2002 Chevrolet Camaro Parts Questions & Experts Answers

• Q: What are the steps involved in performing the Crankshaft Position Sensor system variation learn procedure on 2002 Chevrolet Camaro?

  A: The Crankshaft position (CKP) system variation compensation values require storage in pcm non-volatile memory following a learn procedure that should be done either after setting dtc p1336 or after any replacement of the pcm, engine, crankshaft, crankshaft Harmonic Balancer, or Crankshaft position sensor. The starting procedure must be done after blocking drive wheels and setting the vehicle parking brake to guarantee safety. When the engine reaches the second fuel cut-off, reduce throttle pressure for a controllable engine slow-down. The learn procedure cannot start when the engine coolant temperature dips below 70°c (158°F) or when any powertrain fault codes exist that are not dtc p1336. The learn function becomes disabled when the engine control module detects problems in the camshaft position signal circuit along with the 3x or the 18x reference circuits. First, apply the parking brake before blocking the driver wheels and ensure the hood remains shut. Turn on the engine after reaching at least 70°c (158°F) engine coolant temperature and finish by shutting off the ignition. Through the scan tool you must select and activate ckp system variation learn while starting the vehicle and pressing the service Brake Pedal firmly with the transaxle in park position. Introduce the accelerator pedal to hit the 5,150 rpm ckp system variation learn fuel cut-off before you ease off the pedal at the second fuel cut-off point. The learned compensating values occur after rpm drops back to idle. Check dtc status for dtc p1336 after completing the process this procedure is finished when the dtc p1336 shows its test has both occurred and completed successfully. Check all other dtcs after a failed or incomplete run of this procedure while p1336 remains the only found code to execute the learn function again.
