DTC P1882: Problem in Inhibitor Solenoid Circuit
ULEV Model

NOTE: Record all freeze data and review General Troubleshooting Information before you troubleshoot.

1. Turn the ignition switch OFF.
2. Disconnect the solenoid harness connector.





3. Measure the resistance between solenoid harness connector terminal No. 5 and body ground.
Is there 11.7 - 21.0 Ohms?
YES- Go to step 4.
NO- Remove the lower valve body, and check for an open or a short in the solenoid harness. If the wire is OK, replace the inhibitor solenoid.
4. Disconnect TCM connector B (24P).





5. Check for continuity between TCM connector terminal B4 and body ground.
Is there continuity?
YES- Repair short to ground in the wire between TCM connector terminal B4 and the solenoid harness connector.
NO- Go to step 6.
6. Connect the solenoid harness connector.





7. Measure the resistance between TCM connector terminal B4 and body ground.
Is there 11.7 - 21.0 Ohms?
YES- Check the terminal fit at TCM connector terminal B4. If the connection is OK, update the TCM if it does not have the latest software, or substitute a known-good TCM, then recheck. If the symptom/indication goes away with a known-good TCM, replace the original TCM.
NO- Repair open in the wire between TCM connector terminal B4 and the solenoid harness connector.
