Is there about 5 V?

YES -Repair open in the wire between PCM connector terminal C19 and the input shaft (mainshaft)
speed sensor, then go to step 30.

NO -Go to step 36.

30. Reconnect all connectors.

31. Turn the ignition switch ON (II).

32. Clear the DTC with the HDS.

33. Start the engine, disable the VSA by pressing the VSA OFF switch, run the vehicle in the D position and

hold the vehicle at speeds over 12 mph (20 km/h) for at least 10 seconds. Slow down and stop the wheels.

34. Check for DTCs with the HDS.

Is DTC P0716 or P0717 indicated?

YES -Check for poor connections or loose terminals between the input shaft (mainshaft) speed sensor and
the PCM, then go to step 1.

NO -Go to step 35.

35. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -Troubleshooting is complete. If any other DTCs were indicated in step 34, go to the indicated

DTCs troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the input
shaft (mainshaft) speed sensor and the PCM, then go to step 1. If the screen indicates NOT
COMPLETED, go to step 33.

36. Update the PCM if it does not have the latest software (see UPDATING THE PCM ), or substitute a

known-good PCM (see SUBSTITUTING THE PCM ).

37. Start the engine, disable the VSA by pressing the VSA OFF switch, run the vehicle in the D position and

hold the vehicle at speeds over 12 mph (20 km/h) for at least 10 seconds. Slow down and stop the wheels.

38. Check for DTCs with the HDS.

Is DTC P0716 or P0717 indicated?

YES -Check for poor connections or loose terminals between the input shaft (mainshaft) speed sensor and
the PCM. If the PCM was updated, substitute a known-good PCM (see SUBSTITUTING THE PCM ),
then go to step 37. If the PCM was substituted, go to step 1.

NO -Go to step 39.

39. Monitor the OBD STATUS for P0716 or P0717 in the DTCs MENU with the HDS.

Does the screen indicate PASSED?

YES -If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the
original PCM (see ECM/PCM REPLACEMENT ). If any other DTCs were indicated in step 38, go to
the indicated DTCs troubleshooting.

NO -If the screen indicates FAILED, check for poor connections or loose terminals between the input
shaft (mainshaft) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM (see
SUBSTITUTING THE PCM ), then go to step 37. If the PCM was substituted, go to step 1. If the
screen indicates NOT COMPLETED, go to step 37.

1. Turn the ignition switch ON (II).

2. Clear the DTC with the HDS.

3. Test-drive the vehicle at speeds over 12 mph (20 km/h) in the D position through all five gears.

4. Turn the ignition switch OFF, and repeat the test-drive in step 3.

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.
