DTC P1882:  Problem in Inhibitor Solenoid Circuit

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

1.Disconnect the inhibitor solenoid connector.

2.Measure the resistance between connector terminals at the solenoid connector.

 

Is the resistance 17.1-21.0 W?


YES - Go to 3.


NO - Replace the  inhibitor solenoid.n


3.Disconnect PCM connector C (22P).

4.Check for continuity between PCM connector terminal C6 and body ground.

 

Is there continuity?


YES - Repair short to ground in the wire between PCM connector terminal C6 and the inhibitor solenoid.n


NO - Go to 5.

5.Connect the inhibitor solenoid connector.

6.Disconnect PCM connector A (31P).

7.Measure the resistance between PCM connector terminals C6 and A4 or A5.

 

Is the resistance 17.1-21.0 W?


YES - Update the PCM if it does not have the latest software, or subsutitute a known-good PCM, then recheck. If the symptom/ indication goes away with a known-good PCM, replace the original  PCM.n


NO - Repair loose terminals or open in the wire between PCM connector terminals C6, A4 or A5 and the inhibitor solenoid.n
