Help with 2 codes: 2ADF and 2ABD

joec500 · 06-18-2012, 10:41 PM

2ADF idle running control, speed

2ABD intake pressure sensor re-running.

I get these codes simultaneously and have not been able to get a clear answer through search. I checked the MAP sensor and it seems secure. My next step will to be search for a vacuum leak, but was curious if anyone else might have a starting place.

Thanks!

my rear turbo (bank2) inlet pipe was loose causing a vacuum leak. It cost me a fair bit in labor to discover this and tighten up the inlet pipe, but this hasn't been an issue since. Have you ever had your turbos replaced? Sometimes the techs do not install the inlets tight. There is a bracket that holds the inlet in place and sometimes it gets bent and doesn't do it's job with holding on the inlet pipe on the rear turbo.

Either way...you have a vacuum leak somewhere.
