P025A Code: Meaning, Causes, and Symptoms | OBD2 Codes
P025A – Fuel Pump Module Control Circuit/Open
P025A Possible Symptoms
Engine Light ON (or Service Engine Soon Warning Light)
P025A Possible Causes
Faulty Fuel Pump Command (FPC),FPC Harness is open or shorted,FPC circuit poor electrical connection
The Powertrain Control Module (PCM) monitors the Fuel Pump Command (FPC) circuit for a concern. When the PCM commands the Fuel Pump (FP) ON, the PCM is able to detect a short to voltage on the FPC circuit. When the PCM commands the FP OFF, the PCM is able to detect an open circuit or a short to ground on the FPC circuit. The test fails if the voltage is less than or greater than a calibrated limit, for a calibrated amount of time.
