Fuel Pump Module Control Circuit/Open
The P025A code indicates a problem in the electrical circuit that controls the fuel pump module. This circuit includes the wiring, connectors, and the fuel pump control module itself. When the powertrain control module (PCM) detects an open or malfunction in this circuit, it sets this code. This can lead to insufficient fuel delivery, causing drivability issues.
01. Most Common Causes
- Open or shorted wiring in the fuel pump control circuit
- Faulty fuel pump control module
- Corroded or damaged connectors
- Blown fuse or relay
02. Symptoms You Will Notice
- Engine cranks but does not start
- Engine stalls or hesitates during acceleration
- Check Engine Light illuminated
- Reduced fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for additional codes and freeze frame data.
Step 2: Inspect the fuel pump fuse and relay; replace if blown.
Step 3: Visually check wiring and connectors for damage, corrosion, or loose connections.
Step 4: Test the fuel pump control module and circuit continuity with a multimeter.
Step 5: If circuit is intact, replace the fuel pump control module.
