EBP Sensor 1813658C2

[Capt. Lowtide]

While pulling the VCs my elbow bumped the Exhaust Back Pressure Sensor and snapped the plastic upper half off. I did a little searching about the functon and can not decide if it is all that neccesary down here in a warmer climate.

Haven't priced a replacement yet, but from what I remember when I sold Navistar parts, the sensors were outrageous. It looked like it was probably stopped up due to soot and possibly not working.

Can I get by without replacing it?

It's not necessary at all for your temps there. I'd probably go ahead & gut it.. I was under the impression that the only "sensor" part of the EBPV was the oil temp sensor on the HPOP res. There is a connection on the drivers side under the turbo inlet that is just the "power" for the actuator. I broke mine off long ago, it just dangles there now, no problems...

Ben, there is also a pressure sensor located in front of the HPOP, a tube comes off the bottom right exhaust manifold and runs to the EBS. Thats the tube that plugs with soot and will make the EBPV close at screwy times also.

But yeah, I agree that Lowtide can probably get away with just unplugging the solenoid and not worrying about the EBPV at all. Gut it at a later time when you have some free time.

Awesome...I love this place. Thanks!

mines unplugged, as well as most other people i know around here in cold icy CT! it doesnt do much other than kill fuel mileage, from my experiences.

but he needs to replace that sensor or replace it with the "dongle". clicky here

 

[Capt. Lowtide]

Thanks for the advice guys, the sensor was located just aft of the HPOP off center toward the passenger side. What is meant by "Gut it at a later time when you have some free time?"

I've read somewhere on here before about the EBPV tube plugging and causing an unsightly drip similar to a leaky rear main seal. I believe that I have that problem now with a greasy fuel looking drip after driving the truck. I have not looked at the tube yet, how is the best way to clean it out?

The "best" way to clean the tube is to just.. Replace it.

Captain -- Gutting it involves removing the butterfly valve post-turbo. Essentially, you are freeing up a bit more of your exhaust getting in the way....
