4-58 FI SYSTEM DIAGNOSIS7) Disconnect the ECM coupler.8) Check the continuity between R wire A and terminal A.9) If OK, then check the continuity between G/Y wire C and terminalP. APS lead wire continuity: Continuity () 09900-25008: Multi-circuit tester set09900-25009: Needle pointed probe set1] Tester knob indication: Continuity test ()ECM couplers (Harness side)Is the continuity OK?YES Go to Step 1 (4-56) and go to Step 2.NORed or G/Y wire open, or G/Y wire shorted toground10) After repairing the trouble, clear the DTC using SDS tool.(4-26)Step 21) Connect the AP sensor coupler and ECM coupler.2) Insert the needle pointed probes to the lead wire coupler.Turn the ignition switch ON.3) Measure the AP sensor output voltage at the wire side coupler(between G/Y and B/Br wires). AP sensor output voltage: Approx. 3.6 V at100 kPa (760 mmHg)(+ G/Y – - B/Br) 09900-25008: Multi-circuit tester set09900-25009: Needle pointed probe set Tester knob indication: Voltage ()YES Go to Step 3.NO• Check the air passage for clogging.• Open or short circuit in the G/Y wire• Replace the AP sensor with a new one.4) After repairing the trouble, clear the DTC using SDS tool.(4-26)2V
