• Q: How is the Crankshaft Position Sensor Variation Learn Procedure Performed on 2001 Chevrolet Corvette?

  A: The variation compensating values for the Crankshaft position (CKP) system are stored into the non-volatile memory in the pcm following through a learn procedure; which is required if a dtc p1336 sets; or the pcm, engine, crankshaft, crank shaft Harmonic Balancer or Crankshaft position sensor has been replaced. Make the vehicle parking brake and block the wheels on drive before starting the procedure to ensure safety. Second fuel cut off; let go of the throttle when the engine comes up to the under this fuel cut off, for controlled deceleration. Engine coolant temperature less than 70 degrees (158 degrees) and any powertrain dtc's other than dtc p1336 prohibits the learn procedure can be initiated. In addition, violation of camshaft position signal circuit, 3x reference circuit, or 18x reference will inhibit involved to learn function. Start by engaging the parking brake, imprisoning the driver wheels, and making sure that the hood is shut. Start the engine and wait until the coolant temperature rises to at least 70°c (158°F), and then shut off the ignition. Use the scan tool to select and enable the Crankshaft position variation learn procedure, start the vehicle, apply the service Brake Pedal firmly to release the transaxle parking function to the park position, works, and increase the accelerator pedal position until the ckp system variation learn fuel cutoff is reached at 5,150, releasing the throttle when the second fuel cutoff takes place. Compensating values are learned when rpm reduces back to idle. Check the dtc status for dtc p1336 after completion; if it shows that dtc p1336 had run and passed, the procedure is over. If it did not work or run, search for other dtcs and if only p1336 is set, perform learn again if required.
