FU(STI)-44 Manifold Absolute Pressure Sensor FUEL INJECTION (FUEL SYSTEMS) 4) Connect the Mighty Vac to the pressure port (A) of manifold absolute pressure sensor. 5) Check the voltage when generating vacuum and positive pressure using Mighty Vac. Do not apply vacuum of less than –88 — 200 kPa (–0.9 — 2.04 kgf/cm 2 , –12.8 — 29.0 psi). Do- ing so may damage the manifold absolute pres- sure sensor. When vacuum occurs at the pressure port of man- ifold absolute pressure sensor, the voltage will drop from the value as in step 3). When positive pres- sure occurs, on the other hand, the voltage will rise. Pressure Terminal No. Standard –88 kPa (–0.9 kgf/cm 2 , –12.8 psi) 1 (+) and 2 (–) Approx. 0.8 V (when 25°C (77°F)) 181 kPa (1.85 kgf/cm 2 , 26.2 psi) Approx. 4.7 V (when 25°C (77°F)) FU-04492 (A) |
