Crankshaft Position Sensor

The Bosch Engine Crankshaft Position Sensor plays a crucial role in your vehicle's performance by monitoring the position and rotational speed of the crankshaft. This information is essential for the Engine Control Unit (ECU) to accurately time fuel injection and ignition, preventing poor performance, stalling, or the engine not starting at all. It utilizes either a magnetic or Hall-effect design to detect the crankshaft's rotation via a reluctor or tone wheel. Common failure modes include internal short-circuiting due to heat and vibration, as well as contamination from oil or debris. Symptoms of a failing crankshaft position sensor can range from a no-start condition, stalling when warm, erratic tachometer readings, to misfires across multiple cylinders. While a P0335 code may appear, it's not always indicative of a failed sensor. This Bosch sensor is a direct replacement for OE numbers 022957147 and MFG numbers 0261210145, ensuring a precise fit for compatible vehicles. Bosch, a world-leading supplier of engine electronics and sensors, brings over 130 years of automotive innovation to this product.
