2014 Ram EcoDiesel error code P0428

[CFMopar]

Hey guys,

Figured I'd ask this question on this board also and hopefully there was a mechanic here that could help answer it.


I recently got my truck back from getting some paint work done and I'm getting error code P0428.

I'm using my bluedriver OBDII reader to pull the code. I reset it and drove it while the scanner was hooked up and pulled the freeze frame data from the moment the code came up. I'll post it below.

Besides just telling me what sensor is throwing the code (im assuming its the 02 sensor? I did replace it earlier this year so odd if its happening again.) Just curious so I can learn to diagnose better in the future. What data do you see from the freeze frame that stands out as irregular? What data would you live stream to see it happen in real time for that code? And of course what should I do to fix it

Thanks a bunch

What areas of paint work did you have done? Could wiring in the area of paint be disturbed?

It is! That's what I get replying to a message early in the morning with a headache!

When all that fancy diesel emissions stuff starts to go, be prepared to open your wallet.

Why are your Bank 2 sensors showing -40f?


Todd

Yeah I did see that. Also noticed the Exhaust Gas Recirculation Temperature Bank 2, Sensor 2 : -40 °C, -40 °F
