P025B

Fuel Pump Module A Control Circuit Range/Performance

Q: Is it safe to drive with P025B?

Not really. The fuel-pump control circuit is performing out of range, so the pump may drop out and cause stalling or a no-start. Get it diagnosed before depending on the car.

Q: Can I just clear P025B?

It will return whenever the circuit performs abnormally again. Repair the module, wiring, or pump rather than clearing it.

Fuel delivery Generic OBD-II High

What it means

P025B means the ECM sees the fuel-pump (driver) module's control circuit performing outside its expected range — the commanded and actual pump behavior don't match. Because this circuit governs how the fuel pump is driven, delivery can become unstable, leading to hard starting, stalling, or a no-start. Check the fuse, relay, wiring, and grounds before replacing the module or pump.

High

Can I keep driving? Risky — fuel delivery can become unstable, causing stalling or a no-start, so treat it as urgent and avoid long trips until fixed.

How to diagnose & fix

Work through it in order

Read freeze-frame data and check the fuel-pump fuse and relay.
Inspect the fuel-pump module connector, wiring, and ground.
Monitor fuel pressure and the pump-control signal with a scan tool.
Replace the fuel-pump driver module or the pump if it is faulty.
Clear the code and re-test.
