P132B Turbocharger boost control A peformance
I have a 2003 F350 6.0L with a DTC P132B code. It has had the 06E17 Feild service action peformed in 2006. I have just finished doing a HPOP, EGR Cooler, Oil cooler,Turbo Cleaning and vane check. It was impressively clean for 193000 miles in the turbo, but I cleaned it anyway. I looked for coking in the VGT Control Valve and found nothing significate. There was a small amount of build up at the cam and on the tip of the control valve. This truck has no boost when you start off and when it shifts into 2nd gear, it will begin to pull harder and have a slight whine from the turbo. I smoke tested the intake side and found a small leak at the output side of the CAC where the hose clamp was not tight enough. Tightened it and no leaks. Exhaust side was also smoke tested and had a leak at the Morman clamp on the exhaust intake side of the turbo. I have not sealed it up yet. Waiting on the clamp. I hooked the MAP hose up to a vacuum gauge to compare MGP to gauge and they both stayed at 0. The vacuum gauge needle was bouncing rapidly and when I disconnected the hose and put it up to my ear, I could hear a throaty sound with just a wisp of air coming from it. I put a new EGR valve in it and I am wondering if it is open just a little and causing no vacuum at the MAP. Any ideas?
