4-54 FI SYSTEM DIAGNOSIS
5) Measure the voltage between Dg wire terminal
ground.
6) If OK, then measure the voltage between Dg wire terminal
and B/Br wire terminal
IAT sensor input voltage: 4.5 – 5.5 V
\ 09900-25008: Multi-circuit tester set
W Tester knob indication: Voltage ()
Is the voltage OK?
YES Go to Step 2.
• Loose or poor contacts on the ECM coupler
NO (terminal
• Open or short circuit in the Dg wire or B/Br wire
Step 1 (When indicating P0110-H:)
1) Turn the ignition switch OFF.
2) Lift and support the fuel tank. ( 5-3)
3) Check the IAT sensor coupler
If OK, then check the IAT sensor lead wire continuity.
4) Disconnect the IAT sensor coupler and ECM coupler.
5) Check the continuity between Dg wire
6) Also, check the continuity between B/Br wire
.
IATS lead wire continuity: Continuity (?)
\ 09900-25008: Multi-circuit tester set
09900-25009: Needle pointed probe set
= Tester knob indication: Continuity test (?)
Is the continuity OK?
YES Go to Step 2.
NO Dg wire or B/Br wire open
7) After repairing the trouble, clear the DTC using SDS tool.
