I am assuming you are talking about the 'check engine' or 'service engine' light, right? Well, they can cut the light out by clearing your car's computer memory, but it came on for a reason in the first place. So, if they didn't fix the problem, guess what? You will get the light on again. I think they know this too. I would say the dealer would have to be pretty brave to NOT fix whatever the problem was. By retrieiving the trouble code on your vehicle's on board computer, they can easily go right to the system on your vehicle that is experiencing a problem. It's not like it is that hard to trouble shoot a vehicle with an on board computer since they have specially trained mechanics for your particular vehicle make. I would say you could trust their work if the light didn't come on after driving away and they could give you a detailed description of what the problem was. But as a consumer, remember you do have the right to ask and if they say they are going to or did replace a part, make sure you let them know you are going to want to see the old part or have them point out the new part to you when you pick up your vehicle.
dealer has them for 800 and something. Lighting control module
You check engine light is signaling to you that there is something wrong with you car. You should have your car looked at by a professional.
Drive it to the mechanic. You have something wrong and that is what the car is telling you. Oil, water, something is not right.
It depends...Some faults turn on the Check engine light and some dont. You will need to get the car scanned to be certain that there are no fault codes.
it resets every time you turn your car on. i have a 01 eclipse and the dealer told me that.
the engine light stays on. Hyundai dealer wants 241 plus to install and fix. Does using car with engine light on do damage?
The check engine light means that there is something not going right with the engine, but it may not be serious. Take it to Auto Zone or a small shop with the capability to read out the ODBII codes rather than go to the dealer. They'll plug it in and be able to tell you what error triggered the check engine light. I've had my light come on twice, neither time was it a serious problem. The first time was due to bad fuel, the second a minor electrical short in the air intake temperature sensor.
Yeah, it can. If something is wrong with your emmision control system, your car can still fail emmisons, but the check engine light doesn't have to be on.
engine has defaulted to limp home mode... (engine fail safe mode) get to a dealer or mechanic as soon as possible
The best thing to do is go to your dealer or ask a mechanic. I ride a motorcycle and do not own a car so I can't help you much with this.
You will have to ask to a car dealer first the car specifications and also if the car has some defective parts especially the engine or not and the price too.
Engine sludge is what the dealer told me Engine sludge is what the dealer told me
Something is wrong if the check engine light is on. If the engine is running great then there is no great hurry to get it fixed but there is something wrong with the emissions system or the light would not be on. It is your choice to fix it or not. It may never cause any problems and it could damage the O2 sensors or the converter depending on what is wrong.
It means that your car is due for maintenance such as an oil change. It's more of a "reminder" than a warning that something is horribly wrong. If something was mechanically wrong with your car the actual "Check Engine" LIGHT would be on. Hope that helps!
If the check engine lights are on, that means that there is something wrong. A mechanic can check and tell what is wrong with the car.
Many reasons! Go to the Dealer or Auto Zone (free) and have your problem codes read from the computer in the car.
This information can be found in your owner's manual. Don't have one, get one. Dealer or salvage yard is a source.
There is something wrong with the airbag deployment system. Take the car to the Dealer.
if your car reads sensor light go to workshop if esp light is on and check engine light the car is in limp mode go by a battery put it in your self dont go to crooked dealer
The "Service Engine" light is the computer's way of telling you that it has something to tell you. Connect a scanner and see what it says.
It has something to do with the immobilizer & keyless entry system programming. Take your car to the dealer. He will have to use a special scanner and laptop PC to program.
I have a 2006 Saturn ion. The reduced engine power light came on and the car still runs but will not accelerate and only goes 30mph
well just imagine that you are building a car, or a train or an airplane and the metal you use for something starts to rust, if that's near the engine or something that leads to the engine than it could put set the car a light.
Dealer? Salvage Yard? Engine rebuilder?
