DTC Troubleshooting: P0717 (15-3)

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


NOTE:

1.Clear the DTC in CLEAR MENU with the Honda PGM Tester or HDS.

2.Check for proper mainshaft speed sensor installation.

3.Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate freely.

4.Start the engine, drive the vehicle in the [D] position, and hold the vehicle at speeds over 30 mph (48 km/h) for more than 10 seconds. Slow down and stop the wheels.

5.Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0717.

Did the result fail?


YES - Go to 6.


NO - Intermittent failure, the system is OK at this time. If the tester indicates NOT COMPLETE, return to step 4 and recheck.n


6.Turn the ignition switch OFF.

7.Jump the SCS line with the Honda PGM Tester or HDS.

8.Disconnect PCM connector A (31P) and mainshaft speed sensor connector.

9.Check for continuity between PCM connector terminals A8 and body ground, and between A9 and body ground.

Is there continuity?


YES - Go to 10.


NO - Repair open in the wires between PCM connector terminals A8 and ground (G101), between A9 and ground (G101), and repair poor ground (G101).n


10.Connect PCM connector A (31P).

11.Turn the ignition switch ON (II).

12.Measure the voltage between No. 1 terminal of the mainshaft speed sensor connector and body ground.

Is there about 5 V?


YES - Go to 13.


NO - Go to 27.

13.Turn the ignition switch OFF.

14.Jump the SCS line with the Honda PGM Tester or HDS.

15.Disconnect PCM connector C (22P).

16.Check for continuity between the No. 2 terminal of the mainshaft speed sensor connector and body ground.

Is there continuity?


YES - Repair short to ground in the wire between PCM connector terminal C19 and mainshaft speed sensor connector.n


NO - Go to 17.


17.Check for continuity between the No. 3 terminal of the mainshaft speed sensor connector and body ground.

Is there continuity?


YES - Go to 18.


NO - Repair open in the wire between the mainshaft speed sensor connector and ground (G101).n

18.Reconnect PCM connectors C (22P), then turn the ignition switch ON (II).

19.Measure the voltage between the No. 2 and No. 3 terminals of the mainshaft speed sensor connector.

Is there about 5 V?


YES - Go to 20.


NO - Go to 32.


20.Connect the mainshaft speed sensor connector.

21.Measure the voltage between PCM connector terminals C19 and A8 or A9.

Is the voltage 0 V or about 5 V?


YES - Go to 22.


NO - Replace the  mainshaft speed sensor. After replacing the sensor, go to 24, and check that the repair has been completed.

22.Shift to the [P] position. Start the engine, and let it idle.

23.With the engine idling, measure the voltage between PCM connector terminals C19 and A8 or A9.

Is there 1.5 V-3.5 V?


YES - Update the PCM if it does not have the latest software, or substitute a known-good PCM , then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n


NO - Replace the  mainshaft speed sensor. After replacing the sensor, go to 24, and check that the repair has been completed.


24.Clear the DTC in CLEAR MENU with the Honda PGM Tester or HDS.

25.Test-drive the vehicle for several minutes under the same conditions as those indicated by the freeze data.

26.Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0717.

Did the result pass?


YES - The problem has been corrected.n


NO - Return to step 1 and recheck.n

27.Measure the voltage between PCM connector terminals A21 and A8 or A9.

Is there 4.75 V-5.25 V?


YES - Repair open in the wire between PCM connector terminal A21 and the mainshaft speed sensor connector.n


NO - Go to 28.


28.Turn the ignition switch OFF.

29.Jump the SCS line with the Honda PGM Tester or HDS.

30.Disconnect PCM connector A (31P).

31.Check for continuity between PCM connector terminal A21 and body ground.

Is there continuity?


YES - Repair short to ground in the wire between PCM connector terminal A21 and the mainshaft speed sensor connector.n


NO - Check for loose or poor connections at PCM connector terminal A21. If the connections are OK, update the PCM if it does not have the latest software, or substitute a known-good PCM , then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n

32.Measure the voltage between PCM connector terminals C19 and A8 or A9.

Is there about 5 V?


YES - Repair open in the wire between PCM connector terminal C19 and the mainshaft speed sensor connector.n


NO - Check for loose or poor connections at PCM connector terminal C19. If the connections are OK, update the PCM if it does not have the latest software, or substitute a known-good PCM , then recheck. If the symptom/indication goes away with a known-good PCM, replace the original PCM.n
