Nissan Rogue (T33) 2021-Present Service Manual: Turbocharger Boost Sensor

Component Inspection

CHECK TURBOCHARGER BOOST SENSOR

1. Turn ignition switch OFF.

2. Remove turbocharger boost sensor with its harness connector.

3. Install pressure pump (A) to turbocharger boost sensor (1).

   

   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 follows.

   ECM
   Connector	Terminal
   F71	81	107

   NOTE:

   Ｔhe sensor is absolute pressure sensor, output value may differ depending on atmospheric pressure and altitude.

6. Measure the atmospheric pressure.

   NOTE:

   As the atmospheric pressure described on the synoptic chart is the value at sea level, compensate the pressure with the following chart.

   Altitude (m)	Compensated pressure (hPa)
   0	0
   200	−24
   400	−47
   600	−70
   800	−92
   1000	−114
   1500	−168
   2000	−218

7. Check the absolute pressure sensor value corresponding to the atmospheric pressure.

   Atmospheric pressure (hPa)	Voltage (V)
   800	1.2 – 1.5
   850	1.3 – 1.5
   900	1.3 – 1.6
   950	1.4 – 1.6
   1000	1.4 – 1.7
   1050	1.5 – 1.8

8. Confirm the difference of the absolute pressure sensor voltage between at atmospheric pressure condition and at the following pressurized condition.

   NOTE:

   • Always calibrate the pressure pump gauge when using it.

   • Inspection should be done at room temperature [10 - 30°C (50 - 86°F)].

   Condition [Pressure (Relative to atmospheric pressure)]	Voltage difference (Approx.)
   40 kPa (−300 mmHg)	+ 0.5 V

Is the inspection result normal?
