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.?
2.
CVT speed sensor check:

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.

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.?
