exhaust sensors

Installed spartan and dpf/cat delete today....Is really nice, but did not want to play to much as I messed up two sensors. I need to know starting from the front of the truck to the rear what the sensors are.

I messed up the 2nd sensor from the front which has a vacuum type hose over it and is a larger sensor than the other three. I broke the rubber hose and assume will have to buy the new plastic box with the rubber hose coming out of it to go on the sensor. The sensor is fine hose just got torn off right at the little box.

I also can't get the 4th sensor out ( the one closest to the muffler) I am going to try the torch tomorrow and get this one out.

Thanks for any help

the 3 sensors that look the same are exhaust gas sensors, and that last one is a *****. My dealer charged me $103 for it. the other is a pressure sensor and i can't help you there. I had no issues getting mine off.

I dont know how you can break a pressure sensor. Once you take the bolt off that holds the bracket it just slides off. I went ahead and bought three new egt sensors for mine so I can just leave mine in the dpf (plus I couldnt get the rear one out) I could probably have got it out by heating it but I heard that ruins them so I just left it.

i held the bracket with my hand, turned the bolt loose and it came right off... i don't know how either

The rear EGT sensor can be difficult to remove. If you spray it with PB blaster or any other penetrating oil, put vice grips on it and smack the grips hard with your hand, it usually gives and comes right out. The pressure sensor can be a pain if you don't unbolt it and give it a little turn to break the connection on the nipple coming from the exhaust.

I have seen a few that just absolutely refuse to come out, most have 50+K miles on the trucks. Torch, hammer, vise grips, sledge hammer, you name it won't budge them. My stock DPF is one of those still has the sensor in it till this day and only had 3k miles on it when I tried to remove it!
