Technology
Intake manifold pressure and intake air
temperature sender
The intake manifold pressure and intake air
temperature sender is located in the intake
manifold. From the signal, the engine control unit
recognizes the pressure and temperature of the
intake air. The signal is required for limiting
smoke in the dynamic range and to monitor the
function of the turbocharger (TDI only).
Functional description
The piezoelectric crystals in the intake manifold
pressure sender are changed by the pressure of
the air drawn in and thus send a voltage signal
to the engine control unit.
Substitute function
None
Effect
In the event of failure, there are no malfunctions
in engine operation
Engine electronic systems
