DTC Troubleshooting: P0722 (35)
DTC P0722:
Problem in CVT Output Shaft (Driven Pulley) Speed Sensor Circuit (No Signal Input)
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information How To Troubleshoot The CVT System.
- This code is sometimes caused by an electrical circuit problem and sometimes caused by a broken steel belt in the transmission.
1. Check for proper CVT output shaft (driven pulley) speed sensor installation CVT Output Shaft (Driven Pulley) Speed Sensor Replacement. If the sensor is installed incorrectly, reinstall the sensor correctly, then go to step 22.
2. Turn the ignition switch to ON (II).
3. Clear the DTC with the HDS.
4. Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported, and allow the front wheels to rotate freely.
5. Start the engine, disable the VSA by pressing the VSA OFF button, run the vehicle with the shift lever in D, and the engine speed at 3,500 rpm or higher, for at least 30 seconds. Slow down and stop the wheels.
6. Monitor the OBD STATUS for P0722 in the DTCs MENU with the HDS.
Does the HDS indicate FAILED?
YES -
Go to step 7.
NO -
If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the CVT output shaft (driven pulley) speed sensor and the PCM. If the HDS indicates NOT COMPLETED, go to step 5.
7. Turn the ignition switch to LOCK (0).
8. Disconnect the CVT output shaft (driven pulley) speed sensor 3P connector.
9. Turn the ignition switch to ON (II).
10. Measure the voltage between CVT output shaft (driven pulley) speed sensor 3P connector terminal No. 1 and body ground.
Is there about 5 V?
YES -
Go to step 15.
NO -
Go to step 11.
11. Turn the ignition switch to LOCK (0).
12. Jump the SCS line with the HDS.
13. Disconnect PCM connector C (49P).
14. Check for continuity between PCM connector terminal C13 and CVT output shaft (driven pulley) speed sensor 3P connector terminal No. 1.
Is there continuity?
YES -
Go to step 28.
NO -
Repair an open in the wire between PCM connector terminal C13 and the CVT output shaft (driven pulley) speed sensor 3P connector, then go to step 22.
15. Measure the voltage between CVT output shaft (driven pulley) speed sensor 3P connector terminals No. 2 and No. 3.
Is there about 5 V?
YES -
Replace the CVT output shaft (driven pulley) speed sensor CVT Output Shaft (Driven Pulley) Speed Sensor Replacement, then go to step 22.
NO -
Go to step 16.
16. Turn the ignition switch to LOCK (0).
17. Jump the SCS line with the HDS.
18. Disconnect PCM connector B (49P).
19. Check for continuity between CVT output shaft (driven pulley) speed sensor 3P connector terminal No. 2 and body ground.
Is there continuity?
YES -
Repair a short in the wire between PCM connector terminal B44 and the CVT output shaft (driven pulley) speed sensor 3P connector, then go to step 22.
NO -
Go to step 20.
20. Check for continuity between PCM connector terminal C14 and CVT output shaft (driven pulley) speed sensor 3P connector terminal No. 3.
Is there continuity?
YES -
Go to step 21.
NO -
Repair an open in the wire between PCM connector terminal C14 and the CVT output shaft (driven pulley) speed sensor 3P connector, then go to step 22.
21. Check for continuity between PCM connector terminal B44 and CVT output shaft (driven pulley) speed sensor 3P connector terminal No. 2.
Is there continuity?
YES -
Go to step 28.
NO -
Repair an open in the wire between PCM connector terminal B44 and the CVT output shaft (driven pulley) speed sensor 3P connector, then go to step 22.
22. Reconnect all connectors.
23. Turn the ignition switch to ON (II).
24. Clear the DTC with the HDS.
25. Start the engine, disable the VSA by pressing the VSA OFF button, run the vehicle with the shift lever in D, and the engine speed at 3,500 rpm or higher, for at least 30 seconds. Slow down and stop the wheels.
26. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0722 indicated?
YES -
Check for poor connections or loose terminals between the CVT output shaft (driven pulley) speed sensor and the PCM, then go to step 1.
NO -
Go to step 27.
27. Monitor the OBD STATUS for P0722 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES -
Troubleshooting is complete. If any other Pending or Confirmed DTCs were indicated in step 26, go to the indicated DTC's troubleshooting.
NO -
If the HDS indicates FAILED, check for poor connections or loose terminals between the CVT output shaft (driven pulley) speed sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 25.
28. Reconnect all connectors.
29. Update the PCM if it does not have the latest software PCM Update, or substitute a known-good PCM.
30. Start the engine, disable the VSA by pressing the VSA OFF button, run the vehicle with the shift lever in D, and the engine speed at 3,500 rpm or higher, for at least 30 seconds. Slow down and stop the wheels.
31. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0722 indicated?
YES -
Check for poor connections or loose terminals between the CVT output shaft (driven pulley) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 30. If the PCM was substituted, go to step 1.
NO -
Go to step 32.
32. Monitor the OBD STATUS for P0722 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES -
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM Service and Repair. If any other Pending or Confirmed DTCs were indicated in step 31, go to the indicated DTC's troubleshooting.
NO -
If the HDS indicates FAILED, check for poor connections or loose terminals between the CVT output shaft (driven pulley) speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 30. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 30.
