I live in Arizona and I bought a 2020 ram 2500 bighorn and when I drive up north and stop to get gas the check engine light comes on this has happened twice bother times when I'm up north I'm thinking it might be an altitude issue cause when I get gas in town the light doesn't come on

 

I guess best would be to read the code to see what it's saying? Maybe an O2 sensor is off?

 

This is what the code was

When I plugged the code reader in this is what I got

 

The code was from the first trip up north didn't get to check it this trip light went off before I could check it

 

Good Morning,
Welcome to the site.... My suggestion would be to get it back over to your local Ram Dealer and have them check it out and also so you have a history on this issue. That is kind of a common issue with O2 Sensors... Sometimes it just fuel from where you get it and the computer has to figure it out. Other times it is a real problem and will cause issues later if ignored. With that being said. I would get it back over to the Dealer and have them check it out being the truck is still under warranty, I am going to guess that the dealer is going to have an update for the PCM and a Reflash to address the issue.
Keep us posted...

 

Will do thanks for the advice

 

yep, that's 02 sensor baby... i think ya lucked out!

 

Called the dealership and they can't do anything till the light comes on so I'll have to wait till it dose and take it to the dealer up north

 

well paint me skeptical but i don't think that's true... i hope you get this sorted!

 

I will and let u guys know

 

In that case I would also call Chrysler Customer service and give them your VIN and tell them what the dealer said and ask them to make know of the issue and how many times it has happend to you... That way itis at least in the system that you are having something going on. Just a suggestion.

 

Will do that on Monday thanks for all the help I'll keep u guys posted

 

Well I emailed Chrysler about my problem and what the dealership said hope this gets resolved I'll let u guys what's the out come is

 

That can be the best thing to do... Keep us posted.

 

Well I emailed Chrysler about my issues with truck and what the dealership said no response from Chrysler went camping this past weekend and the check engine light didn't come on so yea

 

See what happens on the next trip?
