Had my FLAPS pull codes for me yesterday, and this is what I got...Boost sensor CKT A range performance. I read up on it in the Helm manual, but I'm still confused. What does this one mean to me, and how serious is it? The SES light came on Monday afternoon. The truck sat all day Tuesday. Drove it yesterday, and the light came on during the 50 mile ride home. What say you?

Thanks, all!

The turbo wastegate is actuated by vacuum from the vac pump. The plastic lines can get brittle and crack loosing vac to the wastegate.

There is a boost controler that controls the amount of vac and that can get sticky and not work properly. Start by tracing vac lines you'll figure it out.

Thanks. I'll check it out after work and advise.
