Codes 0402 and 132P
I have an '03 6.0 Excursion, stock. I do have a CTS Insight for monitoring purposes. I drove it yesterday (wife usually drives), and he seemed to stumble on occasion and I could hear the turbo flutter occasionally. Usually these happened around 1800-2000 rpm, part throttle, when steady or accelerating. Highway driving it was not noticeable. I looked at the CTS and found the two trouble codes (0402 and 132B).
After reading many posts on the subject, some say clean the EBP sensor and tube, but some say that on the '03, that the EBP is no longer read by the computer. I looked at the MAP sensor and hose and they were clean. While watching the gauges, when there was a stumble, the MAF reading would drop drastically, but very quickly and return to more normal (for what was shown) readings. Today I checked the VGT% and at idle it was 60-70+% and when I hit the accelerator, it would drop. I don't see or smell exhaust from the Y-pipe area. I do get EBP readings from the CTS. What can/should I look for on the CTS? and what figures? Lastly what else can I check myself? The EGR valve is not very old, it was replaced about 20K miles ago.
