What it does
Sensors tell the engine computer what is happening so it can adjust fuel, timing and gauges. Electrical faults often show up as warning lights, rough running or no-start problems, and the right replacement part clears the cause rather than the symptom.
Installation & tips
- Read the code, check the wiring and connector, and clear codes after the new sensor is in.
- Connector and wiring: Corroded connectors mimic a bad sensor.
- Disconnect the battery before you unplug or splice any wiring, and test everything works before you refit trim panels.
