Vehicle Speed Sensor: Testing and Inspection

VEHICLE SPEEDOMETER SENSOR
Speedometer / Inspection
1. Remove the combination meter. Refer to "Instrument Panel, Gauges and Warning Indicators".
2. Disconnect the speedometer connector (white).
3. Set the voltmeter to the 5V range.
4. Turn the ignition switch to LOCK position.





5. Measure the voltage between terminals "1L" and "1M" of the speedometer connector (harness side) with the rear wheels turning slowly.
6. If the voltmeter pointer moves slightly, replace the speedometer.

NOTE: If the pointer does not move, check the Vehicle Speedometer Sensor and/or wiring.

7. Connect the speedometer connector (white).
8. Install the Combination Meter.


Vehicle Speedometer Sensor / Inspection
1. Disconnect the negative battery cable.





2. Remove the Vehicle Speedometer Sensor.
3. Verify that magnetic resistance is felt when turning the vehicle speedometer sensor driven gear by hand.
4. Remove the front exhaust pipe (left side).
5. Disconnect the vehicle speedometer sensor connector.
6. Set the voltmeter to the 5V range.





7. Measure the voltage between terminals A and B with the rear wheels turning slowly.
8. If the pointer does not move, check the Vehicle Speedometer Sensor continuity.
9. Measure the resistance between terminals A and B.

Resistance: Approx. 290 ohms (at 20°C, 68°F)

10. If not correct, replace the Vehicle Speedometer Sensor.
11. Apply Automatic Transmission Fluid (ATF) to a new 0-ring and install it on the Vehicle Speedometer Sensor.





12. Install the Vehicle Speedometer Sensor.

Tightening Torque: 5.0-6.8 Nm (44-60 in.lb.)

13. Connect the Vehicle Speedometer Sensor connector.
14. Install the front exhaust pipe.
15. Connect the negative battery cable.
