Your vehicle’s crankshaft position sensor is located near the bottom of the engine by the crankshaft. That makes sense because it’s the crankshaft position sensor’s job to measure the crankshaft location. When you’re trying to track down the crankshaft position sensor, look towards the engine’s bottom, generally on one of the sides.
If your defective crankshaft position sensor is extremely out of sync, you might have trouble getting your vehicle started. Furthermore, you might have difficulty keeping it started. This is usually only a problem when the problem has persisted for some time, and you likely have various other underlying issues too.
There are many diagnostic codes for various problems and they can be checked using a diagnostic scan tool. If the code lies between P0335 and P0338 it indicates that the problem is with the crankshaft sensor. This is one of the simplest ways to diagnose a problem with the crankshaft position sensor.
It is responsible for telling the ECM the exact location of the crankshaft as well as the RPM (rotations per minute) of the engine. With this information the ECM knows the position of each piston in each cylinder. Using the cam sensor readings, as well as the crank sensor readings, the ECM knows exactly which injector needs to be activated.
The sensor itself will cost between $8.00 and $49.00 (US) on Amazon. Labor will run between $60.00 and $180.00 depending on the location of the sensor. Start by locating the sensor which can be done by inspecting the engine at looking for any sensor at the lower level that matches the new sensor you have just purchased.
