That parts diagram is for the 2014 which i think has DEF injection and all that crap. My 2011 exhaust set up is totally different only has 1x O2 sensor and 2x temp sensors (see my earlier post).

I would assume Hamatime's exhaust system would be the same as mine although emission requirements may be different here in the U.K.
So therefore the failing temp sensor can only 1 out of 2 sensors or both.

Sensor in DPF is easy to change, unscrews from canister and unplugs.This logically speaking you would think is sensor 2.
Sensor in turbo is much harder to remove. The DPF will have to come off to gain access to unscrew from turbo.

Don't expect to get any info from Jeep about the fix, if they are anything like here in the UK they will want to fix it ££££££.

Thumbs up

Thanks for your responses guys.

I had the ETC (electronic throttle control) warning light come on today, code P2002. "DPF filter efficiency low". Obviously related.

What does this mean? Should I still be changing the sensors?

I had this code P2002 and ETC light come on last Nov. Turned out to be a leak from one of the DPF differential pressure sensor steel pipes fitted to the DPF canister.
You could get under the Jeep and see if any soot is leaking from the pipe, it will be obvious as it blows all over the transmission.
Or of course i could be a leak in the pressure sensor rubber hoses.

You're right, he was talking about the oxy sensor, but that error is for the temp sensor. So it is likely the one in the dpf, and that explains why he is getting the new error, it won't regen if the sensor is bad.

Thanks. I assumed as much.

The challenge is again, trying to get the part number for the Temp Sensor (EGT) and buy it! Even Jeep spare parts have no idea.

Yeah, they only have details online for the 2014+, because that was when the diesel came out in the US. I'd guess it would be the same part number, but who knows. On the 2014 it looks like 5146662AB is the Catalyst Temperature Sensor, and 5146661AB is the EGT sensor (now replaced by the 5146663AC), going by this TSB:
http://www.wk2jeeps.com/tsb/tsb_wk2_1809415.pdf

Going by the error it is the Cat sensor you want, not the EGT.....
