Why is throttle body butterfly valve plate stuck in closed?
It looks like DAL permanently removed the right side of the TB and made a jumper from the accelerator pedal opening sensor to the throttle valve opening sensor since they’re the same output (pgs 19-114 through 19-116). Last edited by Mac Attack; 11-27-2009 at 10:28 .
When to replace throttle body and throttle pre flap?
If there are leaks this in itself can result in the same symptoms that a defective throttle body/pre-flap would give. The last check is to inspect the part itself. If the inside walls appear to be oily or carbonised this will restrict airflow. If carbonised, the part will need to be replaced.
What to do if your butterfly valve is stuck?

I sprayed carb cleaner and some break cleaner into the throttle body to wash out the sanding residue. After doing this, the butterfly valve is stuck closed!

What causes the throttle body to get stuck?
Even if you have an air filter on your car, dirt and soot come from the turbocharger, EGR valve, and the crankcase ventilation and get stuck on the throttle body valve. After a whole, it will cover the valve so much that the RPM will be affected.
Why is the air inlet valve stuck open?
Air Inlet valve can be interpreted as the Throttle. It may either be the throttle electronic sensor (in the head of the throttle) has developed a fault and thus the throttle flap vane is not returning home, or as it was in my case the throttle gasket had failed on one edge and was allowing incorrect volume of air.
Where is the throttle body on a car?
The air will travel up the intake and it will reach your throttle body. The throttle body is a circular valve that’s located in between your air filter and Intake Manifold. In the old days, there was a wire attached to the gas pedal of your car and it would move accordingly to how you pressed it.
