2014 NOx Sensor Question - Competition Diesel.Com

Gdogg · 01-16-2020, 07:22 PM

So I have a 2014 3500 CCLC 4x4 dually here and I have a code P2201NOx module #1, P1C55 NOx bank 1 sensor, P2202 NOx circuit 1,

I was under it and only see one NOx sensor, I know some diesels have two.
The only one I see on this truck is on the inside of the frame rail back by the rear axle and is part # 68085740AA

Does anybody know if that is sensor #1?
If not where is it.
Does this have 2 sensors?
Normally I don't ask these questions but I have a hip problem and I'm in extreme pain and couldn't stay under this track any longer.

Thanks

There's one on the side of the block, ahead of the turbo.
The sensor itself is mounted in the cast downpipe adapter, follow the wires from that and you'll find the module itself.

It’s been awhile for me but I could’ve sworn there was one in the down pipe too but maybe I’m not remembering correctly.
