Intake Air Temperature
P0111 Intake Air Temperature Sensor 1 Circuit Range/Performance
P0112 Intake Air Temperature Sensor 1 Circuit Low
P0113 Intake Air Temperature Sensor 1 Circuit High
Description
The combined sensor which measures both Mass Air Flow (MAF) and Intake Air Temperature (IAT) is incorpo-
rated into the air box. The IAT sensor is a thermistor device which changes resistance with temperature. As
air intake temperature decreases the thermistor resistance value increases, and conversely as air temperature
increases so the thermistor resistance value decreases.
