Mr. Sandman Posted November 16, 2014 Share Posted November 16, 2014 My wife's 07 Suburban (5.3 liter) keeps throwing code B2AAA per my Scan Gauge II. My friend Google says this is a non-existent mystery code. Any ideas on what to look for besides another code reader or a trip to the dealer?

SAND~~SNAKE Posted November 16, 2014 Share Posted November 16, 2014 That number does not exist in Gm database. You got the number wrong or you need the chuck that scanner in the round file. Quote Link to comment Share on other sites More sharing options...
aseman Posted November 26, 2014 Share Posted November 26, 2014 Sounds like a code reader glitch. Quote Link to comment Share on other sites More sharing options...
Mr. Sandman Posted November 27, 2014 Author Share Posted November 27, 2014 The Scan Gauge II code reader works great on my piece of sh!t Ford 6.0 and all of its codes but for some reason it picked up the Chevy code as a B2AAA. I borrowed a Snap On code reader from work and the real code is P0121, throttle position sensor. Now I just need to figure out what it'll take to correct it. Any ideas?

SAND~~SNAKE Posted November 27, 2014 Share Posted November 27, 2014 1st Load test your battery and make sure the cables are clean and tight. 2nd Clean the throttle body, clear the code and relearn idle position. It will probably idle high unless it is relearned after it is cleaned. If you can't relearn it take to someone who can. Idle air composition should reset from what ever number it's currently at to 0%. If 1 &2 do not correct your problem replace throttle body.

I realize this issue is several years old but the code B2aaa Pe has to do with an incompatibility on the part of your scanner. It did not have the ability to pick up certain dtc codes that were coming up. Quote Link to comment Share on other sites More sharing options...
