4-34 FI SYSTEM DIAGNOSIS
Step 2
1) Turn the ignition switch OFF.
2) Measure the IAT sensor resistance.
% IAT sensor resistance:
Approx. 2.45 kΩ at 20 °C (68 °F) (Terminal – Terminal)
! 09900-25008: Multi circuit tester set
& Tester knob indication: Resistance (Ω)
Is the resistance OK?
• Dg or B/Br wire open or shorted to ground, or
poor D or X connection.
• If wire and connection are OK, intermittent trou-
YES
ble or faulty ECM.
• Recheck each terminal and wire harness for
open circuit and poor connection.
NO Replace the IAT sensor with a new one.
Intake Air Temp
20 °C (68 °F)
40 °C (104 °F)
60 °C (140 °F)
80 °C (176 °F)
NOTE:
IAT sensor resistance measurement method is the same way as
that of the ECT sensor. Refer to page 6-10 for details.
