The tube is routed from a fitting on the front of your passenger side exhaust manifold and then wraps up infront of your of the engine to the ebpv.Which is located just oabove the water pump and uder the hpop resivior.You can clean it with a wire clothes hanger.Mine was rusted at the exhaust manifold and needed replace.Check to make sure you can get it of in one pice before full removeall.You may want a new tube on hand.I had to make one but they are $25 at the dealer.

 

Yep, they get plugged from time to time and here is how to fix.

If you need parts the part numbers are:

Exhaust Back Pressure Sensor 4C3Z - 9J460 - A

Exhaust Back Pressure Sensor Tube 1C3Z - 9D477 - AA

 

thanks for all the help
every one on here is wicked nice

 

I cleaned mine out, WOW, a BIG difference in mileage...like 3MPG. Wasn't hard to do.

 

If tube is cracked or has holes, you can fashion a new one from steel brake line that can be found at any auto parts store. $4 for line, +$9 for flare tool, and +$4 for tubing bender = $17, new part from dealer= $40


Hint: the fittings and collars on your old tube are trasfered to the new tube, then flare the tube ends.

 

is there any way to test the sensor to see if it is working properly, I took mine off to clean it and had a hole in the tube. Replaced the tube with some brake line from oreilly and cleaned up the sensor as much as I could but it had a lot of debris in it. Just want to make sure the sensor is working properly.

 

I just got around to finally replacing my EBP tube and sensor. Not an easy job, atleast in my case. The nuts on the tube was really rusted on there pretty good. Not much room to work with especially with a big lifted truck. I was basicly standing inside the engine trying to reach the tube mounting bracket.

Ended up getting it out and man was it packed solid with soot. Hard as a rock.. thankfully I had a replacement tube because there was no cleaning it out. Put the new tube in,,, didn't exactly match up none too good (had to bend it slightly to work), put new sensor in.... and watched my MPG increase immediately between 3.8-4.2 mpg.

Very very happy with the end results. I was originally getting 10-11 city and 14.5-15.0 highway....... Now with the new EBP sensor and Tube, I'm at 13.8-15.2 city and 17-19 highway.. esptimating highway since I haven't done too much highway driving yet.

How often should the EBP tube and sensor be cleaned?
