DTC Troubleshooting

DTC P0501: Range/Performance Problem in CVT Speed Sensor Circuit

NOTE:
^ Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information.
^ This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

1. Turn the ignition switch to ON (II).
2. Clear the DTC with the HDS.
3. Start the engine, run the vehicle with the shift lever in L, and the engine speed at 4,500 rpm or higher, then release the accelerator without pressing it again, for at least 6 seconds.
4. Monitor the OBD STATUS for P0501 in the DTCs MENU with the HDS.

Does the HDS indicate FAILED?

YES - Replace the CVT speed sensor, then go to step 5.

NO - If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals between the PCM and the CVT speed sensor. If the HDS indicates NOT COMPLETED, go to step 3.

5. Turn the ignition switch to ON (II).
6. Clear the DTC with the HDS.
7. Start the engine, run the vehicle with the shift lever in D, and keep the vehicle at speeds over 24 mph (40 km/h) while monitoring the Output shaft (Driven pulley) Speed rpm in the Data list with the HDS, then release the accelerator without pressing it again, for at least 7 seconds.
8. Check for DTC with the HDS.

Is DTC P0501 indicated?

YES - Check for poor connections or loose terminals between the CVT speed sensor and the PCM, then go to step 10.

NO - Go to step 9.

9. Monitor the OBD STATUS for P0501 in the DTCs MENU with the HDS.

Does the HDS indicate PASSED?

YES - Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in step 8, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the CVT speed sensor and the PCM, then go to step 1. If the HDS indicates NOT COMPLETED, go to step 7.

10. Update the PCM if it does not have the latest software, or substitute a known-good PCM.
11. Start the engine, run the vehicle with the shift lever in D, and keep the vehicle at speeds over 24 mph (40 km/h) while monitoring the Output shaft (Driven pulley) Speed rpm in the Data list with the HDS, then release the accelerator without pressing it again, for at least 7 seconds.
12. Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0501 indicated?

YES - Check for poor connections or loose terminals between the CVT speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 11. If the PCM was substituted, go to step 1.

NO - Go to step 13.

13. Monitor the OBD STATUS for P0501 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. If any other Temporary DTCs or DTCs were indicated in step 12, go to the indicated DTC's troubleshooting.

NO - If the HDS indicates FAILED, check for poor connections or loose terminals between the CVT speed sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to step 11. If the PCM was substituted, go to step 1. If the HDS indicates NOT COMPLETED, go to step 11.
