MAP Sensors

Manifold Absolute Pressure sensors (MAP) are found in fuel injected engines. Mounted on the inlet manifold, they provide instantaneous manifold pressure data that the ECU uses to calculate air density and so determine the engines air mass flow rate. This information is crucial in order to meter the correct amount of fuel for optimal combustion.

Whilst the external appearance of a MAP sensor may match that of the unit it is replacing, it could be part of a "family" of sensors and so it is vitally important that it's calibration is correct. VM's may employ different calibrations for the different markets in which their vehicles are sold to take into account the average ambient temperature in that region. 

The Autotec range of Manifold Absolute Pressure Sensors recognise this and so ensure each unit supplied is correctly calibrated in line with the O.E. specification.
