FI SYSTEM DIAGNOSIS
Step 3 1) Turn the ignition switch OFF. 2) Check the continuity between Yellow wire and ground.
3
$ 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. (#7-2)
3
6) Disconnect the position sensor coupler and measure the resistance. (between Yellow and White wires)
3
$ Position sensor resistance at adjustment position: Approx. 3.1 kΩ (+ Yellow – - White) ! 09900-25008: Multi circuit tester set % Tester knob indication: Resistance (Ω) Is the resistance OK? YES NO
Go to Step 4. Replace the EXCVA with a new one.
