Step 3
1) Turn the ignition switch OFF.
2) Check the continuity between Y wire and ground.
 Position sensor continuity: ∞ Ω (Infinity)
3) If OK, then measure the position sensor resistance.
4) Connect the position sensor coupler.
5) Set the EXCVA to adjustment position. (6-4)
6) Disconnect the position sensor coupler and measure the
resistance. (between Y and W wires)
 Position sensor resistance at adjustment position:
Approx. 3.1 kΩ (+ Y – - W)
 09900-25008: Multi circuit tester set
 Tester knob indication: Resistance (Ω)
Is the resistance OK?
YES Go to Step 4.
NO Replace the EXCVA with a new one.
