Best Answer: The oil pressure sensor is actually an electronic transducer which allows more electricity to flow in direct proportion to the pressure applied to a pressure sensitive medium. That electrical signal is translated to a pressure reading on the gauge on the dash of your car. It is mounted on the outside of the engine block and connected by a drilled passage to the pressurize oil gallery ( a fancy name for the main oil passage ) so that the sensor reads the pressure in the gallery directly. If a sensor leaks it will cause oil to drip on the ground but this is a very rare thing.
The Manifold Absolute Pressure (MAP) sensor is used by the Powertrain Control Module (PCM) for engine load input. The PCM uses this input, as well as others, to calculate the correct amount of fuel to inject into the cylinders. The MAP sensor measures the absolute pressure inside the intake manifold of the engine. At sea level, atmospheric pressure is about 14.7 psi (pounds per square inch). When the engine is off, the absolute pressure inside the intake equals atmospheric pressure, so the MAP will indicate about 14.7 psi. At a perfect vacuum, the MAP sensor will read 0 psi. When the engine is running, the downward motion of the pistons create a vacuum inside the intake manifold (For the purposes of engine control, when a technician says vacuum, what they are really saying is pressure that is less than atmospheric pressure).
