Keep your engine's timing reference reading true with the Standard Ignition Engine Crankshaft Position Sensor PC983. It drops in as a direct-fit replacement for the listed applications, including the 2017-2021 BMW 230i, 2016-2018 BMW 330e, 2016-2018 BMW 340i, 2017-2021 BMW 540i, 2014-2017 BMW X5, 2014-2021 MINI Cooper and many more — see the Buyer's Guide tab for the full list, covering L3-1.5L, L4-2.0L and L6-3.0L engines.
A crankshaft position sensor tracks the rotation and position of the crankshaft and sends that signal to the engine control module, which uses it to set ignition timing and fuel injection.
- Core function: Reports crankshaft speed and position to the ECM so it can time spark and fuel delivery.
- Signs it may need replacing: hard starting, a no-start, stalling, an intermittent misfire or an erratic tachometer can be signs this sensor may need attention.
- Application fit: Installs on the listed BMW and MINI applications, with one sensor used per vehicle.
- Diagnose first: These symptoms can have other causes — confirm the sensor is the cause before replacing it.
Manufacturer part number PC983.
