Ok so today I reset the ECU and everything was fine until about 3 hours after the reset and then it stumbled and threw a CEL. So after taking a drive to my local Autozone for the use of there Tech II to pull the code and came up with a P1110 IAT Air/Fuel Temp sensor failed loop So reset the codes and so far it has not come back. This is the first time I have seen this error on my car and was curiousif anyone else has had this error on their car?

I found the answer on SC I think being as there are 3 people who got the same code and it was the same part for each one. I used the Autozone TechII and it points to IAT being hte issue but that is not entirely true as the issue pops up due to an increase in Intake temps caused by a bad Boost Pressure Control Valve (BPC). It basically seems to get stuck in 1 of 2 positions and those are either "closed shut" thus elimating boost or "wide open" thus causing overboost and high engine temps due to excessive boost pressure with a closed TB. I ordered a new part from The Saabsite for $44 and it got here today so I will see for sure if this corrects it when I get home and install it.

If it does them I am going to write this one up as a troubleshooting FAQ to be posted for the records! :D

On a side note when I called the dealer to ask about the part the counter guy answers "Hi this is (insert Name), Saab parts Specialist" so I asked for the part and gave him the SAAB part number to which he responded "What kind of car is this for?" . At this point I repeated 2000 9-3 SE HOT 205R to which I got "205R? is that some Euro thing or what is that number for?". Now at this point I told him to never mind I would call the other Orange County SAAB dealer and deal with them. The final response from him was "I would be glad to help you but are you sure you are talking about a SAAB car? " at which point I hung up......................So hard to find good help these days!!!! :x

Are you talking about the Bypass or Diverter (Europe term) Valve off of the delivery pipe...when you say BPV?

The valve I'm thinking your talking about recircs boost not used into the turbo inlet, between shifts or when you let off the gas. The one connected to the delivery pipe, and the intake pipe into the turbo.

It might be that you used the wrong name to describe it..because there's another valve called the Boost Controller where three hoses run out and located normally near the radiator.

I just wasn't sure when you said "Boost Pressure Valve" what you meant either.

No the BPC (Boost Pressure Control Valve) is what replaced the APC it is located on the passenger side front of the car and has 3 hose connections going to it. It controls your boost pressure while you are driving (the device that will force you into limp home mode!!).

I will attach a picture for it later today.
