So I installed a manual boost controller and as soon as I started the car the SES light came on....does putting a mbc on cause that to happen because the car is not regulating the boost anymore?

 

No, go to autozone and find out what the code is.

 

Will they have the scan tool for my car, thats what i was going to do but wasnt sure if they would have the tool

 

I am going to guess you unplugged your factory BCS.

The vacuum lines dont need to be attached but the solenoid needs to stay plugged in.

 

Ill have to check that too and see if thats what happened.

 

+1 All to often people take the factory BCS out and as stated above unless you are running a stand alone it has to stay plugged in, although it can be moved somewhere else. Also, I had a buddy put a MBC in and forgot to plug the MAF back in when he was done! LOL SES came on immediately also. Just a few things to look for. As for AutoZone or Advanced having the correct OBD II code reader, yes unless they are complete idiots they will be able to read your codes. The guys in my area where complete idiots so I just bought my own Scan tool.

Turns out its the IAT sensor, can anyone specify where this sensor is located?

 

anyone?

 

under your intake box. It got two hoses coming out of it.

 

It is built in to your MAF sensor. Its odd that this code would come up and not a MAF code. If you damaged a wire in the harness that goes to the MAF, its possible.

Did you check to see if you left your factory boost control solenoid unplugged? Its possible that the code reader that was used was spitting out generic codes..

 

I thought he said the boost sensor, my bad.

 

I went and looked one of the pins got bent when i put my maf plug back in, bent it back and that got rid of the code. Thanks for the help ivan!!
