Procedures for Selecting Crank Position Sensing Decode Mode

If both intermittent codes DTC P0336 and DTC P0386 set in addition to DTC P1372, check the time mode in order to determine which sensor is good.

When diagnosing the CKP sensors, enabling a specific decode mode (Angle, Time A, or Time B) may be necessary. In order to enable a specific crank decode, use the scan tool in order to perform the following steps:

1. Turn ON the ignition, with the engine OFF.
2. Select Engine Output Controls.
3. Select Crank Position Sensing Decode Mode.
4. Select the desired mode (Angle, Time A, or Time B) by pressing SELECT STATE.
5. Command the decode mode by pressing COMMAND STATE.

The commanded state remains valid for the current ignition cycle. A specific decode mode can not be commanded with the engine running, or after commanding a desired decode mode. To command a different decode mode, you must cycle the ignition OFF and ON.

If the condition is intermittent, refer to Intermittent Conditions .
