DTC P0971 (6-Speed A/T)
DTC P0971 : A/T Clutch Pressure Control Solenoid Valve C
NOTE:
- Before you troubleshoot, review the General Troubleshooting Information - Refer to: How to Troubleshoot the A/T System .
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- If DTC P0971 is stored in the PCM, the transmission does not shift to any gear other than 1st, 2nd, or 5th gear because of the fail-safe function.

| P0971 A/T Clutch Pressure Control Solenoid Valve C |
DTC (A/T)
- Problem verification
- 1. Turn the vehicle to the ON mode.
- 2. Clear the DTC with the HDS.
- 3. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC Freeze Frame P0971 A/T Clutch Pressure Control Solenoid Valve C Is DTC P0971 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between A/T clutch pressure control solenoid valve C and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.
- A/T clutch pressure control solenoid valve C check
- 1. Check the parameter (s) below with the HDS.
Signal Threshold Current conditions Values Unit Values Unit A/T C.P.C. Sol VLV. C Actual More than 0.035 A Do the current condition (s) match the threshold?
YES
A/T clutch pressure control solenoid valve C is OK. Go to step 3.
NO
Faulty A/T clutch pressure control solenoid valve C. Replace the secondary valve body (A/T clutch pressure control solenoid valve C) .
- Open wire check (GND1 line, GND2 LG line)
- 1. Turn the vehicle to the OFF (LOCK) mode.
- 2. Jump the SCS line with the HDS, and wait more than 1 minute.
- 3. Disconnect the following connector.
PCM connector B (51P) - 4. Check for continuity between these test points and body ground individually.
Test condition Vehicle OFF (LOCK) mode PCM connector B (51P): disconnected Connector Test circuit Terminal PCM connector B (51P) - Refer to:
PCM Connector for Inputs and Outputs (16-20 6-Speed A/T)GND1 No. 11 GND2 LG No. 20 Is there continuity?
YES
The GND1 and GND2 LG wires are OK. Replace the PCM - Refer to: PCM Removal and Installation (6-Speed A/T, 16-18 9-Speed A/T) .
NO
Repair an open in the GND1 wire and/or the GND2 LG wire between the PCM and ground (G101) or repair poor ground (G101).
