DTC P0501: CVT Speed Sensor Circuit Range / Performance
NOTE:
- Before you troubleshoot, review the General Troubleshooting Information - Refer to: HOW TO TROUBLESHOOT THE FUEL AND EMISSIONS SYSTEMS or How to Troubleshoot the CVT System(CVT) .
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.

| P0501 CVT Speed Sensor Circuit Range/Performance |
DTC (CVT)
- Problem verification:
- 1. Turn the vehicle to the ON mode.
- 2. Clear the DTC with the HDS.
- 3. Turn the vehicle to the OFF (LOCK) mode.
- 4. Raise the vehicle on a lift. Make sure it is securely supported, and allow all four wheels to rotate freely.
- 5. Enter the VSA maintenance mode (with VSA).
- 6. Test-drive the vehicle at a speed of 37 mph (60 km/h) or more.
- 7. Release the accelerator pedal, then slow down, and stop the wheels.
- 8. Check for Pending or Confirmed DTCs with the HDS.
DTC Description Confirmed DTC Pending DTC Freeze Frame P0501 CVT Speed Sensor Circuit Range/Performance Is DTC P0501 indicated?
YES
The failure is duplicated. Go to step 2.
NO
Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between the CVT speed sensor and the PCM. 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.
- CVT speed sensor check:
- 1. Rotate the front wheels with the shift lever in D position/mode, and compare the Secondary Shaft Speed 1 (rpm) and the Input Shaft(Drive Pulley) Speed rpm in the Data List with the HDS.
Signal Current conditions Values Unit Secondary Shaft Speed 1 (rpm) Input Shaft(Drive Pulley) Speed rpm Are the speeds about the same?
YES
The CVT 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 P0501 goes away and the PCM was updated, troubleshooting is complete. If DTC P0501 goes away and the PCM was substituted, replace the original PCM .
NO
