• Q: How to service and repair the Crankshaft Position Sensor on 2002 Chevrolet Cavalier?

  A: To service and repair the Crankshaft Position Sensor firstly install a scan tool and monitor power train control module for dtcs. If the following other dtcs exist, check against the applicable dtc that caused it. Choose the crankshaft position (CKP) variation learn function on the scan tool and monitor the fuel cut-off of the engine. Follow the scan tool's instructions: block the drive wheels, set the parking brake of the vehicle, cycle the ignition from off to on, apply and hold the brake pedal, start and idle the engine, deactivate the a/c, and switch the transmission of the vehicle to the park (A/T) for the automatic transmission format or switch the transmission to neutral (M/T) for manual transmission format. The scan tool will check for activities of ckp sensor, cmp sensor, and engine coolant temperature (ECT); if the ect is too cool, idle the engine until it warms up to the right temperature. Turn on the ckp system variation learn procedure on the scan tool and during doing so release the throttle as soon as possible once the engine has started to decelerate, thereby allowing the control of the engine to return to the operator. Gradually increase the engine speed to that observed rpm and throttle release when fuel cut-off is achieved. The status of the scan tool will show "learn status: learned this ignition." if the message does not appear and no more dtcs are set, check for engine mechanical symptoms. If there is a dtc, refer to dtc list for the relevant dtc. Lastly, shut off the ignition immediately after achieving the learn procedure for 30 seconds.
