   CAUTION: When insert a pressure pump hose to the sensor, be careful to the damage of the sensor housing.
4. Turn ignition switch ON.
5. Check the voltage between ECM harness connector terminals as per the following conditions.
   NOTE:

   • Always calibrate the pressure pump gauge when using it.
   • Inspection should be done at room temperature [10 - 30 Deg. C (50 - 86 Deg. F)].

   Sensor	ECM			Condition [Pressure (Relative to atmospheric pressure)]	Voltage (Approx.)
   	Connector	+	-
   		Terminal
   Turbocharger boost sensor (bank 1)	F142	116	99	0 kPa (0 mbar, 0 mmHg, 0 inHg)	2.03 V
   				40 kPa (400 mbar, 300 mmHg, 11.81 inHg)	2.67 V
   Turbocharger boost sensor (bank 2)		119	125	0 kPa (0 mbar, 0 mmHg, 0 inHg)	2.03 V
   				40 kPa (400 mbar, 300 mmHg, 11.81 inHg)	2.67 V

Is the inspection result normal?

YES
