DTC Troubleshooting: P0801 (33-2)

DTC P0801:

Problem in Inhibitor Solenoid Circuit

For KB, KE, KG, and KQ Models

• 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.   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
