DTC P0801:

Problem in Inhibitor Solenoid Circuit

NOTE:

Record all freeze data and review General Troubleshooting Information before you troubleshoot.
The illustration shows the example of connector terminal arrangement; connector terminal arrangement varies with the models.

1.	Disconnect inhibitor solenoid connector.

2.	Measure the resistance between connector terminals at the solenoid connector. INHIBITOR SOLENOID CONNECTORTerminal side of male terminals 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. PCM CONNECTOR C (22P)Wire side of female terminalsSOL INH (GRN/BLK) 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).

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.

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
