from coming on in the first place. Good car care and routine preventive maintenance go a long way to keeping your sedan out of your Los Altos auto repair shop. But, if that light does come on, be smart. Take care of the problem early, and take care of it professionally.
