DTC P0970: Problem in A/T Clutch Pressure
Control Solenoid Valve C Circuit
NOTE:
• Before you troubleshoot, record all freeze data and
any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-4).
• This code is caused by an electrical circuit problem
and cannot be caused by a mechanical problem in the
transmission.
1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine, and wait for at least 1 second.
4. Check for Temporary DTCs or DTCs with the HDS.
Is DT C P097 0 indicated?
−
YES Go to step 8.
NO − Go to step 5.
5. Select Clutch Pressure Control (Linear) Solenoid
Valve C in the Miscellaneous Test Menu, and test
A/T clutch pressure control solenoid valve C with
the HDS.
Does the HDS indicate NORMAL?
−
YES Go to step 6.
NO − Go to step 8.
6. In the Clutch Pressure Control Solenoid Valve
Control menu, select A/T clutch pressure control
solenoid valve C at 1.0 A.
7. Monitor the OBD STATUS for P0970 in the DTCs
MENU with the HDS.
Does the HDS indicate F AILED?
−
YES Go to step 8.
NO − If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals between A/T
clutch pressure control solenoid valve C and the
PCM. If the HDS indicates NOT COMPLETED, go to
step 5.
8. Turn the ignition switch to LOCK (0).

9. Disconnect the A/T clutch pressure control solenoid
valve C connector.
10. Measure the resistance between A/T clutch
pressure control solenoid valve C connector
terminals No. 1 and No. 2.
A/T CLUTCH PRESSURE CONTROL
SOLENOID VALVE C CONNECTOR
Terminal side of male terminals
Is there 3 10 − ?
YES − Go to step 11.
NO − Replace A/T clutch pressure control solenoid
valve C (see page 14-235), then go to step 16.
11. Check for continuity between A/T clutch pressure
control solenoid valve C connector terminal No. 2
and body ground.
A/T CLUTCH PRESSURE CONTROL
SOLENOID VALVE C CONNECTOR
GND (BLK)
Wire side of female terminals
Is there continuity?
YES − Go to step 12.
−
NO Repair open in the wire between A/T clutch
pressure control solenoid valve C and ground
(G101) (see page 22-22), or repair poor ground
(G101), then go to step 16.
