  Q: How to service and repair the Crankshaft Position Sensor on Cadillac Seville?

  A:

  It gets more complicated by installing a scan tool and to check on the powertrain control module for dtcs as you debug it. If there are any other dtcs which are not p1336, refer to a diagnostic trouble code (DTC) list addressing a particular dtc. Next, choose the crankshaft position variation learn procedure on a scan tool and monitor the fuel cut-off in the engine. Follow the scan tool's instructions: block the drive wheels, engage the parking brake of the vehicle, turn the ignition of the vehicle from off to on, press and hold the brake pedal, start and let the engine idle, turn off the a/c, and put the tranmission for the vehicle in park (A/T) or neutral (M/T). The scan tool will scan certain component signals, for instance; ckp sensor activity, cmp sensor activity and fuel efficiency temperature. If there is something that is not met, deal with each of them accordingly. After being ready, activate the crankshaft position system variation learn procedure, and during that procedure, the throttle should be released instantly when the engine starts to decelerate, allowing the engine control to switch back to the operator. Gradually increase rpm of the engine to that observed rpm, and release the throttle when fuel cut-off is achieved. The scan tool will show "learn status: learned this ignition"; it may also appear as "learned this ignition"; if no dtc displays display this message and no more dtcs, check for symptoms of the engine and if a dtc is present reference the list code for the respective codes. Finally, then, turn off the ignition after successfully completing the learn procedure for 30 seconds.

  Q: How to replace the Crankshaft Position Sensor on Cadillac Seville?

  A:

  Begin by supporting the vehicle with an appropriate lifting method. Next disconnect the sensor's electrical connector followed by removing the bolt that retains the crankshaft sensor and finally remove the crankshaft sensor. Check the O-ring on the crankshaft sensor for signs of deterioration before you decide if replacement is needed and apply fresh engine oil to the O-ring. Fully install the CKP sensor into the engine block to avoid CKP sensor DTC settings before you install the crankshaft sensor with its retaining bolt and apply torque at 8-11 N.m (70-100 lb in). Connect the crankshaft sensor electrical connector while lowering the vehicle to perform engine operation that enables leak detection around the sensor. Finish the procedure by running the CKP System Variation Learn Procedure.
