P0E1E — Hybrid/EV battery coolant pump B control driver — driver current/temperature too high

P0E1E concerns hybrid/EV battery coolant pump B control driver. The monitor reports excessive current or temperature in the electronic control driver. The excessive value concerns the electronic output stage's current or temperature; it must not be read as a coolant-temperature measurement.

Affected system: Hybrid/EV battery thermal management

Symptoms

• System warning may illuminate
• Affected feature may be unavailable
• Symptoms depend on the vehicle

Possible causes

• Hybrid powertrain sensor, actuator, power supply, connector, or control issue
• Module power, ground, or connector fault
• Vehicle-specific mechanical or control issue

What to check

• Record all available module faults
• Record hybrid and electric powertrain module faults with a compatible scan tool. Check the specified low-voltage supplies and module data first; follow vehicle-specific high-voltage safety procedures for further diagnosis.
• Compare results with vehicle-specific service information
• Verify the repair
• Record hybrid and electric powertrain module faults with a compatible scan tool. Check the specified low-voltage supplies and module data first; follow vehicle-specific high-voltage safety procedures for further diagnosis.
• Repair the verified cause and rescan all affected modules

Also written as: P0E1E-00, P0E1E00, POE1E (some scan tools add the fault-type byte, e.g. -00).
