Trionic T7 is the newest of Saab's fuel systems. If
you have a Saab 9-5 , 2000 & up 9-3 or a 1999 Viggen this is
the system you will be running. The T7 system uses an electronic
throttle. If the system detects a throttle related fault it goes
into what is called limp home. Once you repair the fault you must
clear the code and manualy reset the throttle.
Remove Upper Engine plastic cover. Remove protective metal shield
that covers throttle body (2 bolts, 10mm heads)
Turn ignition on and clear all trouble codes. ( This step must be
done or system will just go back into limp home)
Turn off ignition and wait 12 seconds.
Under the throttle lever you will see the end of the spring. (looks
like an extra piece of wire sticking out from underneath where the
spring is wound) Push the end of the spring towards the throttle
With a small screw driver rotate the black toothed plastic disc
towards the back of the car. You will hear a click when correctly
done. (see image below)
Rotate the arm that is connected to the throttle cable (pedal arm)
towards the front of the car, and watch that the that the other
arm (throttle housing arm) does not rotate with the pedal arm.
If the arms move together you need to try again until this is accomplished.
Replace protective metal shield and plastic cover.
