Absolute Pressure Sensor: Locations
TMap Sensor & MAP
On the MINI COOPER S the pressure differential is measured across the supercharger to determine the manifold air density.
To measure this differential two sensors are fitted, one on either side of the supercharger. The TMAP is fitted on the manifold pressure side and has the
same hardware specification as the MINI COOPER sensor but the maximum pressure range is 250 Kpa.
The MAP sensor is fitted upstream of the TMAP between the supercharger and the throttle body and measures the atmospheric pressure. This sensor is
the same as the MINI COOPER TMAP but will not have the temperature sensor.
The TMAP sensor is located in the intake manifold where it is exposed to higher than atmospheric pressures as produced by the supercharger. The MAP
sensor is located between the supercharger and the EDR, a location not effected by additional pressures from the supercharger.
