Useful checks before replacing parts
- Measure temperature sensor signal voltage, reference, ground, and continuity while checking for short-to-ground conditions.
- Compare sensor data with ambient and other temperature sensors after cold soak and during warm-up.
- Inspect connector terminals, sensor wiring, shared reference circuits, internal harness condition, and fluid contamination at connectors.
