Speed Sensor
- Raise and support front of vehicle. Set parking brake and block rear wheels. Connect voltmeter positive lead or test light to Yellow/Black wire at control box connector. Connect negative lead to ground.
- Start engine. Shift transmission into 2nd gear and accelerate slowly, while observing voltmeter. Voltmeter should read battery voltage below 6 MPH and no voltage above 12 MPH.
- If voltmeter readings are not as specified, install new speed sensor and retest. If there is no voltage during speed sensor test, check for bad connection, faulty wiring or fuse, or defective speed sensor. Repair or replace as necessary.
