Resistance Values for an EBPS?
Backstory: Bought a new OEM EBPS back this summer and installed.
Recently, (last few months) MPG has dropped to around 13.
Coincidentally, I think it may line up with a spray down I did on the motor.
Last night, pulled EBP and voltage on AE and got 40 psi something and over 4V on the sensor KOEO.
Pulled the connector and found corrosion on the pins and in the connector. Tried to ring out the sensor, but don't know what the expected values are. Anyone have an idea of sensor values at sea level? I am trying to determine whether or not to pull the sensor and clean the sensor pins or just buy a new one and clean the connector and add grease to the pins.
On a side note, I do not understand why that connector would be corroded unless water penetrated through the wire connections or the sensor socket is cracked (couldn't see it in the dark). The rubber seal around the plug on the connection looks fairly water resistant so I doubt it would be the culprit. Any other ideas on the cause?

Found this for the sensor: ECSD - Exhaust Back Pressure (EBP) Sensor - 1994-1997 Power Stroke FAQ
With this in mind, I will clean the connector and sensor very well and look for difference in the AE. It is possible I have a ground in the connector with all of the corrosion and reference voltage is jumping. We will see after the cleaning. But it will have to wait until the monsoon subsides later this week.

I'm going to pull my oem replacement in the morning. I'll report findings.
Only been 4 month's. Only thing I changed was strait pipe no muffler.
Everything that should move does, so I'm leaning to sensor.
I have forscan but am new and don't know if it will measure this vital.
Going to try and clean the sensor first.
