DTC P0970:  Problem in A/T Clutch Pressure Control Solenoid Valve C Circuit

NOTE:

1.Clear the DTC with the HDS.

2.Check that DTC P0970 recurs.

Is DTC P0970 indicated?


YES - Go to 6.


NO - Go to 3.


3.Choose Clutch Pressure Control Solenoid Control in Miscellaneous Test Menu, and test the A/T clutch pressure control solenoid valve C with the HDS.

4.Drive with the A/T clutch pressure control solenoid valve C at 1.0A in Clutch Pressure Control Solenoid Control menu.

5.Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0970.

Did the result indicate a fail?


YES - Go to 6.


NO - Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the A/T clutch pressure control solenoid valve C and PCM. If the tester indicates NOT COMPLETE, return to 3 and recheck.n


6.Turn the ignition switch OFF.

7.Disconnect the A/T clutch pressure control solenoid valve C connector.

8.Measure A/T clutch pressure control solenoid valve C resistance at the solenoid connector.

 

Is there 3-10 W?


YES - Go to 9.


NO - Replace the A/T clutch pressure control solenoid valve C, then go to 12.


9.Check for continuity between A/T clutch pressure control solenoid valve C connector terminal No. 2 and body ground.

 

Is there continuity?


YES - Go to 10.


NO - Repair open in the wire between the A/T clutch pressure control solenoid valve C and ground (G101), or repair poor ground (G101), then go to 12.

10.Turn the ignition switch ON (II).

11.Measure the voltage between A/T clutch pressure control solenoid valve C connector terminals No. 1 and No. 2.

 

Is there about 11 V as the ignition switch is turned to the ON (II) position?


YES - 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.n


NO - Repair open or short in the wire between PCM connector terminal C7 and A/T clutch pressure control solenoid valve C, then go to 12.


12.Clear the DTC with the HDS.

13.Test-drive the vehicle for several minutes in the D position in all five gears.

14.Check the OBD status in DTC Monitor Tool from DTCs/Freeze Data in A/T Mode Menu for a pass/fail test of code P0970.

Did the result indicate a pass?


YES - The problem has been corrected.n


NO - Return to 1 and recheck.n
