OK.....here is what I found out.....it just confuses me more. Maybe it IS the EBP sensor??
So I went out to the shop and turned the key on and let my Torque App on my phone sync with the bluetooth ODBIII dongle so I could read all of the PID's.
With key on, engine off.....here is what I'm getting. MAP: .1, EBP 14.2, VGT 0.0, and I was showing a P0299 (turbo underboost) and P2262 (turbo boost not detected) faults.
I fired up the truck, it started right up......but instantly I noticed that I didn't have that typical turbo whistle coming from the exhaust....it just sounded rumbly, with no turbo whistle at all. I fiddled around around with the EGR and VGT plugs while it was idling....no change. Went around and moved all of the wiring around....no change.
With the engine cold and idling....this is what I got. MAP: -.1, EBP was at 40 but then dropped to around 15, VGT was up at 85% (which it always does since I don't have a muffler or cat).
So I let it warm up, and took it for a drive. Same as before. NO power, I could only get around 10psi MAP (boost), and the VGT was moving around between 40-60%. NO power, and just a hint of turbo wine. It wasn't blowing any white or black smoke...just no power. The one strange thing I noticed is that the gauge on the dash stayed about at 0-1, even with the MAP was at 10psi....strange.
So I get home.......and let it idle for a little bit. The VGT is around 67%, EBP is 16.5, and MAP is around 0-.1.
I turn the key off for a second or two, turn it right back on.....fires up, instant turbo whistle out of the exhaust, everything seems normal again. The other strange thing that happened is that as soon as I fired it up, all of my PID's on my Torque App said NO DATA...not sure why. I turned the truck off, and back on...then the PID data all came back. I cleared the PCM faults, and I go take it for a ride.....it's all back to normal!! Good boost, great power, the dash boost gauge is working now....perfect! That's the exact same thing it did the other day. Runs like crap, no boost, warm it up really good, turn it off, back on...and it's all back to normal.
I get back to the house.....no codes, everything is fine. I let it idle and EBP is now at 40, 1.0 MAP, 65 VGT, 22.8 IPR, 580 HPOP....everything perfect!!!!
So what the hell happens when I turn the key off for a second?? What's the EBP supposed to be at idle?? Why would it read 15 at idle, and then 40? This is driving me nuts!!
Could it have something to do with me getting it out and running it to heat up the exhaust...and that does something to the EBP sensor to make it start working as soon as I turn the key off and restart the truck?? It's definitely not a leak, it's something electrical.
