FI SYSTEM DIAGNOSIS 4-576) Disconnect the ECM coupler.7) Check the continuity between G/Y wire C and terminal P.8) If OK, then check the continuity between B/Br wire B and terminalS. APS lead wire continuity: Continuity () 09900-25008: Multi-circuit tester set09900-25009: Needle pointed probe set Tester knob indication: Continuity test ()Is the continuity OK?YES Go to Step 2.NO G/Y wire shorted to VCC, or B/Br wire open9) After repairing the trouble, clear the DTC using SDS tool.(4-26)1ECM couplers (Harness side)]Step 1 (When indicating P1450-L:)1) Turn the ignition switch to OFF.2) Remove the front seat. (8-3)3) Check the AP sensor coupler for loose or poor contacts.If OK, then check the AP sensor lead wire continuity.14) Disconnect the AP sensor coupler.5) Check the continuity between G/Y wire C and ground.6) Also, check the continuity between G/Y wire C and B/Br wireB. If the sound is not heard from the tester, the circuit conditionis OK.1V
