Step 2
1) Turn the ignition switch OFF.
2) Measure the IAT sensor resistance.
! IAT sensor resistance:
Approx. 2.6 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 2 or D connection.
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
YES
• Recheck each terminal and wire harness for
open circuit and poor connection.
• Replace the ECM with a known good one, and
inspect it again.
NO Replace the IAT sensor with a new one.
Intake Air Temp
20 °C (68 °F)
50 °C (122 °F)
80 °C (176 °F)
110 °C (230 °F)
NOTE:
IAT sensor resistance measurement method is the same way as
that of the ECT sensor. Refer to Page 60 for details.
3) After repairing the trouble, clear the DTC using SDS tool.
