A/T Clutch Pressure Control

Solenoid Valve C Stuck OFF

NOTE: Record all freeze data and review General
Troubleshooting Information (see page 14-8) before
you troubleshoot.

1. Warm up the engine to normal operating

temperature (the radiator fan comes on).

2. Make sure that the transmission is filled to the

proper level, and check for fluid leaks.

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

strainer. Inspect the strainer for metal debris or
excessive clutch material.

Replace the transmission.

Replace the ATF (see step 4 on page 14-272)

then go to step 4.

4. Clear the DTC with the HDS.

5. Test-drive the vehicle in the D position through all

five gears at speeds over 12 mph (20 km/h) for
more than 20 seconds, then slow down to a stop.

6. Retest-drive the vehicle in the D position through

all five gears at speeds over 12 mph (20 km/h) for
more than 20 seconds, then slow down to a stop.

7. Monitor the OBD status for P0796 in the DTCs/

Freeze Data in A/T Mode Menu for a pass/fail.

Go to step 8.

Intermittent failure, the system is OK at this

time. If the tester indicates NOT COMPLETED,
return to step 5 and recheck.

8. Clear the DTC with the HDS.

9. Choose Clutch Pressure Control (Linear) Solenoid C

in Miscellaneous Test Menu, and test the A/T clutch
pressure control solenoid valve C with the HDS.

Intermittent failure, the system is OK at this

time. If the tester indicates NOT COMPLETED,
return to step 9 and recheck.

Follow the instructions indicated on the HDS

by the tester result, but if the tester has not
determined the cause of the failure, go to step 10. If
any part was replaced, go to step 11.

10. Inspect A/T clutch pressure control solenoid valve

C (see page 14-264).

Repair hydraulic system related with shift

valve B and C, or replace the transmission, then go
to step 11.

Replace A/T clutch pressure control solenoid

valve C (see page 14-265), then go to step 11.

11. Clear the DTC with the HDS.

12. Test-drive the vehicle in the D position through all

five gears at speeds over 12 mph (20 km/h) for
more than 20 seconds, then slow down to a stop.

13. Retest-drive the vehicle in the D position through

all five gears at speeds over 12 mph (20 km/h) for
more than 20 seconds, then slow down to a stop.

14. Monitor the OBD status for P0796 in the DTCs/

Freeze Data in A/T Mode Menu for a pass/fail.

Troubleshooting is completed.

Return to step 8 and recheck.

Does the str ainer contain metal debr is or
excessive clutch mater ial?

Does the r esult indicate a f ailed?

PCM CONNECTOR A (31P)

LG1 (BRN/YEL)

LG2 (BRN/YEL)

Open in Transmission Range

Switch ATP RVS Switch Circuit

NOTE:

• Record all freeze data and review General

Troubleshooting Information (see page 14-8) before
you troubleshoot.

• This code is caused by an electrical circuit problem

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

1. Turn the ignition switch ON (II).

2. Shift to the R position, and verify the A/T R SWITCH

signal with the HDS in the A/T data list.

Go to step 3.

Inspect the end of the selector control shaft

(see step 6 on page 14-308), adjust the shift cable
(see page 14-299), then recheck. If problem still
exists, go to step 4.

3. Check the REVERSE SWITCH signal with the HDS.

Intermittent failure, the system is OK at this

time. Check for poor connections or loose terminals
at the transmission range switch and PCM.

Go to step 4.

4. Turn the ignition switch OFF.

5. Check for continuity between PCM connector

terminals A8 and body ground, and between A9
and body ground.

Go to step 6.

Repair open in the wires between PCM

connector terminals A8, A9, and ground (G101),
and repair poor ground (G101), then go to step 12.

6. Turn the ignition switch ON (II).

7. Shift to the R position.

8. Measure the voltage between PCM connector

terminals C12 and A9.

Go to step 9.

Check for loose or poor connections at PCM

connector terminal C12. If the connection is OK,
update the PCM if it does not have the latest
software, or substitute a known-good PCM
(see page 14-11), then recheck. If the symptom/
indication goes away with a known-good PCM,
replace the original PCM.

9. Turn the ignition switch OFF.

10. Disconnect the transmission range switch

connector.

11. Check for continuity between transmission range

switch connector terminals No. 1 and No. 10. The
shift position must be the R position.

Check for loose or poor connections at the

transmission range switch connector terminal
No. 1. If the connection is OK, repair open in the
wire between PCM connector terminal C12 and the
transmission range switch, then go to step 12.

Replace the transmission range switch, then

go to step 12.

12. Clear the DTC with the HDS.

13. Start the engine, and shift the shift lever slowly into

the P, R, then N position.

14. Monitor the OBD status for P0812 in the DTCs/

Freeze Data in A/T Mode Menu for a pass/fail.

Troubleshooting is completed.

Return to step 1 and recheck.
