   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°C (50 - 86°F)].

   ECM			Condition [Pressure (Relative to atmospheric pressure)]	Voltage(Approx.)
   Connector	+	-
   	Terminal
   F51	47	45	0 kPa(0 mbar, 0 mmHg, 0 inHg)	2.03 V
   			40 kPa(400 mbar, 300 mmHg, 11.81 inHg)	2.67 V
