Setting a code P0322 for missing or erratic 4x reference signal. Also experiencing long crank times. Tests/Procedures: 1. Check for an erratic signal from one or both of the CKP sensors. 2. Check for a square wave signal at ignition module on the Purple/White wire. 3. Verify the wiring from the ignition module to the Powertrain Control Module (PCM).
P0322 ICM 4X Reference Circuit Malfunction - With Automatic TransmissionPossible Causes Setting Conditions •Fuel control signal circuit is open •Fuel control signal circuit is shorted to ground •IC module has failed •PCM has failed DTC P0340 and P1376 not set; engine running; CMP sensor signal detected in the last 4 seconds, and the PCM did not detect any 4X fuel control pulses for 4 seconds. This code sets in 1 Trip(s).
