152 RENR5042-02 Troubleshooting Section Expected Result: i02290022 Injector Solenoid Circuit - Test The resistance is less than 5 Ohms. Results: SMCS Code: 1290-038 OK – The resistance is less than 5 Ohms. Proceed to Test Step 11. System Operation Description: Use this procedure to troubleshoot any suspect problems with the injector solenoids. Not OK – The resistance is greater than 5 Ohms. Repair: Repair the wire between terminal 86 of the ether relay and terminal P1-10. Verify that the original problem is resolved. Use this procedure for the following diagnostic codes: 1-05 Injector Cylinder 1 open circuit STOP. 1-06 Injector Cylinder 1 short Test Step 11.
Check for a Short in the Wire between the ECM and the Ether Relay 1-11 Injector Cylinder #1 fault 2-05 Injector Cylinder 2 open circuit A. Turn the keyswitch to the OFF position. 2-06 Injector Cylinder 2 short B. Disconnect the wire on terminal 86 of the ether relay. 2-11 Injector Cylinder #2 fault C. Disconnect the J1/P1 and J2/P2 connectors. 3-05 Injector Cylinder 3 open circuit D. Measure the resistance between terminal P1-10 and all of the other terminal in the P1 and P2 connectors. Measure the resistance between wire P1-10 and engine ground. 3-06 Injector Cylinder 3 short 3-11 Injector Cylinder #3 fault 4-05 Injector Cylinder 4 open circuit E.
Return the wiring to the original configuration. 4-06 Injector Cylinder 4 short Expected Result: 4-11 Injector Cylinder #4 fault Each check of the resistance indicates an open circuit. 5-05 Injector Cylinder 5 open circuit Results: 5-06 Injector Cylinder 5 short 5-11 Injector Cylinder #5 fault OK – Each check of resistance indicates an open circuit. 6-05 Injector Cylinder 6 open circuit Repair: The problem may be intermittent. If the problem is intermittent, refer to Troubleshooting, “Electrical Connectors - Inspect”. 6-06 Injector Cylinder 6 short STOP. 6-11 Injector Cylinder #6 fault Not OK – At least one check of the resistance does not indicate an open circuit.
There is a problem with the wiring. There may be a problem with a connector. You have been directed to this procedure from Troubleshooting, “Troubleshooting without a Diagnostic Code”. Perform this procedure under conditions that are identical to the conditions that exist when the problem occurs. Typically, problems with an injector solenoid occur when the engine is warm and/or when the engine is under vibration (heavy loads). Repair: Repair the wiring and/or the connector. Replace parts, if necessary. Verify that the original problem is resolved. STOP.
