Problem in A/T Clutch Pressure
Control Solenoid Valve B Circuit
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-247)
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 the 2P connector from A/T clutch
pressure control solenoid valve B.
2. Measure A/T clutch pressure control solenoid
resistance at the solenoid valve connector.
Go to step 3.
Replace the A/T clutch pressure control
solenoid valve B (see page 14-361).
3. Disconnect PCM connector B (25P).
4. Check for continuity between PCM connector
terminals B18 and body ground, and between B25
and body ground.
Repair short to ground in the wires between
PCM connector terminals B18 and B25, and A/T
clutch pressure control solenoid valve B.
Go to step 5.
5. Connect the A/T clutch pressure solenoid valve B
connector.
6. Measure the resistance between PCM connector
terminals B18 and B25.
Go to step 7.
Repair loose terminal or open in the wires
between PCM connector terminals B18 and B25,
and A/T clutch pressure control solenoid valve B.
