Ford OBD II Powertrain Diagnostic Trouble Codes P1500-P1699

Copyright Trouble-Codes.com


Diagnostic Trouble Code numbers are read by plugging a code reader or scan tool into the vehicle diagnostic connector (usually located under the instrument panel near the steering column) that can read vehicle manufacturer enhanced or P1 c odes (not just generic or P0 codes). The presence of a code will turn on the Check Engine Light. The light will remain on until the code has been erased. The code number does not tell you which part has failed. It only indicates a possible fault has been detected in the circuit, system or sensor described. Further testing is usually required to isolate the fault BEFORE repairs are made.

For vehicle specific diagnostic charts and vehicle specific repair information, refer to a service manual, or get a subscription to the Ford Motorcraft Tech Info website, or AllDataDIY.


The following is a partial listing of common Ford specific "P1" enhanced OBD II fault codes:
