Setup, Compatibility & Care
To install this sensor, first ensure the vehicle's engine is completely cool and the battery is disconnected for safety. Locate the sensor housing on your engine block—refer to your vehicle’s service manual for the exact position, as it varies by engine configuration. Carefully remove the existing unit, clean the mounting surface of any debris or oil residue, and insert the Walker 235-1400. Ensure the mounting bolt is torqued to manufacturer specifications to maintain the correct gap between the sensor and the reluctor wheel. This sensor is fully compatible with Audi, Seat, Skoda, and VW vehicles requiring OEM part 06H 906 433. To ensure longevity, keep the wiring harness plug free of corrosion and ensure the heat shield is correctly positioned to protect the sensor from excessive exhaust heat.
