The crankshaft position sensor in the 2011 Jeep Patriot with a 3.5L engine is located at the back of the engine block by the transmission. To reach it, you must remove the heat shield by releasing its bolt. If the sensor malfunctions, you may experience issues like sporadic stalling, starting problems, rough acceleration, misfiring, and engine vibrations. A properly functioning crankshaft position sensor is crucial for the vehicle's smooth operation. It tracks the crank's speed and transmits the information to the ECU, which utilizes it to manage the timing of ignition and fuel injection. To replace the sensor, a professional mechanic typically charges between $160 and $200 for parts and labor.
