Sensor Test

NOTE:
This test is only necessary if a PO5OO fault is flagged. An intermittent sensor will not be detected by this test.

NOTE:
Check ETM section E1 for circuit wiring.





1. Back probe cavity 27 (YK) of the red 36-way connector C1017 with the red tester lead (Figure 1).

2. Set PAC tester to a 200 ms time base and 0-16 volts range using the scope Icon.

3. Make sure the tester ground lead is properly connected.

NOTE:
Do not use Vehicle Speed Sensor preselect.

4. Switch ignition to position 2.

5. Observe the scope pattern while pushing the vehicle forward a few feet.





6. The sensor should switch between battery voltage and 0 volts (Figure 2).
