VEHICLE SPEED SENSOR (VSS)
VSS OPERATION OVERVIEW
The vehicle speed sensor (VSS)
q
is located on the RH
side of the transmission, accessed through the rear RH
wheel well.
The VSS is a Hall effect sensor. It operates on a three
wire circuit: 5 volt supply voltage, ground, and signal
back to the ECU. The Hall sensor is effectively a switch,
it closes when a tooth of the transmission output gear
passes within its operating range, and opens again when
the tooth moves out of range. The speed that the switch
opens and closes provides input to the ECU. The ECU
then interprets this switching into the speed the output
gear is rotating.
VSS TEST
1. Disconnect the three wire harness from the speed
sensor and remove the sensor from the transmission.
2. Connect the wires from the Static Timing Light
Harness (PN
2871745
) to the sensor 3 pin connector
using the Hall Sensor Probe Harness (PN
2460761
).
3. Pass a screwdriver back and forth in front of the
sensor tip.
4. Be sure connections are good and 9V battery is in
good condition. If the light flashes, the sensor is good.
VSS REPLACEMENT
1. Disconnect the three wire harness from the speed
sensor.
2. Remove the sensor from the transmission.
3. Install new speed sensor. Torque sensor to
specification.
TORQUE
