DTC P0315 for the 2.8L, 3.0L, 3.2L, or 3.6L engine
Circuit / System Description
The crankshaft position system variation learn feature is used to calculate reference period errors caused by slight tolerance variations in the crankshaft, and the crankshaft position sensor. The calculated error allows the engine control module (ECM) to accurately compensate for reference period variations. This enhances the ability of the ECM to detect misfire events over a wider range of engine speed and load.
The crankshaft position system variation compensating values are stored in ECM memory after a learn procedure has been performed and the ignition switch is turned to the OFF position for at least 30?s. If the actual variation is not within the crankshaft position system variation compensating values stored in the ECM, DTC?P0300 may set.
If the crankshaft position system variation values are not stored in the ECM memory or a proper ECM power down does not occur after completing the Crankshaft Position Learn Procedure, DTC?P0315 sets.
