DTC P1773: Problem in A/T Clutch Pressure Control 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. Disconnect A/T clutch pressure control solenoid valve B connector (2P).
2. Measure A/T clutch pressure control solenoid valve B resistance at the solenoid valve connector.

A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE B CONNECTOR

Terminal side of male terminals

Is the resistance about 5 ohm?

YES - Go to step 3.

NO - Replace the A/T clutch pressure control solenoid valves A and B.

3. Disconnect PCM connectors B (24P) and C (22P).

4. Check for continuity between PCM connector terminal B16 and body ground and between terminal C8 and body ground.

PCM CONNECTORS

Wire side of female terminals

Is there continuity?

YES - Repair short to ground in the wires between PCM connector terminals B16 and C8 and the A/T clutch pressure control solenoid valve B.

NO - Go to step 5.

5. Connect A/T clutch pressure control solenoid valve B connector.
6. Measure the resistance between PCM connector terminals B16 and C8.

PCM CONNECTORS

Wire side of female terminals

Is the resistance about 5 ohm?

YES - Go to step 7.

NO - Repair loose terminal or open in the wires between PCM connector terminals B16 and C8 and the A/T clutch pressure control solenoid valve B.
