4-56 FI SYSTEM DIAGNOSIS
Step 2
1) Turn the ignition switch OFF.
2) Measure the IAT sensor resistance.
IAT sensor resistance: Approx. 2.58 kΩ at 20 °C (68 °F)
\ 09900-25008: Multi-circuit tester set
V Tester knob indication: Resistance (Ω)
Is the resistance OK?
• Dg or B/Br wire open or shorted to ground, or
poor
• 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.
