Pressure sensor
Application
- MAP (Manifold Absolute Pressure) sensor;
- boost pressure sensor;
- atmospheric pressure sensor;
- fuel pressure sensor;
- fuel tank pressure sensor;
- oil pressure sensor.
Output voltage waveform from a properly functioning MAP sensor (Mitsubishi Lancer 1.6 2005). The output voltage of the sensor decreases with increasing vacuum in the intake manifold.
A – engine start;
B – running at idle;
C – snap throttle (acceleration);
D – deceleration;
E – running at idle;
F – engine shut off.
Snap throttle and deceleration
Engine running at idle.
Output voltage waveform from a properly functioning MAP sensor with frequency output. KOEO (Key On Engine Off). (FORD Scorpio 2.0i 1990).
Engine running at idle.
Output voltage waveform from a properly functioning boost pressure sensor during a snap throttle.
