10. Throttle control
WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The requested air mass/combustion is converted to requested voltage for throttle position sensor 1. The charge air pressure and intake air temperature are used to correct this conversion. The throttle motor rotates the throttle until the current voltage for throttle position sensor 1 corresponds with the requested voltage.
NOTE:
The system regulates the current air mass/combustion so that it corresponds with the requested value. It is completely normal for the throttle not to be fully open despite the accelerator pedal being fully depressed.
