FI SYSTEM DIAGNOSIS 4-53Step 1 (When indicating P0110-L:)1) Turn the ignition switch to OFF.2) Lift and support the fuel tank. (5-3)3) Check the IAT sensor coupler for loose or poor contacts.If OK, then check the IAT sensor lead wire continuity.14) Disconnect the IAT sensor coupler.5) Check the continuity between Dg wire A and ground. If thesound is not heard from the tester, the circuit condition is OK. Tester knob indication: Continuity test ()1]6) Connect the IAT sensor coupler and turn the ignition switchON.7) Measure the voltage between Dg wire A and ground. IAT sensor output voltage: 0.15 – 4.85 V(+ Dg – - Ground) 09900-25008: Multi-circuit tester set09900-25009: Needle pointed probe set Tester knob indication: Voltage ()1VAre the continuity and voltage OK?YES Go to Step 2.NO• Dg wire shorted to ground• If wire is OK, go to Step 2.8) After repairing the trouble, clear the DTC using SDS tool.(4-26)
