P008E
Fuel Cooler Pump Control Circuit High
Fuel delivery
Generic OBD-II
High
What it means
P008E means the engine computer detected an abnormally high voltage in the fuel cooler pump control circuit β usually a short to voltage, an open, or a failed pump. The fuel cooler pump helps keep returning fuel from overheating, so the engine keeps running normally, but fuel can run warmer than intended until the circuit is repaired.
High
Can I keep driving? Usually drivable β the engine runs normally; the main risk is fuel running warmer than intended over long, hard driving until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Fuel cooler pump not running when it should
- Fuel temperature higher than expected during sustained load
- Often no noticeable driving symptom beyond the light
Common causes
Most likely first
- Short to voltage or open in the fuel cooler pump control circuitLikely
- Failed fuel cooler pumpCommon
- Damaged, loose, or corroded connector at the pumpCommon
- Chafed or pinched wiring pulling the control signal highLess often
- Faulty engine/powertrain control module β rareLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame data and confirm the fuel cooler pump command state.
- Inspect the pump connector and wiring for a short to voltage or damage.
- Check the pump's control and ground circuits and measure its resistance against spec.
- Repair shorted or chafed wiring and clean corroded terminals.
- Replace the pump if it fails testing; consider the control module last. Clear and re-test.
FAQ
Quick answers
Is it safe to drive with P008E?+
Usually yes. The engine runs normally; the concern is reduced fuel cooling, which mainly matters under long, heavy loads. Repair it when convenient.
Can I just clear P008E?+
It's an electrical circuit fault, so clearing it is temporary β it returns until the wiring, connector, or pump is fixed.
