exhaust temperature sensor

[blue dragon]

Anyone remove one of these yet? Did you do it from the top or bottom? I'm throwing a code for temperature sensor before the SCR. I bought a replacement, but can't figure out how to get at it.

Im assuming you want to know where the electric connection is?
the temp sensor you can unscrew with the exhaust on but to get to the electric connector located next to the transmission above the exhaust you have to drop the exhaust and use a long thin head flat screw driver to lift the clip and pull it.

There is not a lot of room to work there so it's a bit of a struggle to get out.

Im talking about the temp sensor next to the first nox sensor and right before the scr.
