I'm getting an intermittent engine light on my Dodge Journey 2009 RT 2.7V6. Performance doesn't seem to be affected in any way. But I'm suspecting a faulty gas cap?

 

Post the code and we might be able to help. The car is telling you what's wrong.

 

I wish I could. But diagnostic equipment and OBD tools aren't easy to come by here. And very pricey.
I tried getting the codes to display on the dash but I'm not sure if my model supports that feature.

I used to own and Opel Astra and could get the fault codes myself. This is a new journey for me. Pardon the pun.

The car is going in on Monday for the dealer to fix some stuff and they will sort that out. I would just like to know how to diagnose these issues so the mechanics don't sell me some BS story in the future.

 

You can buy a code reader for less than $20 these days off amazon or ebay.

 

Just a quick update on this one. I actually replaced the EGR valve and that has sorted the MIL light. (for now....)
