Conditions for Running the DTC
| • | No CMP or CKP sensor DTC(s) set. |
| • | Engine Coolant Temperature is greater than 70° C (158° F). |
Conditions for Setting the DTC
| • | Crankshaft position system variation values are not stored in the PCM memory. |
Action Taken When the DTC Sets
| • | The PCM will illuminate the MIL during the first trip in which the diagnostic test has been run and failed. |
| • | The PCM will store conditions which were present when the DTC set as Freeze Frame and Fail Records data. |
Conditions for Clearing the MIL/DTC
| • | The PCM will turn the MIL OFF during the third consecutive trip in which the diagnostic has been run and passed. |
| • | The history DTC will clear after 40 consecutive warm-up cycles have occurred without a malfunction. |
| • | The DTC can be cleared by using the scan tool Clear Info function or by disconnecting the PCM battery feed. |
Diagnostic Aids
The crankshaft position system variation compensating values are stored in the PCM non-volatile memory after a learn procedure has been performed. If the actual crankshaft position variation is no within the crankshaft position system variation compensating values stored in the PCM, DTC P0300 may set (refer to Diagnostic Aids for DTC P0300).
The crankshaft position system variation learn procedure must be performed when replacing the PCM to clear DTC P1336. The crankshaft position system variation learn procedure is also required when the following service procedures have been performed, regardless of whether or not DTC P1336 is set:
| • | Engine replacement. |
| • | Crankshaft replacement. |
| • | Crankshaft balancer replacement. |
| • | Crankshaft position sensor replacement. |
| • | Any engine repair(s) which disturbs crankshaft/harmonic balancer to crankshaft position sensor relationship. |
