P025C

Fuel Pump Module A Control Circuit Low

Q: Is it safe to drive with P025C?

No — the pump may cut out and strand you. Have the circuit diagnosed before driving.

Q: Can I just clear P025C?

Clearing won't repair the circuit; the code returns and the car may not start until the fault is fixed.

Fuel delivery Generic OBD-II High

What it means

P025C means the ECM sees a low-voltage (shorted or open) fault in the control circuit for the "A" fuel pump module — the electronics that drive the fuel pump. Because it directly affects fuel delivery, the car may crank without starting, stall, or run rough. Start with the fuse, relay, and control wiring before condemning the pump module.

High

Can I keep driving? Risky — a low control-circuit fault to the fuel pump module can cause stalling or a no-start, so treat it as leave-it-parked until diagnosed.

How to diagnose & fix

Work through it in order

Scan and read freeze-frame data, then confirm the circuit is reading low (shorted or open).
Check the fuel pump fuse and relay first — the cheap, common failures.
Inspect the control-circuit wiring and connector for shorts, chafing, and corrosion.
Measure control voltage at the fuel pump module during key-on and cranking.
If wiring and power are good, replace the fuel pump control module. Clear and re-test.
