Engine Check light


Take it to autozone or another place like it and have them read the codes and tell us what they are.

Flashing service engine soon light flashes then shut off


Check engine lights have been used for over 30 years and yet most people do not know what they are used for.
The check engine light tells the driver a problem exists with the performance or emissions of the engine. Not the actual engine itself.
Anytime something happens that could affect emissions or performance, the light comes on and a trouble code is set in the computer memory. The driver then has to have the computer scanned for those codes to know what component to have checked.

My check engine light is on and I smell gas. 2005 chev. Suburban


Ok, the first thing to do is to have someone check the computer for trouble codes. The light is telling you there is a problem with the engine or emission system.

Check Engine Light Flashing Rough Idle, gas smell and lack of power


Hi Marlene:
When the light comes on, one or more diagnostic trouble codes (DTC) are stored in the engine control module. These DTCs remain even if the light goes out. To address a Check Engine Light problem, the DTCs are retrieved and the appropriate troubleshooting information is followed in order to determine the problem.

The Four Most Common Check Engine Light Scenarios and What to Do:
* The Check Engine Light turns on and off or flickers.
If the Check Engine Light comes on in the city but goes off on the freeway, then the fault is present during city driving conditions. Pay attention to whether or not the vehicle runs or drives any differently when the Check Engine Light illuminates. If vehicle performance does change, drive the car as little as possible and take it to be checked by a service professional as soon as possible. If there is no change in vehicle performance, you can drive home, but have it inspected as soon as possible. In this condition, you run a risk of the vehicle dying or not starting.

* The Check Engine Light comes on and stays on.
If the Check Engine Light illuminates constantly during driving with no noticeable driving or performance problems, there is a permanent fault in the emission control system. When this happens, the computer that controls the emission system usually has a backup program that runs while the fault is present. (These backup programs are often referred to as "limp home" mode programs.) You should get the vehicle serviced as soon as possible, but in most cases, the vehicle will continue to operate, though you run a risk of it dying or not starting.

* The Check Engine Light illuminates, stays on, and there are performance problems.
This means that a vital component of your emission control and engine management system has a serious problem. It usually involves a component or system needed for the vehicle to run at all. In most cases, drive the vehicle as little as possible. In many cases, the vehicle is not safe to drive at all -it could stop or stall out at any moment. It is best to pull over to a safe place and have the vehicle towed to an automotive diagnostician for a thorough inspection and repair.

* The Check Engine Light light comes on and blinks in a steady pattern while driving.
Don't confuse this steady pulsing of the Check Engine Light light (usually one or more flashes per second) with a flicker (see above). The Check Engine Light may stay on steadily or it may flash when the vehicle is accelerated. This is very serious. There is a severe failure of the emission control system that is causing the engine to misfire to the point that the catalytic converter is damaged each time the Check Engine Light flashes. It may mean that the catalytic converter is overheating to the point that it will glow red or, in extreme cases, start a fire on the underside of the vehicle. Immediately pull over to a safe place and have your vehicle towed to an automotive diagnostician for repair. Vehicles can be severely damaged and even destroyed by fire if this condition is ignored for too long.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

The "Service Engine Soon" light


These are both EVAP emissions codes. The first thing I would do is open the fuel door and take a good wiff. If you smell gas replace the fuel cap.

If you don't smell gas the next thing you can do is visually inspect all the EVAP hoses and lines for cracks or holes. The EVAP system consists of a purge solenoid, a charcoal canister, a vent solenoid, a fuel tank pressure sensor, and misc. lines and hoses. All of these will need to be visually checked for damage.

If you don't see anything with a visual check than the next step would be to have the EVAP system smoke checked for leaks. A smoke machine will be used to slightly pressurize the EVAP system with smoke. Where ever the smoke comes out is where is is leaking.

Engine light on and engine sluggish with a smell


The check engine light/service engine soon (yellow light) comes only when the computer control unit (called the PCM) senses a fault in the electronic controls of the engine and/or the emission system u will seldom feel the car engine run any different, there are about 200 possible faults that turn the light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen and Autozone parts stores do this testing for free.

1998 nissan altima dashboard display engine service soon


Hello and thank you for using FixYa!

The service engine soon light comes on when a fault is detected in the emission system. The service engine soon light is the same thing as a check engine light. A scan tool will be needed to get the code for the failure, so the proper repairs can be made.

Thanks Jay!

Engine light on, heavy smoke and engine burning smell (Audi 1.8T)


First off, how the Hell did they issue a DOT Cetificate, if the Emissions are known to be off the clock. Without causing stress, do you have, or can obtain the Emission Test Result Print Out from the Testing Station test Equipment. This is something they cannot refuse. DO NOT AUTHORISE ANY REPAIRS Come back TO ME with your story.
