DESCRIPTION
The vehicle speed sensors detect the wheel speed and send the appropriate signals to the skid control ECU. The skid control ECU converts these wheel speed signals into a 4-pulse signal and outputs it to the ECM via the combination meter assembly. The ECM determines the vehicle speed based on the frequency of these pulse signals.

WIRING DIAGRAM
Refer to SFI System (for 1AR-FE) (See page
).
Refer to SFI System (for 2GR-FE) (See page
).
CAUTION / NOTICE / HINT
This DTC may be output by the SFI system at the same time. In that case, perform troubleshooting for the SFI system first.
PROCEDURE

1. |
READ OUTPUT DTC (DTC P0500) |
(a) Clear the DTCs (See page
).
(b) Perform the following to make sure that the DTC detection conditions are met.
HINT:
If the detection conditions are not met, the malfunction cannot be detected.
(1) With the shift lever in D, drive the vehicle for more than 10 seconds when the engine coolant temperature is more than 20°C (68°F).
(c) Check for DTCs (See page
).

Vehicle Speed Sensor Malfunction (B2283)
DESCRIPTION
The skid control ECU converts wheel speed sensor signals into 4-pulse signals
and sends them to the combination meter. After this signal is converted into a more
precise rectangular waveform by the waveform shaping circuit inside the combinati ...
