Useful checks before replacing parts
- Check sensor voltage, reference supply, ground, connector condition, freeze-frame temperature, inverter temperature, and related low-voltage sensor codes.
- Inspect for short-to-ground faults, low reference voltage, corroded terminals, coolant intrusion, damaged harness insulation, and incorrect sensor resistance.
- Measure the signal at both the sensor and controller to separate a sensor fault from wiring or module input trouble.
