& No. 7
 

7. Measure the voltage between PCM connector terminal C14 and body ground. 

Is there about 5 V? 

YES: Repair open in the wire between PCM connector terminal C14 and the shift solenoid 
harness connector, then go to step 8.  

NO: Check for loose or poor connections at PCM connector terminal C14. If the connection 
is OK, update the PCM if it does not have the latest software, or substitute a known-good 
PCM (see PCM UPDATING & SUBSTITUTION FOR TESTING ), then recheck. If the 
symptom/indication goes away with a known-good PCM, replace the original PCM.

NO: Return to step 1 and recheck.  

DTC P0716: PROBLEM IN MAINSHAFT SPEED SENSOR CIRCUIT 

1. Record all freez data, then clear the DTC with the HDS.  

2. Check for proper mainshaft speed sensor installation (see MAINSHAFT SPEED SENSOR 

REPLACEMENT ).  

3. Raise the front of the vehicle, make sure it is securely supported, and allow the front wheels to rotate 

freely.  

4. Start the engine, drive the vehicle in the position, and hold the vehicle at speeds over 30 mph (48 km/h) 

for more than 10 seconds.  

5. Check the OBD STATUS in DTCs MENU for a pass/fail test of code P0716. 

Did the result indicate a fail? 

YES: Go to step 6.  

NO: Intermittent failure, the system is OK at this time. If the tester indicates NOT 
COMPLETE, return to step 4 and recheck.  

6. Turn the ignition switch OFF.  

7. Jump the SCS line with the HDS.  

8. Disconnect PCM connector A (31P) and mainshaft speed sensor connector.  

9. Check for continuity between PCM connector terminals A8 and body ground, and between A9 and body 

ground. 

Is there continuity? 

YES: Go to step 10.  

NO: Repair open in the wires between PCM connector terminals A8, A9 and ground (G 
101), or repair poor ground (G101), then go to step 30 . 

NOTE:
