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).
Pressure | Terminal No. | Standard |
−88 kPa (−0.9 kg/cm2, −12.8 psi) | 2 (+) and 1 (−) | Approx. 1 V (when 25°C (77°F)) |
