Engine Crankshaft Position Sensor Spacer

Description

Walker Products Engine Crankshaft Position Sensor Spacers are OE Replacement components designed to maintain the critical air gap between the crankshaft position sensor and the tone ring or reluctor wheel. This precise spacing is essential for generating a clean, consistent signal that the engine control unit (ECU) uses for ignition timing, fuel delivery, and engine synchronization. If the gap is too wide or too narrow, it can lead to inaccurate sensor readings, hard starting, misfires, or fault codes related to crankshaft signal loss. Walker crank sensor spacers are manufactured to match OE specifications for thickness, diameter, and material composition—ensuring correct magnetic field alignment and long-term reliability. Built from heat- and vibration-resistant materials, these spacers are designed for the extreme conditions found around the crankshaft and sensor mounting points. Designed for exact OE fit, they install directly between the sensor and engine block or mounting bracket with no modification required. Whether replacing a lost spacer during sensor service, correcting sensor alignment, or resolving timing-related drivability issues, Walker Crankshaft Position Sensor Spacers help restore precise engine timing and reliable sensor output across gasoline and diesel applications.
