Vehicle Speed Sensor (Digital Instrument Cluster)

Faults in vehicle speed sensor circuit may set Code 14. To test system, see CODE 14 diagnostic procedures in TESTS W/CODES article.

To test sensor, remove vehicle speed sensor from trans-mission. While rotating sensor shaft by hand, check AC voltage across sensor connector terminals. If about .5 volt AC is not present, replace sensor.
