Why does check engine light blink when I accelerate?


Hi Ced ,
The malfunction indicator lamp (MIL) is located in the instrument panel cluster. The MIL will display as either SERVICE ENGINE SOON or one of the following symbols when commanded ON:
Check engine ! The MIL indicates that an emissions related fault has occurred and vehicle service is required.
The following is a list of the modes of operation for the MIL:
?€¢
The MIL illuminates when the ignition is turned ON, with the engine OFF. This is a bulb test to ensure the MIL is able to illuminate.


?€¢
The MIL turns OFF after the engine is started if a diagnostic fault is not present.


?€¢
The MIL remains illuminated after the engine is started if the control module detects a fault. A diagnostic trouble code (DTC) is stored any time the control module illuminates the MIL due to an emissions related fault. The MIL turns OFF after three consecutive ignition cycles in which a Test Passed has been reported for the diagnostic test that originally caused the MIL to illuminate.


?€¢
The MIL flashes if the control module detects a misfire condition which could damage the catalytic converter.


?€¢
When the MIL is illuminated and the engine stalls, the MIL will remain illuminated as long as the ignition is ON.


?€¢
When the MIL is not illuminated and the engine stalls, the MIL will not illuminate until the ignition is cycled OFF and then ON.

What does mil cmd fail mean?


MIL is your malfunction indicator lamp, (check engine light)

CMD is the computer interface port, or OBDII port indicating a malfunction communicating with your cars computer

check all the fuses, primarily any marked pcm and retest your vehicle
note: your check engine or MIL has to be on in KOEO state (key on engine off), if the bulb is burned out everything will still work and the OBDII test computer will show MIL status ON, and if you don't have a computer to tell you that, you must get that light to light in the koeo state.

The service engine soon light will not come for pretest before starting engine. It is an automatic fail for emissions test. 2002 gmc sierra.


This could be something as simple as the Service Engine Soon light bulb being burned out. Removing the instrument cluster isn't too terribly difficult, but if you can carefully pull it out of the dash, look behind where the bulbs are located and see if that one happens to be burned out.
I hope this helps! :)

Check Engine or
Malfunction indicator light (MIL)
The Check Engine or Service Engine Soon light or an icon resembling the engine is called, in technical terms, the Malfunction Indicator Light or MIL. The MIL light comes on when your vehicle's computer detects a fault that can affect your vehicle's fuel economy and emissions. There is no button to reset the Check Engine light, but if the fault that caused it doesn't happen again, the light will turn off by itself. If the MIL light stays on, have the problem checked out, because in some cases, the problem could get worse if not repaired in time. Think of the Check Engine light as an early warning sign. To check why your MIL light came on, your dealer or mechanic will have to diagnose your car with a special scan tool.

Got 2008 3500 dodge,was working on trailer lightsand was checking fuses and pulled wrong fuse and check engine light come on. how do i get it off?


The only way to turn off the MIL (Malfunction Indicator Light) or "check engine Light", is to either use a scanner to reset the MIL, or you can dis-connect the battery for three minutes, but if you do dis-connect the battery you will have to re-set the radio and anything else that has a KAM (Keep Alive Memory).

What does code 1-p0650 mean?


P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction

Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.

Possible Causes:
  • Harness or connectors (MIL circuit is open or shorted.)
  • MIL bulb may be faulty

    MIL Check Engine Light Stays on


    I HAVE THE SAME PROBLEM WITH MY 2002 SEDONA. I HAVE HAD IT TO SEVERAL DEALERS AND ALL HAVE THE SAME ANSWER, THEY DON'T KNOW WHAT THE PROBLEM IS. SO I JUST FORGET ABOUT IT. CHECK YOUR WINDSHIELD WASHER FLUID, ENSURE IT IS FULL, TRANSMISSION FLUID, ENGINE OIL, BRAKE AND POWER FLUID, THE NORM. IF NONE OF THIS WORKS, DON'T SPEND ALOT WORRYING ABOUT IT.
