Hi menocal67@yahoo. Com,

DTC P1773: PROBLEM IN A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE B CIRCUIT (2001-03 MODELS)
NOTE:
" Record all freeze data before you troubleshoot.
" This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

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.

Is the resistance 3 10 ©?

YES - Go to step 3.
NO - Replace the A/T clutch pressure control solenoid valve 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.

Is there continuity?

YES - Repair short to ground in the wires between PCM connector terminals B16, 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.

Is the resistance 3-10 ©?

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.

7. Disconnect PCM connector A (31P).

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

Is there continuity?

YES - Check for loose terminal fit, and repair if necessary. 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.

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