DTC P0500-31: Vehicle Speed Sensor "A" No Signal [06/2018 - 11/2022]: Description
WARNING: This page is about a different variant/trim than selected.
Vehicles which are equipped with ABS (Anti-lock Brake System) detect the vehicle speed using the skid control ECU (brake actuator assembly) and wheel speed sensors. Each wheel speed sensor monitors the wheel rotation speed and sends a signal to the skid control ECU. The skid control ECU converts the wheel speed signals into a 4-pulse signal and transmits it to the TCM via the combination meter assembly. The TCM determines the vehicle speed based on the frequency of the pulse signal.
HINT:
- Various systems use the vehicle speed signal distributed from the combination meter assembly. Check all the components possibly related to the speed signal.
- A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter assembly. The signal is changed to a pulse signal at the transistor in the combination meter assembly. Each ECU controls the respective system based on the pulse signal.
- If a short occurs in any of the ECUs or in the wire harness connected to an ECU, all systems using the speed signal will not operate normally.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P0500-31 | Vehicle Speed Sensor "A" No Signal | When the speed indicated by transmission revolution sensor (NOUT) and (NSS) are 380 rpm or more, no vehicle speed sensor signal is received by the TCM for 5 seconds or more (1-trip detection logic). |
