P132B is a code related to the calibration from the recall 06E17 (part of the Inferred EBP strategy). It means that there is a problem with the VGT system. P132B is a fault code that is set if the required boost levels are not achieved during a learn cycle or at specific speed fuel demand points.
This code indicates that there are issues with the turbocharger, MAF sensor, MAP sensor/hose, IAT2 sensor, intake leaks, or exhaust leaks, etc. Frequently it is a sticking turbo issue. This code can also throw a P0401 EGR code. (see video below at 1:55)
On vehicles built before Sept 29, 2003 (PCM ignores EBP sensor input and infers the value from the MAP and MAF sensors). On these vehicles, the MAF is used for fuel correction. The PCM will learn MAP and MAF and then learn the VGT action by cycling the VGT duty cycle in steps from 85% to 0%, and then back up, again in steps. It will learn the MAP and MAF action during this process. It takes 6 cycles to learn the VGT. P132b will be set if the PCM determines that there is something wrong with what it learned for MAP and MAF as it relates to VGT duty cycle.
edit - sorry the video link is no longer valid. I will try to see if I can find another link.
P132b is a tough nut to crack sometimes!
