P062A
Fuel Pump A Control Circuit Range/Performance
Fuel pump control
Generic OBD-II
High
What it means
P062A means the engine computer's fuel pump control circuit is not performing as expected — the pump's commanded and actual behavior don't match. Because this circuit governs fuel delivery, symptoms can range from hard starting and hesitation to stalling or a no-start. Check fuel pressure and the pump control wiring first.
High
Can I keep driving? May stall or fail to start — this circuit controls fuel delivery, so a fault can cause stalling, hard starting, or a no-start; repair it promptly.
Common symptoms
What you'll notice
- Check-engine light on
- Hard starting or extended cranking
- Stalling or hesitation, especially under load
- Long-crank or no-start in some cases
Common causes
Most likely first
- Faulty fuel pump or fuel pump driver moduleLikely
- Open or shorted wiring in the fuel pump control circuitCommon
- Poor connection or corrosion at the pump or relay connectorCommon
- Faulty fuel pump relayLess often
- Failed engine control module (rare)Less often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and check actual fuel pressure against spec to confirm whether delivery is affected.
- Inspect the fuel pump control wiring and connectors for opens, shorts, and corrosion.
- Test the fuel pump relay and, where fitted, the fuel pump control/driver module.
- Verify the ECM is commanding the pump correctly; if the command is present but performance is out of range, test and replace the pump. Clear the code and re-test.
FAQ
Quick answers
Is it safe to drive with P062A?+
Be cautious. Because this affects the fuel pump control circuit, the engine can stall or refuse to restart. If it's running rough or hard to start, get it looked at before driving far.
Can I just clear P062A?+
Clearing it won't restore proper fuel delivery, and the stall/no-start risk remains until the pump, relay, or wiring is repaired.
