DTC P0501 VEHICLE SPEED SENSOR A RANGE/PERFORMANCE

COMPONENT LOCATION

EF2D198E

VSS

SCMFL6505L

GENERAL DESCRIPTION

E6CA14C8

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

E93D55D0

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

1.

Connect Scantool to Data Link Connector (DLC).

2.

Warm engine up to normal operating temperature.

3.

Turn "OFF" electrical devices and A/C.

4.

Monitor "VEHICLE SPEED SENSOR " parameter on the Scantool.

specification : current vehicle speed is displayed.

Fig.1

Fig.1) Check if current vehicle speed is same as vehicle speed displayed on the Scantool.
