	Mass air flow sensor (with intake air temperature sensor)	MASS AIR FLOW SENSOR (WITH INTAKE AIR TEMPERATURE SENSOR)
	Electric throttle control actuator (with built in throttle position sensor and throttle control motor)	ELECTRIC THROTTLE CONTROL ACTUATOR
	EVAP canister purge volume control solenoid valve	EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE
	Intake manifold runner control valve actuator	INTAKE MANIFOLD RUNNER CONTROL VALVE
	Refrigerant pressure sensor	REFRIGERANT PRESSURE SENSOR
	EVAP service port	When perform the EVAP leak check, positive pressure is delivered to the EVAP system through the EVAP service port. Refer to INSPECTION .
	Transmission range switch	The transmission range switch is installed to upper part of transaxle case. ECM detects the selector lever position because the continuity of the transmission range switch line (the ON) exists.
