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.

Perform the Troubleshooting for the TP

sensor or the ECT sensor. Recheck for code P0715
after troubleshooting.

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.

Go to step 7.

Go to step 15.

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.

Repair short to ground in the wire between

PCM connector terminal D11 and the input shaft
(mainshaft) speed sensor.

Go to step 10.

Wire side of female terminals

Does the scan tool or the HDS indicate the code
f or the T P sensor or the ECT sensor ?

Is ther e about 5 V ?

Is ther e continuity?

and body ground.

Go to step 12.

Repair open in the wire between PCM

connector terminal D12 and the input shaft
(mainshaft) speed sensor.

12. Turn the ignition switch ON (II).

13. Measure the voltage between input shaft

(mainshaft) speed sensor connector terminals
No. 2 and No. 3.

Go to step 19.

Go to step 14.

14. Measure the voltage between PCM connector

terminals D11 and D12.

Repair open in the wire between PCM

connector terminal D11 and the input shaft
(mainshaft) speed sensor.

Check for loose terminal fit in the PCM

connectors D11, D12, and C28. If necessary,
substitute a known-good PCM and recheck only if
the code resets after being cleared.

Go to step 16.

16. Turn the ignition switch OFF.

17. Disconnect PCM connector C (31P).

18. Check for continuity between PCM connector

terminal C28 and body ground.

Repair short to ground in the wire between

PCM connector terminal C28 and the input shaft
(mainshaft) speed sensor.

Check for loose terminal fit in the PCM

connectors. If necessary, substitute a known-good
PCM and recheck only if the code resets after being
cleared.

19. Connect the input shaft (mainshaft) speed sensor

connector.

20. Measure the voltage between PCM Connector

terminals D11 and D12.

Go to step 21.

Replace the input shaft (mainshaft) speed

sensor (see page 14-364).

21. Start the engine, and run it at idle in P position.

22. Hold the engine at idle, and measure the voltage

between PCM connector terminals D11 and D12.

Check for loose terminal fit in the PCM

connectors D11, D12, and C28. Clear DTCs. If
necessary (only if the DTC recodes), substitute a
known-good PCM and recheck only if the DTC
recodes.

Replace the input shaft (mainshaft) speed

sensor (see page 14-364).
