OPERATION

See Figure 1


0900c152802600d5.jpg enlarge_icon.gifenlarge_tooltip.gif

Fig. Fig. 1: VSS with connector and driven gear
The Vehicle Speed Sensor (VSS) is a magnetic pick-up sensor that sends a signal to the Powertrain Control Module (PCM) and the speedometer. The sensor measures the rotation of the output shaft on the transaxle and sends an AC voltage signal to the PCM which determines the corresponding vehicle speed.


TESTING

  1. Disconnect the negative battery cable.
  2. Disengage the wiring harness connector from the VSS.
  3. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190-250 ohms, the sensor is okay.


REMOVAL & INSTALLATION

  1. Disconnect the negative battery cable.
  2. Raise and support the vehicle.
  3. Remove the catalytic converter Y-pipe.
  4. Unplug the VSS electrical connector.
  5. Remove the VSS protective heat shield.
  6. Remove the retaining bolt from the VSS.
  7. Lift the VSS out of the transaxle.
  8. Remove the driven gear retainer and the drive gear.

To install:
  1. Inspect the O-ring on the sensor and replace if necessary.
  2. Install the driven gear and the retainer.
  3. Place the VSS into the transaxle.
  4. Tighten the retaining bolt to 36-53 inch lbs. (4-6 Nm).
  5. Install the VSS protective heat shield.
  6. Attach the VSS electrical connector.
  7. Install the catalytic converter Y-pipe.
  8. Lower the vehicle.
  9. Connect the negative battery cable.
  10. ehichle speed sensor.

1994 GRAND MARQUIS Odometer stopped working, tridometer aswell


If the odometer and tripmeter stop incrementing their mile values, then the VSS or vehicle speed sensor is bad or has become disconnected.

Vehicle Speed Sensor OPERATION The Vehicle Speed Sensor (VSS) is a magnetic pick-up sensor that sends a signal to the Powertrain Control Module (PCM) and the speedometer. The sensor measures the rotation of the transmission output shaft or the ring gear on the differential and sends an AC voltage signal to the PCM which determines the corresponding vehicle speed.
TESTING
  1. Disconnect the negative battery cable.
  2. Disengage the wiring harness connector from the VSS.
  3. Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (ohmmeter function) between the sensor terminals. If the resistance is 190-250 ohms, the sensor is okay.
