The location of the crankshaft position sensor varies depending on the make and model of the 2012 Chevy Malibu 2.4, but it is always located near the crankshaft itself. To replace the sensor, you can expect to pay between $190 and $300 for the part, and around an additional $200 for installation labor. The sensor plays a crucial role in ensuring the crankshaft maintains the correct speed. If the sensor malfunctions, you may experience issues such as stalling, shaking, rough acceleration, and the check engine light illuminating. This can result in incorrect engine timing and poor firing, causing immediate problems and potentially damaging the engine over time, leading to further costs.
The 2012 Chevy Malibu 2.4's crankshaft position sensor is located below the engine, close to the timing cover.
