Problem verification:

Problem verification
?1.
Turn the vehicle to the ON mode.

?2.
Clear the DTC with the HDS.


?3.
Raise the vehicle on a lift. Make sure it is securely supported, and allow all four wheels to rotate freely.

?4.
Start the engine.

?5.
Disable the VSA by pressing the VSA OFF button.

NOTE: Enter the VSA maintenance mode in case of the vehicle speed above 31 mph (50 km/h).

?6.
Test-drive the vehicle in D position/mode, and keep the vehicle at speeds over 19 mph (30 km/h) for at least 30 seconds. Slow down and stop the wheels.

?7.
Check for Pending or Confirmed DTCs with the HDS.

Is DTC P0792 indicated?

     
YES
     
     
     
The failure is duplicated. Go to step 2.
     
NO
     
     
     
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the PCM and the CVT drive pulley speed sensor. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.?
2.
CVT drive pulley speed sensor check:

CVT drive pulley speed sensor check
?1.
Rotate the front wheels in D position/mode, while monitoring the Input Shaft (Drive Pulley) Speed rpm and the Torque Converter Turbine Speed rpm in the Data List with the HDS.

?2.
Compare the parameters below with the HDS.

Are the speeds about the same?

     
YES
     
     
     
The CVT drive pulley speed sensor is OK. Update the PCM if it does not have the latest software, or substitute a known-good PCM, then recheck. If DTC P0792 goes away and the PCM was updated, troubleshooting is complete. If DTC P0792 goes away and the PCM was substituted, replace the original PCM.?
