Speed Sensor (Exc. Electronic Speedometer)

Disconnect speed sensor connector and connect an ohmmeter between wire connector terminals (Dk Grn/White stripe and Black) at speed sensor end. A reading of 30-100 ohms (40 ohms for Escort and Lynx) should be obtained. A reading of 0 ohms indicates a shorted coil, and a high reading indicates an open coil. If reading is within proper range and speedometer operates properly, sensor is probably good. Substitute a new sensor if necessary to check operation.
