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.

What is service engine light code 12 mean



READING CODES USING MIL (CHECK ENGINE) LAMP

Be advised that the MIL or CHECK ENGINE light can only perform a limited number of functions and it is a good idea to have the system checked with a scan tool to double check the circuit function.

  1. Within a period of 5 seconds, cycle the ignition key ON - OFF - ON - OFF - ON .
  2. Count the number of times the MIL (check engine lamp) on the instrument panel flashes on and off.

The number of flashes represents the trouble code. There is a short pause between the flashes representing the 1st and 2nd digits of the code. Longer pauses are used to separate individual 2-digit trouble codes.
An example of a flashed DTC is as follows:


Lamp flashes 4 times, pauses, then flashes 6 more times. This denotes a DTC number 46. Lamp flashes 5 times, pauses, then flashes 5 more times. This indicates a DTC number 55. DTC 55 will always be the last code to be displayed.

Check engine light indicates p700 code


Diagnostic Test Code (DTC) P0700 is an informational code that is stored in the Engine Control Module (ECM) That informs the diagnostic technician that there are codes present in the Transmission Control Module (TCM) and that the TCM has requested the Malfunction Indicator Lamp (MIL) (AKA - Check Engine Light) to be turned on. This is because the MIL is controlled by the ECM and cannot be turned on directly by the TCM. So, the TCM requests the ECM to turn the light on. To find out the nature of the failure that caused the P0700, one must scan the TCM to retrieve the fault codes stored there. Please note that MOST generic OBD code readers cannot access the TCM - this is the reason for the P0700 code to set in the ECM (to alert somebody with a generic code reader that further diagnosis is needed for the TCM).

Mil comes on and has a code of p442. what does that mean


It means you have a leak in the EVAP system. Most likely the hoses near the charcoal canister. Check the EVAP hoses for cracks, and replace as necessary.

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
