DTC P0963

DTC P0963 : A/T Clutch Pressure Control Solenoid Valve A

NOTE:

Before you troubleshoot, review the General Troubleshooting Information - Refer to: How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the A/T System (2014 2015), .
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
If DTC P0963 is stored in the PCM, the transmission does not shift to 2nd or 5th gear because of the fail-safe function.

P0963 A/T Clutch Pressure Control Solenoid Valve A

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.

Is DTC P0963 indicated?

YES

The failure is duplicated. Go to step 2.

Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between A/T clutch pressure control solenoid valve A 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 A check

-1. Check the parameter(s) below with the HDS.

Signal	Threshold		Current conditions
Signal	Values	Unit	Values	Unit
A/T C.P.C. Sol VLV. A Actual	More than 0.035	A

Do the current condition(s) match the threshold?

YES

A/T clutch pressure control solenoid valve A is OK. Go to step 3.

Faulty A/T clutch pressure control solenoid valve A. Replace the secondary valve body (A/T clutch pressure control solenoid valve A) .

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.

- 3. Disconnect the following connector.

PCM connector B (51P) - Refer to: How to Troubleshoot the A/T System (2014 2015), or How to Troubleshoot the Fuel and Emissions Systems, or How to Troubleshoot the Brake Booster Pressure Monitoring System (2016 2017 2018 2019 2020), or How to Troubleshoot the Fuel and Emissions Systems(With Auto Idle Stop System) (2016)

- 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)	GND1	No. 11 (BLK)
PCM connector B (51P)	GND2 LG	No. 20 (BRN)

Is there continuity?

YES

The GND1 and GND2 LG wires are OK. Replace the PCM - Refer to: PCM Removal and Installation (2014 2015) .

Repair an open in the GND1 wire and/or the GND2 LG wire between the PCM and ground (G101) or repair poor ground (G101).
