  Q: How to replace the Crankshaft Position Sensor on GMC Jimmy?

  A:

  In order to replace the Crankshaft Position (CKP) Sensor, one must first lift up the vehicle. Remove the underbody shield mounting bolts if the underbody shield package is installed, and then the underbody shield. Deplug CKP sensor harness connector, back off the CKP sensor mounting bolt and remove CKP sensor. When fixing a new CKP sensor, make sure it is properly seated to minimize erratic performance and false DTCs by tightening the bolting bolt. Replace the CKP sensor O-ring with a new unit and lubricate it with clean engine oil, and mount surface to be clean and free of burrs then install CKP sensor. Mount the CKP sensor mounting bolt and tighten it to 20 N.m (15 lbs ft). Reconnect the harness connector of the CKP sensor and remount the steering linkage shield tightening the mounting bolts with 33 N.m (24 lb ft). Lastly, lower the vehicle and do the CKP System Variation Learn Procedure.

  Q: How to service and repair the Crankshaft Position Sensor on GMC Jimmy?

  A:

  To service and repair the crank shaft position sensor begins by installing a scan tool and observing the power train control module (PCM) for any dtcs and note that if there are dtcs(non P1336) then refer to the dtc list for more information it is necessary to close the vehicle hood and choose the crankshaft position system variation learn procedure of a scan tool viewing the fuel cut-off for the specified engine. Follow the instruction of the scan tool, which includes, among other things, deploying the parking brake, check blocking the drive wheels, run the ignition from, off to on, press the brake pressing and hold it, start and idle the engine, deactivate the a/c, setting the transmission in park (A/T) or neutral (M/T). The scan tool will consider the monitoring of certain components signals such as ckp sensor activity (DTC P0335 or P0336 if a problem occurs), cmp sensor activity (DTC P0341 if a problem occurs), and engine coolant temperature in order to satisfy that the engine is heated enough before proceeding. Enable the crankshaft position system variation learning procedure on the scan tool, at the time of the learning process, and let the throttle go during the learning process when the engine begins to decelerate, which allows the engine control to be run by the operator. Slowly raise the engine speed to the earlier identified rpm and get off the fuel once fuel cutoff occurs. The scan tool should show a "learn status" learned this ignition"; learned this ignition" if not if no more dtcs, engine symptoms, or refer to dtc list. Lastly, turn-off the ignition 30 seconds once the learn procedure is successfully completed.
