Suggested Actions

  1. 1Perform the On-Board (OBD) System Check
  2. 2Using a multimeter, check resistance between ECM pin 14 and ECM pin 15 on the harness to verify if it is between 115 and 135 ohms
  3. 3With Key OFF and Engine Stopped (System Mode = 'Stopped'), disconnect ECM header connection, remove yellow lock from ECM harness side header, and check continuity between diagnostic connector pin 7 and ECM pin 14 and between connector pin 8 and ECM pin 15 on the harness
  4. 4With Key OFF and Engine Stopped (System Mode = 'Stopped'), disconnect EPR/CFV harness connection, remove locks on the harness side of the EPR/CFV connection, check harness continuity of CAN + wire between EPR Pin 2/CFV Pin 2 and ECM pin 14 (CAN1) or Pin 17 (CAN2), and check harness continuity of CAN - wire between EPR Pin 5/CFV Pin 3 and ECM pin 15 (CAN1) or Pin 16 (CAN2)
