Keep ignition timing and fuel injection in sync with the Walker Products Engine Crankshaft Position Sensor 235-1620. It fits many vehicles as a direct-fit replacement for the listed applications, among them the 2011-2015 Chevrolet Cruze, 2013-2021 Chevrolet Trax and 2012-2020 Chevrolet Sonic.
A crankshaft position sensor tracks the crankshaft's rotational speed and position, feeding that data to the engine control module for accurate ignition and fuel-injection timing.
- Core function: Monitors crankshaft speed and position and reports it to the ECM for precise timing.
- Works with the cam sensor: Coordinates with the camshaft position sensor so valve and piston movements stay in step.
- Built for the engine bay: Designed to hold up to temperature swings, mechanical vibration and exposure to engine fluids.
- Cycle monitoring: Accurate position data helps the ECM fine-tune injection timing and can aid misfire detection.
Signs the original may need replacing include a no-start, intermittent stalling, hard starting or misfires — diagnose the cause first, and if a failed crankshaft position sensor is behind it, this replaces it.
