DTC P0717: PROBLEM IN INPUT SHAFT (MAINSHAFT) SPEED SENSOR CIRCUIT (NO SIGNAL 
INPUT) 

Fig. 99: Input Shaft (Mainshaft) Speed Sensor Circuit Diagram 

Fig. 100: Vehicle Speed Graph 

General Description 

The input shaft (mainshaft) speed sensor is attached to the outside of the transmission housing. The input shaft 
(mainshaft) speed sensor generates a pulsing signal according to the speed of the input shaft (mainshaft) idler 
gear on the input shaft (mainshaft). Using that signal, the powertrain control module (PCM) determines the 
speed of the input shaft (mainshaft). If no pulses occur with the input shaft (mainshaft) rotating, the PCM 
detects a malfunction that may be caused by an open, a temporary open, or a short to ground. Based on the 
correlation between the vehicle speed measured by the output shaft (countershaft) speed sensor and the input 
shaft (mainshaft) speed sensor, a malfunction is detected and a DTC is stored.

Enable Conditions 

ENABLE CONDITIONS 

Malfunction Threshold 

When the vehicle speed measured by the output shaft (countershaft) speed sensor is 13 mph (20 km/h) or more, 
the vehicle speed measured by the input shaft (mainshaft) speed sensor is 1 mph (2 km/h) or less for at least 10 
seconds. 

Driving Pattern 

Start the engine, and drive the vehicle at a speed of 13 mph (20 km/h) or more for at least 10 seconds. 



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.  

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected, the MIL comes on and the DTC and the freeze frame data are stored in the 
PCM memory. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic 
runs.

DTC P0718: INPUT SHAFT (MAINSHAFT) SPEED SENSOR INTERMITTENT FAILURE

General Description 

The input shaft (mainshaft) speed sensor is attached to the outside of the transmission housing. The input shaft 
(mainshaft) speed sensor generates a pulsing signal according to the speed of the input shaft (mainshaft) idler 
gear on the input shaft (mainshaft). Using that signal, the powertrain control module (PCM) determines the 
speed of the input shaft (mainshaft). If no pulses occur with the input shaft (mainshaft) rotating, the PCM 
detects a malfunction that may be caused by an open, a temporary open, or a short to ground. Based on the 
fluctuation of the vehicle speed measured by the input shaft (mainshaft) speed sensor, a malfunction is detected 
and a DTC is stored.

MONITOR DESCRIPTION 

Enable Conditions 

ENABLE CONDITIONS 

Malfunction Threshold 

The fluctuation of the vehicle speed measured by the input shaft (mainshaft) speed sensor in 10 milliseconds is 
4 mph (6km/h) or more, and it fluctuates at least six times within 500 milliseconds. 

Driving Pattern 

Start the engine, and drive the vehicle at a speed of 13 mph (20 km/h) or more so it shifts from 1st to 5th in D 
position. 



Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.  

Diagnosis Details 

Conditions for illuminating the MIL 

When a malfunction is detected during the first drive cycle, a Temporary DTC is stored in the PCM memory. If 
the malfunction recurs during the next (second) drive cycle, the MIL comes on and the DTC and the freeze 
frame data are stored. 

Conditions for clearing the MIL 

The MIL will be cleared if the malfunction does not recur during three consecutive trips in which the diagnostic 
runs. 

The MIL, the DTC, the Temporary DTC, and the freeze frame data can be cleared by using the scan tool Clear 
command or by disconnecting the battery.
