Why do so many Americans hate European trucks?

Both or just the after catalyst NOX sensor?

For those who don't know a EPA10 and younger trucks have 2 NOX sensors.
1 before and 1 after the catalist.

 

A hammer can fix that.......

 

I have replaced about same amount of both upstream and downstream. MX used to use redundant lambda sensor, but was phased out in 2016. It helped with troubleshooting, but was pricey. Haven't replaced many of the O2 sensors. Out of warranty we replace them as pair. Knock on wood, we haven't replaced any SCR catalysts yet. Nox sensors operate around 1400 degrees F, so life isn't forever!

 

Tell me about it............................found out today.
560€ 630$ outlet sensor.
"no CAN communacation with sensor"
According to DAVIE most likely the module part off the sensor was the problem.(did some research and those sensors are linked to their module,making them 1 unit)
Good news is no soot or dirt on the sensor.

 

I wish. LOL

 

They offer a reman ones over here. About $400 a piece.

 

New ones are....$?

 

FYI while researching i came across a youtube off a Freghtliner getting a new outlet sensor.
Guess what.....................it looked 100% like mine.
Continental seems to be to supplier to several brands.

 

Do you have davie...?

 

$600 give or take $50. Couple different variants. Continental seems to be into everything. They build Paccar's ACM (after treatment control module). Dorman is starting to offer some aftermarket.
