Disconnect the Ignition Control (IC) module connector C1, and then using a Digital Volt Ohmmeter (DVOM), measure the resistance between terminals A and B (harness side). The resistance should be 800- 1600 ohms. Measure the resistance between pins E and F of the same connector. The resistance should be 800 - 1600 ohms. If the resistance is out of normal values in step 1, disconnect the crankshaft sensor A and measure the resistance across terminals A and B at the sensor connector. The meter should read LO. If the resistance was OK in test 1, but not within normal specifications on step 2, disconnect crankshaft sensor B and measure the resistance across terminals A and B at the sensor connector, the meter should read LO. If the reading with wires from the IC to the crankshaft sensor is LO, jump the crankshaft sensor wires together at the crankshaft sensor end and then measure the resistance of the wires from the IC pins A-B for crankshaft sensor A and from E-F for crankshaft sensor B. The resistance should be less than 5 ohms. If the wires check OK, the crankshaft sensor will need to be replaced.

 

P0322 ICM 4X Reference Circuit Malfunction - With Automatic Transmission

Possible CausesSetting 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).

P1350 Ignition Control (IC) Circuit Malfunction - With Automatic Transmission

Possible CausesSetting Conditions
  • Bypass circuit is open, shorted to ground or shorted to voltage
  • IC signal circuit is open, shorted to ground or shorted to voltage
  • IC module has failed
DTC P0322 and P1376 not set; engine cranking with at least one 4X REF pulse detected, and the PCM detected Ignition Control (IC) pulses with the engine cranking, or it detected at least one 4X REF pulse while it did not detect any IC pulses with the engine running.

This code sets in 1 Trip(s).
This code will turn on the MIL (Malfunction Indicator Lamp)

P1375 IC Module 24X Reference Circuit High Input - With Automatic Transmission
Possible CausesSetting Conditions
  • CKP Sensor 'A' signal circuit is open or shorted to ground
  • Crank Sensor 'A' has failed
  • Crank Sensor 'B' low circuit is shorted to CKP 'A' high circuit
  • Crank Sensor 'B' has failed
  • IC module has failed
  • PCM had failed
DTC P1376 not set; engine speed over 496 rpm, at least 7 CMP pulses detected since key "on", and the PCM detected the 24X signal was high, and that it did not receive any 24X REF pulses during the last eight (8) 4X REF pulses.

This code sets in 1 Trip(s).
This code will turn on the MIL (Malfunction Indicator Lamp)
