Speed Sensor Circuit Continuity Check
WARNING: This page is about a different car, the 1992 Ford Probe. However, it is still accessible from the selected car via links, so may be relevant.
Turn ignition off. Set VOM to 200-ohm scale. Disconnect PRC control module (under passenger's seat) and instrument panel connector for analog or digital dash. Measure resistance between 2 Green/Red wires. If resistance reading is 5 ohms or more, repair open circuit in Green/Red wire. If resistance reading is less than 5 ohms, proceed to PINPOINT TEST A3.
