DTC P0501: Vehicle Speed Sensor Range/Performance: DTC Detecting Condition
- DTC Description
The ECM evaluates engine speed and mass air flow if there is no vehicle speed signal. This evaluation of both value will detect open circuit or short circuit error on wheel speed sensor. The ECM sets DTC P0501 if there is no vehicle speed signal from wheel speed sensor while both engine speed and mass air flow are higher than predetermined threshold during predetermined time.
If the same error code is set in the next driving cycle, the ECM illuminates the MIL.
