Vehicle Speed Sensor (VSS)

Remove VSS from rear of transmission. See VEHICLE SPEED SENSOR under SENSORS & SWITCHES in REMOVAL & INSTALLATION article. Using an ohmmeter, measure resistance between VSS connector terminals. Resistance should be 560-680 ohms. Using a voltmeter set to AC voltage, measure voltage between VSS connector terminals. Place a magnet close to front of VSS and quickly remove (to generate a voltage pulse). If voltage pulse is not generated, replace VSS.
