Manifold Absolute Pressure and Temperature Sensor (TMAP)

Manifold Absolute Pressure And Temperature Sensor (TMAP)





The MAPT (manifold absolute pressure and temperature) is located to the rear of the RH (right-hand) engine bank intercooler outlet. The sensor measures the pressure and temperature of the inducted air prior to it entering the cylinders.

The sensor fits and seals using a radial O ring seal directly to the inlet manifold.

The MAPT (manifold absolute pressure and temperature) signal is used to retard the ignition timing relative to boost pressure. The intercooler temperature is used for air charge density calculations and for intercooler diagnostic purposes.
