P0232

Fuel Pump Secondary Circuit High

DTC P0232, sometimes indicated as P023200 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 air/fuel mixture causing fuel pump secondary circuit high.

This code is set when the PCM detects that the fuel pump secondary circuit has high resistance or an open circuit. This can be caused by a number of things, including a bad fuel pump, a bad fuel pump relay, a bad wiring harness, or a bad PCM.
If this code is set, first check the fuel pump for proper operation. If the pump is not working, replace it. If the pump is working, check the fuel pump relay and wiring harness for damage or faults. If the relay or wiring harness is bad, replace them. If the PCM is bad, replace it.
