11 INTERMITTENT LOSS OF CMP OR CKP - (P 1391)

The Malfunction Indicator Lamp (MIL) is illuminated and the Diagnostic Trouble Code (DTC) is stored if the Powertrain Control Module (PCM) detects no overlapping pulses between the cam position and crank position sensors for a total of 5 seconds.

This malfunction could possibly be caused by the same components as the previous DTC or by components that may cause a cam position sensor DTC (code 54).
