DTC P1768: Problem in A/T Clutch Pressure
Control Solenoid Valve A Circuit
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-3) 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 A connector (2P).
2. Measure A/T clutch pressure control solenoid valve
A resistance at the solenoid valve A connector.

SOLENOID VALVE A CONNECTOR
Terminal side of male terminals
Is the resistance 3 10
YES Go to step 3.
NO Replace the A/T clutch pressure control
solenoid valve A and B (see page 14-133).
3. Disconnect PCM connectors B (24P) and C (22P).
