Face Plugged DOC

[Shotgun74]

Thank you guys for all the information.

I'll check the DOC when I get back out there. I have to check my maintenance records. I'm certain that I changed the IMAP Sensor in November 2016 plus I changed the one on the top of the engine passenger side ( I cant remember the name of it) in February 2017. I know that means nothing as parts can fail prematurely.

I'm sorry guys I'm just not that knowledgeable about all of the different sensors but I'm learning the hard way. I love how knowledgeable & sharing of their time everyone is on this forum. Reminds of the times when guys would stop & assist others alongside the road.

They claim the fault code was because the sensor was giving eratic temperature readings due to the doc being plugged. I'll check to see that the dpf they put on last week is in fact new as well as the doc. They said the doc was most likely at the end of its life & will go completely soon. They're surprised that it wasn't throwing a code.

I told them that I thought an emissions pm program would visually check & then clean & or replace parts/sensors as needed.

Either way I'm beyond frustrated with all of it but willing to learn better proper ways.

Thanks again guys for all the input.
