DTC P0715: A Problem in Input Shaft
(Mainshaft) Speed Sensor Circuit
NOTE: Record all freeze data and review General
Troubleshooting Information (see page 14-247) before
you troubleshoot.
Code P0715 (code 15) doesn't always mean there's an
electrical problem in the input shaft (mainshaft) or
output shaft (countershaft) speed sensor circuit; code
P0715 (code 15) may also indicate a mechanical
problem in the transmission. Any problem causing
irregular countershaft-to-mainshaft speed difference
can cause this code.
A mainshaft speed of 0 mph ( km/h) in the freeze data
usually means there is an electrical problem in the input
shaft (mainshaft) speed sensor circuit. A mainshaft
speed that is higher or lower than countershaft and
vehicle speed sensor usually means a hydraulic system
problem caused the DTC.
1. Turn the ignition switch ON (II).
2. Check whether the scan tool or the HDS indicates
the code for the throttle position (TP) sensor or the
engine coolant temperature (ECT) sensor.
Does the scan tool or the HDS indicate the code
f or the T P sensor or the ECT sensor?
YES Perform the Troubleshooting for the TP
sensor or the ECT sensor. Recheck for code P0715
after troubleshooting.
NO Go to step 3.
3. Turn the ignition switch OFF.
4. Disconnect the input shaft (mainshaft) speed
sensor connector.
5. Turn the ignition switch ON (II).

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

7. Turn the ignition switch OFF.
8. Disconnect PCM connector D (16P).
9. Check for continuity between input shaft
(mainshaft) speed sensor connector terminal No. 2
and body ground.
