OBDII Codes

Filed under: Auto Diagnosis,Auto Repair @ 10:52 am

You receive an OBDII Diagnostic Trouble Code when the Check Engine Light ignites. Read more about how the Check Engine Light works.

Common OBDII Diagnostic Trouble Codes (DTC):
P0100    Mass or Volume Airflow Circuit Error
P0200    Injector Circuit Error
P0300    Engine Misfire Detected
P0400    Exhaust Gas Recirculation (EGR) Error
P0500    Vehicle Speed Sensor Error
P0600    Serial Communication Link Error
P0700    Transmission Control System Error/Request for MIL

Commonly occurring OBDII Codes
NOTE:

- a “0″  in the second position indicates a generic industry standard code
- a “1″ in the second position indicates the code is manufacturer specific and requires access to a database for a more detailed description
- Every AAMCO Center has access to manufacturer databases.

  1. I have a 2007 Chrysler 300 6 cylinder auto with the engine light on (not flashing). When I click on the ignition quickly on and off three times the odometer goes from showing my mileage to the number 1004. What does this indicate?

  2. Can you tell me what a P code of 1004 means?

  4. The code is for “short runner valve control performance”. According to Alldata, there are several steps that we would need to go through to determine the actual problem. It could be a wiring problem or even a faulty Transmission Control Module (TCM). I would recommend a complete electrical diagnostic test.

  5. The check engine light is on because it is storing a code or codes. We would need to hook up a scanner that would read the codes and then clear the codes with the scanner. Any AAMCO Center would be glad to do that at no cost to you. But, unless the source of the codes is repaired or replaced, the check engine light will come back on.
