What Does The Map Sensor Do
This part is commonly referred to as the map sensor. A failed map sensor has serious implications on fuel control vehicle tailpipe emissions and fuel economy.

However not all faults will call for a sensor replacement.
What does the map sensor do. The manifold absolute pressure sensor provides instantaneous manifold pressure information to the engines electronic control unit ecu. This is because the map sensor measures absolute pressure based on a perfect vacuum rather than atmospheric pressure. To check for a faulty map sensor a complete engine diagnostic will need to be performed.
The purpose of the map sensor is to measure the pressure within the intake manifold relative to the ambient barometric pressure. Ignoring a faulty map sensor can lead to other engine problems so it still should be checked if a problem is suspected. Symptoms of a bad or failing map sensor include.
The manifold absolute pressure sensor map sensor is one of the sensors used in an internal combustion engines electronic control system. In modern vehicles a computer and a series of sensors control the engines fuel consumption and other operations. Replacing a map sensor requires some technical skill.
Here we will describe and discuss the manifold absolute pressure sensor of the engine. The manifold absolute pressure or map sensor is a common component on modern vehicles. At 20 hg the map sensor will indicate about 5 psi.
Engines that use a map sensor are typically fuel injected. While you may never have to work on any of these sensors yourself one in particular is essential to a smoothly running engine the map manifold absolute pressure sensorwhat is a map sensor and what does it do. This information is sent to the engine computer which adjusts other variables such as the rate of.
So the article below will explain about the map sensor function working principle and the symptoms you can look out for if it were to go bad.
