Sensor Inspection
- Using a multimeter, measure the IAT sensor resistance between terminals 3 and 4.IAT SENSOR RESISTANCE SPECIFICATIONS
IG. SW. ON Temperature °C (°F) Resistance (kΩ) 0 (32) 4.5~7.5 20 (68) 2.0~3.0 40 (104) 0.7~1.6 80 (176) 0.2~0.4 - If the resistance deviates from the standard value, replace the intake air temperature sensor assembly.
