DTC Advanced Diagnostics: P0501
DTC P0501:Output Shaft Speed Sensor Circuit Out of Range High

General Description
The powertrain control module (PCM) monitors the output speed sensor for electrical malfunctions. If the output shaft speed sensor outputs a specified value, the PCM detects a malfunction and stores a DTC.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the PCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC
The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
