P025A

Fuel Pump Module A Control Circuit/Open

Fuel delivery Generic OBD-II High

What it means

P025A means the ECM detected an open in the control circuit for fuel pump module 'A', the driver that runs the electric fuel pump. Because this circuit governs fuel delivery, a fault can cut or reduce fuel pressure — leading to hard starting, stalling, or a no-start — so it's one of the more serious fuel-system circuit codes.

High

Can I keep driving? Risky — this circuit controls fuel delivery, so it can cause stalling, hard starting, or a no-start. Address it before relying on the vehicle.

Stalling or hesitation, especially under load
Rough running from low or lost fuel pressure

Common causes

Most likely first

Open circuit in the fuel pump module 'A' control wiring or connectorLikely
Blown fuel pump fuse or failed relayCommon
Failed fuel pump (driver) moduleCommon
Corroded or loose terminals in the control circuitLess often
Faulty ECM control driver (least likely)Less often

How to diagnose & fix

Work through it in order

Read freeze-frame data and check the fuel pump fuse and relay first.
Inspect the fuel pump module connector and control wiring for an open circuit or corrosion.
Verify the ECM's command signal reaches the module and the module drives the pump.
Test fuel pressure to confirm delivery; replace the fuel pump module if commanded but not responding.
Repair open wiring, then clear the code and re-test starting and driving.

FAQ

Quick answers

Is it safe to drive with P025A?+

Not reliably. Because this circuit controls the fuel pump, it can cause stalling or leave you unable to restart. Fix it before depending on the car.

Can I just clear P025A?+

Clearing it won't restore fuel delivery — it returns immediately if the control circuit is open. Repair the wiring, fuse, relay, or module first.
