Chevy express 1999 didn't start, i have a code p1336. i've change the crank shaft sensor but it didn't strat and i have a P1336 code again
Trouble Code: P1336
\015\012CKP Sensor System Variation Not Learned
\015\012\015\012Set the parking brake and block the drive wheels for safety. \015\012 \015\012Verify the hood is closed. \015\012 \015\012Read the trouble codes. If a code is set, refer to that code. \015\012 \015\012Start the engine. Allow engine temperature to reach at least 158?F (70?C). Then key off. \015\012 \015\012Select Crankshaft Position Variation Learn procedure on Scan Tool & start the vehicle. \015\012 \015\012Apply the brake pedal firmly and verify the selector is in Park. \015\012 \015\012Increase accelerator pedal position until fuel cutoff is reached at the test rpm (e.g., 5150). Quickly release the accelerator pedal after fuel cutoff is reached. The CKP system variation compensating values are learned when the engine speed (rpm) decreases back to idle speed and the procedure terminates. \015\012 \015\012Read the trouble codes and recheck for DTC P1336. \015\012 \015\012If DTC P1336 runs and passes, the CKP system variation "learn" procedure is complete. If not, look for other codes. If no codes are set, repeat the test procedure.
