The speed sensor on a 1998 Ford Mustang is a three-wire sensor located on the rear axle housing. The wires are:
* Pink/black wire: This wire is the signal wire from the speed sensor. It sends the speed signal to the electronic control module (ECM).
* Black/orange wire: This wire is the ground wire for the speed sensor.
* Green/red wire: This wire is the power wire for the speed sensor. It provides 12 volts of power to the speed sensor.
To test the speed sensor, you can use a multimeter to measure the voltage between the signal wire and the ground wire. The voltage should be between 0 and 5 volts. If the voltage is not within this range, the speed sensor is faulty and needs to be replaced.
You can also test the speed sensor by using a scan tool to read the trouble codes from the ECM. If there is a code related to the speed sensor, it will be displayed on the scan tool.
