Q: Under what conditions will the Throttle Body will go into Limp Home Mode on 2003 Saab 9-3

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
I have a 2003 Saab convertible with the 2.0 Turbocharged Engine. The Throttle Body has been going into Limp Home Mode on a fairly regular basis. I disconnect the battery terminal for about 30 minutes and reset the TB to it's non Limp Home Mode but it returns to Limp Home mode quickly. Could something other than a faulty TB be causing this?

there are several reasons,the most common are when the throttle position sensor goes bad,the sensor has double redundancy.and when they conflict your pcm will go into limp mode.another reason would be if the throttle body were physically sticking.also wiring could be an issue.these are issues with the TB only,there may be other concerns,you will have to have it scanned and diagnosed.
But in all likleyhood, it is the TB itself or a component of it that is causing the limp home condition
