Vehicle Speed Sensor

NOTE: If speedometer operates, vehicle speed sensor is okay.

Connect AC voltmeter (5-volt scale) across vehicle speed sensor connector terminals. See Fig 1 . Turn drive wheels by hand (if necessary, remove vehicle speed sensor and turn shaft gear by hand). If voltage pulses are detected, vehicle speed sensor is okay. If voltage pulses are not detected, replace vehicle speed sensor.
