MX-5 Miata L4-1.8L DOHC (1996)
Wheel Speed Sensor: Testing and Inspection
1. Measure clearance between wheel speed sensor and rotor; clearance should be as 0.012 - 0.043 inch. If not, replace sensor or rotor as necessary.
2. Disconnect wheel speed sensor electrical connector and measure resistance between terminals. Resistance should be 0.8 - 1.2 kohms.
3. Raise and support vehicle; then, with wheel speed sensor connector disconnected, measure voltage at each sensor with corresponding wheel
rotating at one revolution per second. Voltage should be .25 - 1.2 volts.
4. If results are not as specified, replace wheel speed sensor or rotor as necessary.
