· Engine speed higher than 1200 rpm
Throttle valve aperture greater
than 5 % Intake manifold absolute pressure less than 140 hPa
· Engine speed lower than 1200 rpm
Intake manifold absolute pressure
less than 140 hPa
If
trouble code 34 was recognized, the system calculates with the following
replacement functions:
Engine
not running:
Intake
manifold pressure equals 1000 hPa
Engine
running:
The
control unit calculates the intake manifold pressure depending on the engine
speed and throttle valve position.
