Fig. 61: Intake Air Temperature Graph The Intake Air Temperature (IAT) sensor, mounted on the Mass Air Flow (MAF) meter, monitors the IAT. The The IAT sensor is powered by a 5 V supply from the THA terminal of the ECM, via resistor R. Resistor R and the IAT sensor are connected in series. When the resistance value of the IAT sensor changes, HINT: When any of DTCs P0110, P0112 and P0113 are set, the ECM enters fail-safe mode. During fail-safe mode, the DTC TROUBLE DETECTION CONDITION CHART DTC No. DTC Detection Condition Trouble Area P0110 Open or short in IAT sensor circuit for 0.5 seconds (1 trip Open or short in IAT sensor IAT sensor (built into MAF ECM
