I would put a pipe plug in the exhaust manifold and you could either put the dongle SP diesel sells on the end or leave it connected to the inoperative sensor. My EBPV is gone and that sets an P0475 error code (something about the solenoid for the EBPV) but my tube and sensor are intact so I have mine hooked up and it reports the manifold pressure to AE and the PCM etc. I Use this as a poor man's drive pressure indicator (Manifold pressure -1 atm = drive pressure. I do not think the PCM will defuel with in the absence of the EBPV. Wonder how high the manifold pressure gets with the EBPV closes? Highest drive pressure I have seen with the H2e is 38 psi with boost of 33 psi.
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

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 ***?
[/ QUOTE ]I called Sean (SP Diesel) about this very issue as I had the dongle installed and still got this code. Well it turns out that the P0475 code indicates EBPV (not the sensor) non-function ie., Open/grounded circuit, solenoid open/shorted, failed PCM. So I think the PCM is looking for a response from the EBPV solenoid and is not seeing the solenoid so it is triggering this code. Sean pointed this out to me and suggested they could make a dongle for that circuit as well. /ubbthreads/images/graemlins/rolleyes.gif /ubbthreads/images/graemlins/rolleyes.gif
