DTC P0758: Problem in Shift Solenoid Valve B Circuit NOTE:

- Record all freeze data before you troubleshoot.
- The illustration shows the example of connector terminal arrangement; connector terminal arrangement varies with the models.

1. Turn the ignition switch OFF.
2. Disconnect PCM connectors A (31P) and C (22P).
3. Turn the ignition switch ON (II).
4. Measure the voltage between PCM connector terminals C4 and A23 or A24.

PCM CONNECTORS

Wire side of female terminals

Is there voltage?

YES - Repair short to power in the wire between PCM connector terminal C4 and the shift solenoid valve B.

NO - Go to step 5.

5. Turn the ignition switch OFF.

6. Measure the resistance between PCM connector terminals C4 and A23 or A24.

PCM CONNECTORS

Wire side of female terminals

Is there 12-25 ohm?

YES - Check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.

NO - Go to step 7.

7. Check for continuity between PCM connector terminal A23 and body ground and between terminal A24 and body ground.

PCM CONNECTOR A (13P)

Wire side of female terminals

Is there continuity?

YES - Go to step 8.

NO - Repair open in the wires between PCM connector terminals A23 and A24 and ground (G101), or repair poor ground (G101).
