Paccar rumored to delete emissions because of parts shortages

I did some figuring and other than things like the exhaust manifold and water pump, things that could go wrong on any engine, just strictly emission related issues I’ve spent roughly $1200 on two separate NOx sensors and $2400 for a particulate filter. $3600 in roughly 3 years doesn’t seem unreasonable to me.

 

Define days lost. As far as being under a load and away from home today is the first time. The first NOx sensor and DPF were when it was in for a couple other things and I was gone for a week spending time with my girlfriend. Originally told them to clean the DPF because it had been about 200k since it was cleaned the first time. I was told they weren’t happy and didn’t think it was cleaned good enough so I said to replace it.

The second NOx sensor I ran for the rest of the week with the MIL on until I got it into my home shop. It was last Feb when we had that cold snap and it was below zero all week. Once it was fixed I left it parked for the rest of the week anyway.

This time it looks like a week until they can release the software update.

This is the first time I’ve been at a shop other than Peterbilt at home since I’ve had this truck.

 

I understand the desire to have better, cleaner engines.

I understand the desire to have a reliable engine and not go backwards in reliability and longevity of an asset.

What still blows my mind, is that after all these years, the new engines still do not last like the old. We are supposed to move forward, not backward. Somebody should be able to design an engine that is environmentally friendly and last like a Cat 3406.

 

Now why would they do something like that. They are in the business of selling new trucks.
Built to last a short period an replace

 

Technically the part in question isn’t an engine part and isn’t related to the longevity of the engine. It’s the def quality sensor/def level sensor in the def tank.

 

Yes you have to run def. The NOx sensors will control the emission stuff same as they did prior to 2016 when they put the def quality sensor in the tank. I’m assuming the gauge won’t work however, but I don’t know.

You assume correct. The software change ignores the sensor. The DEF gauge will be left innoperative. The DEF level will still need to be maintained as the system is still operable to maintain emmissions control.

Is your unit Paccar or Cummins?

 

I have the MX13.
