DTC P0500 VEHICLE SPEED SENSOR MTR

Description
The vehicle speed sensor-MTR signal is transmitted from unified meter and A/C amp. to TCM by CAN communication line. The signal functions as an auxiliary device to the revolution sensor when it is malfunctioning. The TCM will then use the vehicle speed sensor-MTR signal.

On Board Diagnosis Logic
- This is not an OBD-II self-diagnostic item.
- Diagnostic trouble code "VEH SPD SE/CIR-MTR" with CONSULT-II or 15th judgement flicker without CONSULT-II is detected when TCM does not receive the proper vehicle speed sensor MTR signal (input by CAN communication) from unified meter and A/C amp.

Possible Cause
- Harness or connectors (The signal circuit is open or shorted.)
- Unified meter and A/C amp.
- ABS actuator and electric unit (control unit)
- Wheel sensor
