    Q:
    How to service and repair the Crankshaft Position Sensor on Chevrolet Avalanche 2500? Posted by Customer
    A:
    Start Crankshaft Position Sensor service by using a scan tool to check powertrain control module dtcs while recognizing that you must check other present dtcs against the diagnostic trouble code (DTC) list. Through the scan tool user interface select the crankshaft position variation learn procedure then monitor the engine fuel cut-off duration. Complete the scan tool sequence by blocking drive wheels while activating the parking brake followed by ignition cycling (OFF to ON) and sustained brake pedal pressure before starting the engine to idle it while turning off the a/c unit then placing the vehicle in park (A/T) or neutral (M/T). During the check the scan tool assesses three essential sensor signals: crankshaft position (CKP), camshaft position (CMP), and engine coolant temperature (ECT). When encountering issues check the relevant dtc for assistance. After the conditions are satisfied enable crankshaft position system variation learn then carefully release the throttle during engine deceleration to allow engine control to restore itself to the operator. The engine speed must be smoothly raised to match the specified rpm before releasing the throttle at the moment fuel cutoff occurs. During the procedure the scan tool shows the message "learn status:" learned this ignition"; engine management will show "learn status: learned this ignition" unless other dtcs are triggered or if this message fails to display. At that point, examine engine performance signs. Refer to the dtc list to analyze any present dtc before proceeding. After completing a learn procedure turn off the ignition for thirty seconds to finalize the process.
