4-54 FI SYSTEM DIAGNOSIS
Step 1 (When indicating P0110-L:)
1) Turn the ignition switch 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.
4) Disconnect the IAT sensor coupler.
5) Check the continuity between Dg wire A and ground. If the
sound is not heard from the tester, the circuit condition is OK.
Tester knob indication: Continuity test ()
6) Connect the IAT sensor coupler and turn the ignition switch
ON.
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 set
09900-25009: Needle pointed probe set
Tester knob indication: Voltage ()
Are the continuity and voltage OK?
