Motor Electronics Coolant Temperature Sensor Range/Performance
The motor electronics coolant temperature sensor reading is implausible relative to other thermal models or coolant flow estimates.
Affected components
- Motor electronics coolant temperature sensor
- Electric coolant pump
Common causes
- High likelihood: Sensor drift
- Medium likelihood: Low coolant flow
- Low likelihood: Sensor element aged beyond calibration window
Diagnostic notes
- The malfunction indicator lamp may illuminate
