EV/Hybrid Waste Heat Recovery System Fault
2018-2021 Mitsubishi Outlander PHEV 2.0L I4 PHEV
Description
The waste heat recovery system that captures heat from the motor/inverter to warm the battery or cabin is not functioning.
Symptoms
- Slower battery warm-up in cold weather
- Cabin heating less efficient
- Increased energy consumption for heating
- Range reduction in cold conditions
- Waste heat valve indicator fault
Common Causes
- Heat recovery valve stuck
- Coolant crossover valve failure
- Control module fault
- Coolant circuit air lock
- Temperature sensor error in heat recovery loop
Diagnostic Steps
- Check waste heat recovery valve positions
- Monitor coolant temperatures in recovery circuit
- Command valve positions via scan tool
- Bleed air from heat recovery coolant loop
- Test temperature sensors in recovery circuit
Repair Notes
Replace waste heat recovery valve. Bleed air from coolant circuit. Repair any coolant leaks in the recovery loop.
