Function Explanation (DTC Detection Outline)
- When there is an internal malfunction in IAT sensor No. 1, the MAF sensor/IAT sensor No. 1 sends a malfunction signal to the PCM. When the PCM receives a malfunction signal from the MAF sensor/IAT sensor No. 1, the MAF sensor/IAT sensor No. 1 determines an internal malfunction and stores a DTC. In addition, when the PCM receives a value other than the present standard for the output value from IAT sensor No. 1 continuously, the PCM determines that there is an internal malfunction in the MAF sensor/IAT sensor No. 1 and stores a DTC.
