Subaru Crosstrek Service Manual: Inspection

FUEL INJECTION (FUEL SYSTEMS)(H4DO) > Manifold Absolute Pressure Sensor

INSPECTION

1. Check that the manifold absolute pressure sensor has no deformation, cracks or other damages.

2. Connect dry-cell battery positive terminal to terminal No. 3 and dry-cell battery ground terminal to terminal No. 1, circuit tester positive terminal to terminal No. 2 and the circuit tester ground terminal to terminal No. 1.

NOTE:

Use new dry-cell batteries.

Using a circuit tester, check that the initial voltage of each dry-cell battery is 1.6 V or more. And also check that the voltage of three batteries in series is between 4.8 V and 5.2 V.

For power supply, 5 V DC constant voltage power source can also be used.

3. Check the voltage at a normal atmospheric pressure.

NOTE:

The atmospheric pressure at higher altitude is lower than normal. Therefore, the voltage is lower than the standard value.

Terminal No.

Standard

2 (+) and 1 (−)

Approx. 4.2 V (when 25°C (77°F))

4. Connect the Mighty Vac to the pressure port (A) of manifold absolute pressure sensor.

5. Check the voltage when generating vacuum using Mighty Vac.

CAUTION:

Do not apply vacuum of less than −88 kPa (−0.9 kg/cm2, −12.8 psi). Doing so may damage the manifold absolute pressure sensor.

NOTE:

When vacuum occurs at the pressure port of manifold absolute pressure sensor, the voltage will drop from the value as in step 3).
