TMAP Sensor (MINI COOPER)

The TMAP (Temperature and Manifold Absolute Pressure) sensor contains a Manifold Absolute Pressure (MAP) Sensor and an Intake Air Temperature Sensor.

The Manifold Absolute Pressure Sensor is a Piezo-resistive pressure gauge that supplies an analog input to the EMS2000 corresponding to the absolute manifold pressure. The signal is used to determine the engine load. The engine load information is used for internal engine control via the EMS2000 (such as to control fuel delivery and ignition timing) and for traction control regulation.

The Manifold Absolute Pressure (MAP) sensor measures the changes in the intake manifold pressure which result from engine load (intake manifold vacuum) and RPM changes; and converts these into a voltage output. By monitoring the sensor output voltage, the EMS2000 knows the manifold pressure.

• At idle manifold pressure is lower (high vacuum) and output voltage will be about 1 to 2 volts.
• While at higher pressure or at Wide Open Throttle (lower vacuum) output voltage will be about 4 volts.
