Specification data are reference values and are measured between each terminal and ground.

CAUTION: Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in damage to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

INPUT/OUTPUT VOLTAGE

TERMINAL NO.	WIRE COLOR	ITEM	CONDITION	DATA (DC Voltage)
49	L	Sensor power supply (Refrigerant pressure sensor)	[Ignition switch: ON]	Approximately 5V
