P1237 - Fuel Pump Secondary Circuit Fault
- Fuel Pump Driver Module (FPDM) harness is open or shorted
- Fuel Pump Driver Module (FPDM) circuit poor electrical connection
- Faulty fuel pump
Fuel Pump Driver Modules (FPDM) controls the voltage to the Fuel Pump in order to maintain proper fuel pressure over the full operating range of the engine. The P1237 code indicates the FPDM detected a fuel pump secondary circuit concern. The FPDM sends a message to the Powertrain Control Module (PCM) through the Fuel Pump Monitor (FPM) circuit indicating this concern was detected. The PCM sets the DTC when the message is received.
