DTC P0970: Problem in A/T Clutch Pressure
Control Solenoid Valve C Circuit
NOTE:
• Record all freeze data and review General
Troubleshooting Information (see page 14-4) before
y o u troubleshoot.
• This code is caused by an electrical circuit p r o b l e m
and cannot be caused by a mechanical p r o b l e m in the
transmission.
1. Clear the DTC w i t h the HDS.
2. Check that DTC P0970 recurs.
Is DTC P0970 indicated?
Y E S — G o t o step 6.
N O — G o t o step 3.
3. Choose Clutch Pressure Control Solenoid Control
in Miscellaneous Test M e n u , and test the A/T clutch
pressure control solenoid valve C w i t h the HDS.
Is the system normal?
YES—Go to step 4.
NO—Go to step 6.
4. Drive w i t h the A/T clutch pressure control solenoid
valve C at 1.0 A in Clutch Pressure Control Solenoid
Control m e n u .
5. M o n i t o r the OBD status for P0970 in the DTCs/
Freeze Data in A/T Mode Menu for a pass/fail.
Does the result indicate a fail?
Y E S — G o t o step 6.
NO—Intermittent failure, the system is OK at this
t i m e . Check for poor connections or loose terminals
at the A/T clutch pressure control solenoid valve C
and the PCM. If the tester indicates NOT
COMPLETE, return to step 3 and r e c h e c k . •
6. Turn the ignition switch OFF.
7. Disconnect the A/T clutch pressure control solenoid
valve C connector.
8. Measure the A/T clutch pressure control solenoid
valve C resistance at the solenoid connector.
