ENGINE CONTROL SYSTEM
IAT (Intake Air Temperature) SENSOR The IAT sensor is installed on the bottom of the ring gear cover and air intake silencer case and used to detect the intake air temperatureThis sensor is the same type as the cylinder temperature sensor, and inputs signal to the ECM as voltage valueThis signal is used to compensate the fuel injection time duration

MAP (Manifold Absolute Pressure) SENSOR The MAP sensor is installed on the collector assembly (top side) and used to detect the intake manifold (surge tank) pressureIt also detects the barometric pressure before starting the engineThis sensor inputs the intake manifold (surge tank) pressure to the ECM as voltage valueThis input signal is used as the fundamental signal to determine fuel injection time duration, ignition timing, etc
