Cascadia 2016 code light

Type of engine? Also, post a picture of how the check engine lights look.

 

Looks like thats a voltage issue to the NOX sensor, I get those once in a while. It only take a split second of a loss or surge of power to set off a code and are generally harmless but may indicate there is a problem with a harness or maybe the ECU. See if you can clear the code and if it comes back. You should be ok to make your trip. Also did this code happen to pop up while it was raining?

 

This “may” apply to your truck—but you may not need to do anything, depending on which check engine lights are appearing. I need to see the check engine lights, among other things that I’ll mention once I see the images.

 

Did you see two check engine lights initially? Your truck seems similar to mine. On the DD15, you get two amber check engine lights. One will usually disappear in a few seconds. What you have now is just a note to the driver that a problem was detected. This light should disappear on its own after 3 driving cycles. No need to go to the dealer. If it doesn’t disappear, then go to the dealer.

 

Just wait for 3 driving cycles, and it will probably clear on its own. If it doesn’t, then take it to the dealer. Sometimes there are mechanical and electrical glitches that occur for a few seconds and never come back. Don’t worry about those. I think each driving cycle needs to be for a certain amount of miles (maybe over 10 miles). Who knows. Just drive as usual and wait for it to clear.
