The Walker Products Engine Crankshaft Position Sensor (part number 235-91046) is a direct-fit replacement for 1993-2005 Buick, Chevrolet, Oldsmobile, and Pontiac vehicles with 3.1L and 3.4L engines. A crankshaft position sensor monitors the crankshaft's rotational speed and position, providing vital data for precise ignition timing and fuel injection in engines.
Features:
- With accurate crankshaft position data, the engine control module can fine-tune fuel injection timing, leading to improved fuel combustion efficiency, reduced fuel consumption, and lower emissions.
- Crankshaft position sensors can identify irregularities in engine cycles, aiding in the detection of misfires. This enhances overall engine efficiency and reduces exhaust emissions.
- Crankshaft position sensors track the rotational speed and position of the crankshaft, providing essential data to the engine control module for accurate timing of fuel injection and ignition.
- By working alongside camshaft sensors, crankshaft position sensors enable precise coordination between valve and piston movements, optimizing engine performance and minimizing the risk of damage.
- Designed to withstand extreme engine conditions, crankshaft sensors endure temperature fluctuations, mechanical vibrations, and exposure to engine fluids, ensuring consistent and reliable operation.
