DTC P0500: Notes
DTC P0500 [AJ] DETECTION CONDITION AND POSSIBLE CAUSES
| DTC P0500 |
VSS circuit malfunction |
| DETECTION CONDITION |
With ABS/TCS
- If an error in the wheel speed signal from the ABS/TCS HU/CM is detected by CAN when the following conditions are met, the PCM detects a malfunction in the vehicle speed signal.
- In a shift range other than P, N or R position (ATX).
- The neutral switch and clutch pedal position switch are OFF (MTX).
- The load is 40% or above.
- The engine speed is 2,000 RPM or above.
- Brake switch is off
MTX without ABS/TCS
- The vehicle speed signal from the vehicle speed sensor is 3.7 km/h {2.3 mph} or below
when the following conditions are met:
- The neutral switch and clutch pedal position switch are OFF.
- The load is 40% or above.
- The engine speed is 2,000 RPM or above.
- Brake switch is off
Diagnostic support note
- This is a continuous monitor (CCM).
- MIL illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
- PENDING CODE is available if the PCM detects the above malfunction condition during the first drive cycle.
- FREEZE FRAME DATA is available.
- DTC is stored in PCM memory.
