Toyota Camry (XV70): Right Front Wheel Speed Sensor Circuit Short to Battery (C050612)
DESCRIPTION
Each speed sensor detects wheel speed and sends signals to the skid control ECU (brake actuator assembly). These signals are used by the ABS control.
The speed sensor detects the magnetic fields of the speed sensor rotor as it rotates and outputs a pulse signal.
The frequency of the pulse varies in accordance with the rotational speed of the speed sensor rotor and the system uses this to determine the wheel speed.

PROCEDURE
|
1. | CHECK HARNESS AND CONNECTOR (SENSOR GROUND CIRCUIT) |
| (a) Make sure that there is no looseness at the locking part and the connecting part of the connectors. OK: The connector is securely connected. |
|
(b) Disconnect the A35 front speed sensor RH connector.
(c) Check both the connector case and the terminals for deformation and corrosion.
OK:
No deformation or corrosion.
(d) Turn the ignition switch to ON.
(e) Measure the voltage according to the value(s) in the table below.
Standard Voltage:

Tester Connection | Condition |
Specified Condition |
|---|---|---|
|
A35-1 (FR+) - A35-2 (FR-) |
Ignition switch ON | 11 to 14 V |
| OK | .gif) | REPLACE FRONT SPEED SENSOR RH |
