Resistance Check

Remove rear wheel speed sensor. See REAR WHEEL SPEED SENSOR  under REMOVAL & INSTALLATION. Measure resistance between sensor harness connector terminals. Wheel speed sensor resistance should be 1500-1900 ohms at 68°F (20°C). Measure resistance between each sensor harness connector terminal and wheel speed sensor body. Insulation resistance should be one megohm or greater. If either resistance test is not as specified, replace wheel speed sensor.
