General Description

Vehicle Speed Sensor(VSS) is hall sensor type and senses the rotating speed of differential gear mounted on transaxle. Comparing engine speed with vehicle speed calculated based on vehicle speed sensor signal, ECM recognizes engaged gear. And based on the information about engaged gear, ECM performs optimum fuel injection quantity correction. VSS signal is also used in speed meter of cluster, ETACS(or BCM), aircon control module, navigation system, etc.

DTC Description

P0501 is set when vehicle speed below 15Km/h is detected for more than 1 sec. at above 3500RPM and above 38.25 mg/hub of fuel injection quantity.
