Problem in A/T Clutch Pressure

Control Solenoid Valve A Circuit

NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-3) before
you troubleshoot.

• This code is caused by an electrical circuit problem

and cannot be caused by a mechanical problem in the
transmission.

1. Disconnect the A/T clutch pressure control solenoid

valve A connector.

2. Measure A/T clutch pressure control solenoid valve

A resistance at the solenoid valve connector
terminals.

Go to step 3.

Replace the A/T clutch pressure control

solenoid valve A.

3. Disconnect PCM connectors B (24P) and C (22P).

4. Check for continuity between PCM connector

terminals B14 and body ground, and between C1
and body ground.

Repair short to ground in the wires between

PCM connector terminals B14 and the A/T clutch
pressure control solenoid valve A, and between C1
and the A/T clutch pressure control solenoid valve
A.

Go to step 5.

5. Connect the A/T clutch pressure control solenoid

valve A connector.

6. Measure the resistance between the PCM

connector terminals B14 and C1.

Go to step 7.

Repair loose terminal or open in the wires

between PCM connector terminals B14 and the A/T
clutch pressure control solenoid valve A, and
between C1 and the A/T clutch pressure control
solenoid valve A.

7. Disconnect PCM connector A (31P).

8. Check for continuity between PCM connector

terminals A23 and body ground, and between A24
and body ground.

Update the PCM if it does not have the latest

software, or substitute a known-good PCM
(see page 14-7), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

Repair open in the wires between PCM

connector terminals A23 and ground (G101), and
between A24 and ground (G101), and repair poor
ground (G101).

14-103

Problem in Hydraulic Control

System of Shift Solenoid Valve A Circuit

NOTE: Record all freeze data and review General
Troubleshooting Information (see page 14-3) before
you troubleshoot.

1. Warm up the engine to normal operating

temperature (the radiator fan comes on).

2. Check to be sure that the transmission is filled to

the proper level, and check for fluid leaks.

3. Drain the ATF (see page 14-272) through a strainer.

Inspect the strainer for metal debris or excessive
clutch material.

Replace the transmission.

Replace the ATF (see page 14-272), then go to

step 4.

4. Reset the PCM memory by removing the No. 6 ECU

(15 A) fuse in the under-hood fuse/relay box for
more than 10 seconds (see page 14-6).

5. Start the engine, and shift to the M position. Start

the vehicle off in 1st, drive at 25 mph (40 km/h) for
10 seconds, shift to 2nd gear, drive at 25 mph
(40 km/h) for 10 seconds, then downshift to 1st gear,
and drive at 25 mph (40 km/h) for 10 seconds.

6. Recheck for DTC P0750.

Go to step 7.

The problem has been corrected.

7. Check whether the scan tool or the HDS indicates

another code.

Perform the troubleshooting for the indicated

code(s). Turn the ignition switch OFF, and go to
step 10 after troubleshooting.

Go to step 8.

8. Turn the ignition switch OFF.

9. Replace the shift solenoid valve A (see page

14-260).

10. Reset the PCM memory by removing the No. 6 ECU

(15 A) fuse in the under-hood fuse/relay box for
more than 10 seconds (see page 14-6).

11. Start the engine, and shift to M position. Start the

vehicle off in 1st, drive at 25 mph (40 km/h) for
10 seconds, shift to 2nd gear, drive at 25 mph
(40 km/h) for 10 seconds, then downshift to 1st gear,
and drive at 25 mph (40 km/h) for 10 seconds.

12. Recheck for DTC P0750.

Go to step 13.

The problem has been corrected.

13. Check for warranty coverage.

Replace the transmission assembly.

Go to step 14 or replace the transmission

assembly.

14. Turn the ignition switch OFF.

15. Remove the transmission, and overhaul

transmission hydraulic control system and the 2nd
clutch line.

16. Install the transmission on the vehicle.

17. Reset the PCM memory by removing the No. 6 ECU

(15 A) fuse in the under-hood fuse/relay box for
more than 10 seconds (see page 14-6), if necessary.

18. Start the engine, and shift to the M position. Start

19. Recheck for DTC P0750.
