Features and benefits Feature and benefits
TMAP can provide two signals
The TMAP sensor provides 2 outputs
Intake absolute pressure signal derived from the pressure sensing element and processed by the chip
Intake manifold absolute pressure output /Derived from aMEMs based sensing element
Intake air temperature signal derived from thermistor
Intake manifold air temperature output / Provided by a NTCthermistor Together with information of cylinder volume,we can calculate the air mass.
Appearance and customer interface compatible with Bosch products

Product function Application
According to the TMAP output signal and cylinder/manifold volume,the ECU can obtain the intake air quality. In conjunction with the fuel pressure signal,the ECU can obtain the air-fuel ratio,thereby ob the optimal air-fuel ratio by adjusting the injection time.
With information of fuel pressure sensor,ECU can calculate the ratio of air & fuel,increase or reduce fuel injecting time to get the optimal ratio of air & fuel.
