Need some help with EBV sensor

I found diesel soot around the fuel filter and GPR, which puzzled me until I found a hole in the little tube running from the exhaust manifold to the EBV Sensor.

Since I don't have an EBV anymore, I'm tryin to decide what to do with the sensor. I know it controls the EBV in cold weather, but does it do anything else regarding performance?

Dennis at ITP suggested routing boost pressure to the EBV sensor so it has something to see, keeping the PCM happy. But it uses -05JIC fittings and I'm having a little trouble finding them locally.

Anyone have any experience with this? Will I piss off the PCM if I simply unplug the sensor and chuck it? By "piss off" I mean affect performance or set the SES light: I don't care if it sets a "look at the bad sensor" code.

So what do you guys think? Thanks in advance /ubbthreads/images/graemlins/biggrin.gif

My question for HnH (et all) is I just had my PSD hooked up to AE last weekend and at an idle or no boost the EBP was reading a steady 28.XX to 29.XX and the MAP sensor was reading 11.3 at the same time. I was told that these readings should be a whole lot closer to each other at an idle or zero boost? These sound like the two readings that HnH is using to measure "drive pressure", correct? When boosted (~15 psi) the MAP sensor and the EBP sensor both jumped about 15 psi to 27 and 44 respectively. Any thoughts? Is one of the two sensors reading incorrectly?

Not really a thread hijack but intended to just add to the OP's questions.

I had the same problem last week. I changed out the EBPS and now it reads 14.7 and 14.9 respectively at idle and KOEO with AE. I still get the P0475 code. /ubbthreads/images/graemlins/shrug.gif ***? How do I get rid of the codes if a new sensor won't fix it? The dongle thing is a no-go thing with me, never have any luck with SP devices. While driving My truck reads 28psi of boost and 32psi of back-pressure. Actual readings, not absolute pressures, Not bad.

Yes, I had one in the glove box just in case I had an issue down the road. It kept the CPS company. It seemed to fix my problem with high pressure readings and throwing codes for 50psi of backpressure.

Now that makes sence. I just looked it up on AE and it says Exhaust Pressure Control Valve, that must be from my DIY exhaust brake I use quite a bit. I should have picked up on that before. Thanks, I appreciate you pointing out what I over looked. Sometimes you focus and can't see the forrest for the trees.
