P008E: Fuel cooler pump control — electrical signal high — what it means, the affected system and what to check before replacing parts.
Meaning, symptoms, causes and checks
The monitor identifies a high electrical condition in the fuel-cooler-pump control circuit. This is a circuit-level description, not a statement that fuel temperature or pump output is physically high. Ford includes the code in its published diagnostic list; vehicle-specific circuitry is needed to distinguish wiring, driver and pump-related faults.
Affected system: Fuel cooler pump control
Symptoms
- Warning light may illuminate
- Related system function may be impaired
- Vehicle-specific symptoms vary
Possible causes
- Fuel supply or pressure issue, restricted injector, actuator fault, connector or wiring damage
- Related wiring, connector, power or ground fault
- Vehicle-specific mechanical or control issue
What to check
- Record stored and pending codes and freeze-frame data
- Check fuel supply and pressure readings, electrical supply and ground, and the relevant injector or regulator circuit before replacing parts.
- Confirm measured values against the vehicle service information
- Retest under the conditions that set the code
- Check fuel supply and pressure readings, electrical supply and ground, and the relevant injector or regulator circuit before replacing parts.
- Repair the verified cause and confirm the code does not return
Also written as: P008E-00, P008E00, PO08E (some scan tools add the fault-type byte, e.g. -00).
