P0612

DTC P0612, sometimes indicated as P061200 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the causing fuel injector control module relay control.

This code is set when the PCM detects that the fuel injector control module relay is not turning on and off as commanded. This may be caused by a wiring issue, a bad fuel injector control module relay, or a bad PCM.
If this code is being set, first check the wiring for any issues. If everything looks good, then replace the fuel injector control module relay. If the code persists, then replace the PCM.
