Good To Know

Q: Will this sensor need programming after installation? A: No programming is required; the ECU reads the signal directly from the sensor once it is connected and the engine is started.

Q: Should I replace the connector or wiring at the same time? A: Inspect the existing harness plug for corrosion or cracked insulation, since a damaged connector can mimic sensor failure even with a new part installed.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
