EBP Tube

Any one know what reaction would come from a dirty or stopped up EBP sensor and tube? A check and clean is recommended at 60,000 and I have 145,000. Thanks.

I have a writeup in the tech files I think showing you the tube and what comes out of it when it's clogged.

Let me see if I can dig it up.

Is this it MAINTAIN? Removing the sensor and tube
Locate the EBP sensor. It is directly in front of the HPOP on the front of the engine, almost centered. You will want to remove the plastic decorative engine cover to gain access to this sensor.
Unplug the sensor wires by lifting gently outwards on the locking tab while pulling it up. With a little wiggling, it will come out of the sensor body.
Use a 9/16" open end wrench to hold the bracket nut from twisting. A 1" deep socket will slip over the sensor body, allowing you to unscrew the 1/8" npt threads from the bracket.
To break the EBP tube nut loose from the bracket, you will need the 5/8" crow foot wrench. Hold the bracket nut with a 9/16" open end wrench while breaking the tube nut loose with the crow foot. If the nut won't break loose, spray it with a little PB blaster and allow to soak in for 10-15 minutes. Complete the removal with a 5/8" shorty wrench.
The EBP tube nut can be easily reached from under the truck using a standard 5/8" open end wrench. The tube can be removed for this location once the nut has been completely removed.
This is the EBPS tube and sensor removed from the vehicle. Inspect the tube for any obvious cracks or holes and replace as it will not be usable. Check the sensor's opening to see if it is clogged with soot. There is a diaphragm in the sensor so avoid trying to stick anything in the opening more than 1/4" to clean it out. The diaphragm can be damaged and rendered unusable if it is hit with a hard object or punctured.
You can try pushing a wire or old piece of speedometer cable through the tube while spraying in down with brake cleaner. I had some heavy weedwhip string that was rough sided that looked like it would do a nice job.
Once I had the weedwhip line pushed through the tube, I hooked it to a cordless drill and slowly rotated it in the tube while spraying brake cleaner on the line. Once I felt the tube was opening up well, I blew it out with compressed air, sprayed more brake cleaner and continued until the tube was clean. I used a new sensor but if your sensor is clogged, use a small tool to try and dig out the sensor opening but not more than 1/4 inch into the sensor. Replace the sensor if it is packed with soot more than 1/4" down.
Don't forget to run something through the sensor bracket opening and manifold fitting to make sure that they are not packed with soot.
Once everything is cleaned and open, reassemble the parts in reverse order. It is much easier to begin by running the tube up form underneath the truck and starting the tube nut on the manifold fitting. Before tightening the manifold, start the tube nut on the sensor bracket and then finish tightening on the manifold.
Before connecting the sensor plug, coat the weather seal with dielectric grease to keep moisture from corroding the contacts. Since dielectric grease is non-conductive, try to keep from coating the contacts on the plug.

You can do it with regular wrenches. I did, and so does Marc.
