It will only go off itself if the computer detects no errors. You probably have an issue that keeps the light on. It can be reset with a scanner hooked up, but it will only come back on.

The On Board Diagnostic (OBD) system that turns on the check engine light when something wrong is detected. When that problem is fixed, the OBD will check all for a predetermined amount of trips and then it should turn off the light when all is well again. I hope this helps.

Is there a reset button for check engine light


You must use a code reader to turn off the check engine light. Just because you are not having drive ability issues doesnt mean there is nothing wrong. Chances are that check engine light is on for a reason.

The check engine light is telling you there is a problem and there are trouble codes stored. Have someone scan it or check it for codes yourself.

How do you reset the "check engine light" and the


The maintenance lights rest by holding down the speedometer reset button and then turning on the key. Hold button for 15 second after ignition is on. Light will go out.
The check engine light may be another matter. If it does on also go out with the above procedure, you may have computer fault codes that need to be addressed.

How to reset low pressure light after having new tires installed


Though all of these TPMS applications use a similar technology and strategy to detect a low tire, there is no common reset procedure. GM is probably the worst, with 10 different reset procedures depending on the application. Toyota is probably the best, with only one simple reset procedure for all of their indirect TPMS systems (though a slightly different procedure is used on the Lexus models).

TPMS reset procedures may also be found in the vehicle owner’s manual (if it hasn’t been lost). Open the glove box and check the index in the owner’s manual for any TPMS information.

CHEVY IMPALA &
MONTE CARLO

On a Chevy Impala or Monte Carlo with indirect TPMS, a totally different reset procedure is required. You can use the light switch or radio to reset the system. With the light switch procedure, turn the ignition on (engine off), the turn the light switch from OFF to parking lamps three times within five seconds. With the radio technique, turn the ignition on (engine off). With the radio off, hold the DISP button until “SETTINGS” is displayed. Use the SEEK button to scroll down the menu until you see “TIRE MON.” Press the PREV or NEXT buttons until “RESET” is displayed. Then press the DISP button again. You should hear a chime and see “DONE” to indicate the TPMS system has been successfully reset. Use the SEEK button to scroll through the menu until “DONE” is shown, then press DISP once more to exit from the learn mode.

Good luck and this should work for you. They changed the reset procedure on the 2006 Impala.

Reset check engine light


First of all, you should'nt do this unless you know what the problem is.. or what tripped it. I had this problem when my husband and I were replacing a head unit and disconnected the old head unit, a/c and other stuff then turn the car on. This made the light flash. The first time we took it in and got charged $50 to reset it. The second time we did this procedure and it worked.

ECU Resetting Procedures

Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON.
A stop watch or an analog clock with a second’s needle will be useful.

Reset Check Engine Light Procedures

1. Confirm that accelerator pedal is fully released, turn ignition switch “ON” and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 seconds.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to “OFF” position and now you can start the car. The CEL light should be gone.

If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.
