DTC P0962

DTC P0962 : A/T Clutch Pressure Control Solenoid Valve A (Open or Short)

NOTE:

Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information .
This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
If DTC P0962 is stored in the PCM, the transmission does not shift to 2nd or 5th gear because of the fail-safe function.

P0962 A/T Clutch Pressure Control Solenoid Valve A (Open or Short)

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 P0962 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.

Fuse check

-1. Turn the vehicle to the OFF (LOCK) mode.

-2. Check the following fuse.

Fuse	No. C2 (10 A)
Location	Under-hood fuse/relay box

Is the fuse OK?

YES

The fuse is OK. Go to step 3.

Replace the No. C2 (10 A) fuse, and recheck. If the fuse blows again, repair a short to ground on the No. C2 (10 A) fuse circuit, and recheck.

Open wire check (IG1 MISS SOL line)

-1. Jump the SCS line with the HDS.

-2. Disconnect the following connector.

PCM connector A (51P)

-3. Turn the vehicle to the ON mode.

-4. Measure the voltage between test points 1 and 2.

Test condition	Vehicle ON mode
	PCM connector A (51P): disconnected
Test circuit	IG1 MISS SOL
Test point 1	PCM connector A (51P) No. 1 (LT GRN)
Test point 2	Body ground

Is there battery voltage?

YES

The IG1 MISS SOL wire is OK. Go to step 4.

Repair an open in the IG1 MISS SOL wire between the PCM and the No. C2 (10 A) fuse in the under-hood fuse/relay box.

Determine possible failure area (short in LSA line, others)

-1. Turn the vehicle to the OFF (LOCK) mode.

-2. Reconnect PCM connector A (51P) .

-3. Jump the SCS line with the HDS.

-4. Disconnect the following connector.

PCM connector B (51P)

-5. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	PCM connector B (51P): disconnected
Test circuit	LSA
Test point 1	PCM connector B (51P) No. 6 (RED)
Test point 2	Body ground

Is there continuity?

YES

Go to step 5.

Go to step 6.

Shorted wire check (LSA line)

-1. Disconnect the following connector.

A/T clutch pressure control solenoid valve A 2P connector

-2. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	A/T clutch pressure control solenoid valve A 2P connector: disconnected
	PCM connector B (51P): disconnected
Test circuit	LSA
Test point 1	A/T clutch pressure control solenoid valve A 2P connector No. 2 (RED)
Test point 2	Body ground

Is there continuity?

YES

Repair a short to ground in the LSA wire between A/T clutch pressure control solenoid valve A and the PCM.

The LSA wire is OK. 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 (LSA line)

-1. Disconnect the following connector.

A/T clutch pressure control solenoid valve A 2P connector

-2. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	A/T clutch pressure control solenoid valve A 2P connector: disconnected
	PCM connector B (51P): disconnected
Test circuit	LSA
Test point 1	A/T clutch pressure control solenoid valve A 2P connector No. 2 (RED)
Test point 2	PCM connector B (51P) No. 6 (RED)

Is there continuity?

YES

The LSA wire is OK. Go to step 7.

Repair an open in the LSA wire between A/T clutch pressure control solenoid valve A and the PCM.

Open wire check (LSA PG line)

-1. Check for continuity between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	A/T clutch pressure control solenoid valve A 2P connector: disconnected
	PCM connector B (51P): disconnected
Test circuit	LSA PG
Test point 1	A/T clutch pressure control solenoid valve A 2P connector No. 1 (BLK)
Test point 2	Body ground

Is there continuity?

YES

The LSA PG wire is OK. Go to step 8.

Repair an open in the LSA PG wire between A/T clutch pressure control solenoid valve A and ground (G101) or repair poor ground (G101).

A/T clutch pressure control solenoid valve A check

-1. Measure the resistance between test points 1 and 2.

Test condition	Vehicle OFF (LOCK) mode
	A/T clutch pressure control solenoid valve A 2P connector: disconnected
	PCM connector B (51P): disconnected
Test circuit	LSA, LSA PG
