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


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.


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.


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

Terminal No.


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.


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.


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


Terminal No.


−88 kPa (−0.9 kg/cm2, −12.8 psi)

2 (+) and 1 (−)

Approx. 1 V (when 25°C (77°F))
