FI SYSTEM DIAGNOSIS 12-47
Step 2
1) Connect the ECM coupler.
2) Disconnect the IAT sensor coupler.
3) Measure the IAT sensor resistance.
IAT sensor resistance: Approx. 2.58 k
Ω
at 20 °C (68 °F)
(Terminal – Terminal)
09900-25008: Multi circuit tester set
Tester knob indication: Resistance (
Ω
)
Is the resistance OK?
IAT sensor specification
NOTE:
IAT sensor resistance measurement method is the same way as
that of the ECT sensor. (

YES
• Dg or B/Br wire open or shorted to ground, or
poor

connection.
• If wire and connection are OK, intermittent trou-
ble or faulty ECM.
• 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.
