Note: The engine may still start even if either the CKP or CMP (crank position or cam position) fails. The PCM
eventually sorts out engine position and can start the vehicle on just one of these two inputs. However, there is a
delay in starting until the PCM can establish sync. A DTC is set and the MIL illuminates if either of the CKP or
CMP Sensor signals are not present during engine cranking.
