Front Speed Sensor
- Remove front wheel speed sensor from vehicle. See FRONT WHEEL SPEED SENSORS under REMOVAL & INSTALLATION. Using DVOM, measure resistance between speed sensor terminals. On Cressida, resistance should be 1200-1600 ohms. On Supra, resistance should be 800-1300 ohms.
- On all models, ensure continuity is not present between each sensor terminal and sensor body. If resistance and continuity readings are not as specified, replace speed sensor.
