Acura RL. Manual - part 238

INDICATED DTC'S TROUBLESHOOTING.

NO - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM. If the
PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ), then recheck. If
the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, return to step 11 and
recheck.

14. Connect the ATF temperature sensor connector.

15. Clear the DTC with the HDS.

16. Turn the ignition switch to ON (II), and wait for 20 seconds, then start the engine in P: Run the engine for

at least 10 seconds.

17. Check for DTC(s) in the DTCs/Freeze Data in A/T Mode Menu with the HDS.

Is DTC P0713 indicated?

YES - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then
go to step 1.

NO - Go to step 18.

18. Monitor the OBD STATUS for P0713 in the DTCs/Freeze Data in A/T Mode Menu for a pass/fail.

Does the HDS indicate PASSED?

YES - Troubleshooting is complete. If any other DTCs were indicated on step 17, go to the INDICATED
DTC'S TROUBLESHOOTING.

NO - Check for poor connections and loose terminals at the ATF temperature sensor and the PCM, then
go to step 1. If the HDS indicates NOT COMPLETED, return to step

and recheck.

DTC P0716: Problem in Input Shaft (Mainshaft) Speed Sensor Circuit; DTC P0717: Problem in Input Shaft (Mainshaft)
Speed Sensor Circuit (No Signal Input)

1. Clear the DTC with the HDS.

2. Check for proper input shaft (mainshaft) speed sensor installation (see INPUT SHAFT (MAINSHAFT)

SPEED SENSOR REPLACEMENT ). If the sensor is installed improperly, correct the problem, then
go to step 36.

3. Raise the vehicle on a lift, make sure it is securely supported, and allow the all four wheels to rotate

freely.

NOTE:



Before you troubleshoot, record all freeze data and any on-board
snapshot, and review General Troubleshooting Information (see GENERAL
TROUBLESHOOTING INFORMATION ).



This code is caused by an electrical circuit problem and cannot be caused
by a mechanical problem in the transmission.

4. Start the engine, and turn the VSA off (the light on the VSA OFF switch comes on). Run the vehicle in

either 2nd, 3rd, 4th, or 5th gear (not 1st) in M (sequential sportshift mode) at speeds over 12 mph (20
km/h) and an engine speed of 500 rpm or higher, for at least 10 seconds. Slow down and stop the wheels.

5. Monitor the OBD STATUS for P0716 or P0717 in the DTCs/Freeze Data in A/T Mode Menu for a

pass/fail.

Does the HDS indicate FAILED?

YES - Go to step 6.

NO - Intermittent failure, the system is OK at this time. Check for loose or poor connections at the PCM
and the input shaft (mainshaft) speed sensor connectors. If the HDS indicates NOT COMPLETED, return
to step 4 and recheck.

6. Turn the ignition switch to LOCK (0).

7. Jump the SCS line with the HDS.

8. Disconnect PCM connectors A (31P) and B (24P).

9. Check for continuity between PCM connector terminals A3 and body ground, and between B15 and body

ground.

Is there continuity?

YES - Go to step 10.

NO - Repair open in the wires between PCM connector terminals A3, B15, and ground (G101, G102), or
repair poor ground (G101, G102), then go to step 36.

10. Connect PCM connectors A (31P) and B (24P).

11. Disconnect the input shaft (mainshaft) speed sensor connector.

12. Turn the ignition switch to ON (II).

13. Measure the voltage between input shaft (mainshaft) speed sensor connector terminal No. 1 and body

Is there about 5 V?

YES - Go to step 14.

NO - Go to step 27.

14. Turn the ignition switch to LOCK (0).

15. Disconnect PCM connector D (17P).

16. Check for continuity between input shaft (mainshaft) speed sensor connector terminal No. 2 and body

ground.

Is there continuity?

YES - Repair short in the wire between PCM connector terminal D8 and the input shaft (mainshaft) speed
sensor connector, then go to step 36.

NO - Go to step 17.

17. Disconnect PCM connector C (22P).

18. Check for continuity between PCM connector terminal C12 and input shaft (mainshaft) speed sensor

connector terminal No. 3.

Is there continuity?

YES - Go to step 19.

NO - Repair open in the wire between the input shaft (mainshaft) speed sensor connector and PCM
connector terminal C12, then go to step 36.

19. Connect PCM connectors C (22P) and D (17P).

20. Turn the ignition switch to ON (II).

21. Measure the voltage between input shaft (mainshaft) speed sensor connector terminals No. 2 and No. 3.
