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 14-61 for details.
3) After repairing the trouble, clear the DTC using SDS tool.
