Code 37

Right rear speed sensor failure. ABS ECU recognized speed sensor failure by monitoring of wheel speed continuity with vehicle speed more than 25 MPH. Failure can be caused by an intermittently opened or shorted speed sensor coil or speed sensor wire, damaged teeth on sensor wheel, too large a wheel bearing gap or incorrect speed sensor installation. Check sensor wire terminals for a short or open circuit. Check toothed sensor ring for warping, speed sensor installation and bearing clearance.
