not to hi-jack but i cleaned mine last night. had build up from he.ll in it. got the tube cleaned pretty easy and the sensor to. but how do you know if the sensor is bad. i think i read not to stick anything more then a 1/4 in into it but when cleaning it my pocket screwdriver bottomed out in the sensor about a inch into the sensor. is the sensor bad or is it suppost to be like that.
Boy after reading this, did I ever get lucky. 205k miles, it had never been removed. The sensor came off with very little effort, tube was nearly whistle clean. I put the new sensor on anyway. But of course I have to wonder why some of us have clogged up ones, and mine was nearly in perfect shape?
Just a complete guess on my part, but I've noticed most of the complaints about the dirty ones came from guys with low mileage. I'm guessing the higher useage helps keep things cleaner.

Maybe. I drive mine a lot, a lot of long trips, very seldom do grocery getting with it and never beat it. I can go 6 to 7000 miles between oil changes and the oil on the stick is still honey colored. My Cat 3208 and very first PSD (95) would change the oil black black after only 1500 miles. Go figure.
I am thinking of doing this also. However, like others here, I just don't know if it's necessary yet. I have 130,000 miles on my 01, and so far I've seen only a slight drop in mileage. Don't know whether it is from Winter blend fuel, or ?

Sounds like a PITA if it doesn't need it though!

PITA??? I would guess from my experience today if it come apart really easy it is probably just fine. I gave mine a heavy dose of PB about 4 hours before I even tried taking it apart. I used the backup wrench, but may have been able to do it without it.
Well...answered my own question. The backet covers a hole that is access to the HPOP gear drive so I do guess it serves a purpose. I sure wish I had just taken that barcket off (with EBP tubing) and taken the tube off on the bench. That tube nut was so d#^m tight it took me and a buddy a little struggle with some breaker bars to get it off.....and that was when it was no longer in the truck. Had I taken the bracket off first, I wouldn't have bent it and would likely be driving now instead of waiting for a new bracket to arrive. Oh well...live and learn.
For those doing this job....two small bolts get the bracket off easily....rather than using a crow's foot wrench, another wrench, 3 arms and some struggle.
I was well aware of this. Which is why I started the thread in the first place. I even tried to buy a new tube from the stealership yesterday expecting the worst to happen. They did not have one in stock. They will now though cuz I ordered one just in case.
Chemicals and heat work well. Force leads to disaster. Better to not get it off first go around than break something.
I sprayed mine, brought engine up to temp, shut it off and sprayed again, then went to work after it cooled a bit. PB is great stuff. Best bet is to spray the fittings the day before, then again the day of the job.
I had to spray mine 3 different times before it would loosen. I have 110k and mine was fully clogged. I found a new sensor on Ebay for I think was $25. My fuel mileage increased 1-2 mpg. I cleaned the tube at first but didn't like it that I couldn't get it spotless so I bent my own tube.
I've done this cleaning on two different trucks and believe it should be part of regular maintenance. I found that for me the use of the crow's foot was a PIA and that a open end wrench was much easier. Both tubes were clogged, one tube had holes and had cracks. Couldn't see or feel the damage from below. One truck has over 200,000 and the othe truck is approaching that mark. Make sure you take off the serpintine belt and PSD cover on the HPOP.

100% agree.
I have 88,000 miles on my truck and the tube was burned through, wide open.
The sensor was so filled up with scaly crud that I didn't even try and save it.
I just bought a new one.

I see this stuff and it just blows me away. I did not remove the gingerbread, did not remove the belt and was completely finished in less than 10 minutes. To me this is one of the great mysteries of the PSD. I had never even considered looking at mine until reading all of the horror stories here, so figured I would look. Although I did not win the power ball last night so I ain't all that lucky, and I'm on my 3rd transmission.
