A camshaft position sensor is a vital engine management component that tells the electronic control unit (ECU) the position of the pistons as they fire. This information is used by the ECU to calculate fuel injection and ignition timing. If the camshaft position sensor fails, the engine will not run.
To reset a camshaft position sensor, first disconnect the battery. Next, remove the old sensor and install the new one. Finally, reconnect the battery and start the engine.
