DTC P0718: Input Shaft (Mainshaft) Speed
Sensor Intermittent Failure
NOTE:
• Before you troubleshoot, record all freeze data and
any on-board snapshot with the HDS, and review
General Troubleshooting Information (see page 14-4).
• 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 to ON (II).
2. Clear the DTC with the HDS.
3. Test-drive the vehicle at speeds over 12 mph
(20 km/h) with the shift lever in D, and let the
transmission shift through all five gears.
4. Monitor the OBD STATUS for P0718 in the DTCs
MENU with the HDS.
Does the HDS indicate F AILED?
YES − Go to step 5.
−
NO If the HDS indicates PASSED, intermittent
failure, the system is OK at this time. Check for
poor connections or loose terminals between the
input shaft (mainshaft) speed sensor and the PCM.
If the HDS indicates NOT COMPLETED, go to step 3.
5. Turn the ignition switch to LOCK (0).
6. Disconnect the input shaft (mainshaft) speed
sensor connector, and inspect the connector and
connector terminals to be sure they are making
good contact.
Are the connector terminals OK ?
YES − Go to step 7.
−
NO Repair the connector terminals, then go to
step 7.
7. Connect the input shaft (mainshaft) speed sensor
connector.
8. Test-drive the vehicle at speeds over 12 mph
(20 km/h) with the shift lever in D, and let the
transmission shift through all five gears.
9. Monitor the OBD STATUS for P0718 in the DTCs
MENU with the HDS.
Does the HDS indicate F AILED?
