DTC P0801:  Problem in Inhibitor Solenoid Circuit

For KB, KE, KG, and KQ Models


NOTE:

1.Disconnect 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 in the wire between PCM connector terminal C6 and inhibitor solenoid connector.n


NO - Go to 5.

5.Connect 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 substitute a known-good PCM, then recheck. If the symptom/indication goes away with a known-good PCM, replace the original  PCM.n


NO - Go to 8.

8.Disconnect inhibitor solenoid connector.

9.Check for continuity between PCM connector terminal C6 and inhibitor solenoid connector terminal No. 2.

 

Is there continuity?


YES - Repair open in the wire between inhibitor solenoid connector terminal No. 1 and ground (G101), or repair poor ground (G101).n


NO - Repair open in the wire between PCM connector terminal C6 and inhibitor solenoid connector.n
