P1599

The PCM has a Diagnostic Trouble Code (DTC) associated with start/stall to assist in diagnosis of intermittent conditions. This DTC will set if the engine is in the RUN mode and Crank Position Sensor (CKP) signal is lost when ignition has not been cycled. This DTC will not turn On the MIL (SERVICE ENGINE SOON) or SERVICE telltale lamps. The code can be set through driver error. An example would be a vehicle equipped with manual transaxle which the clutch is released too quickly stalling the engine.
