Hi every one, I´m from Argentina, I have a RAM 1500 5,2 2wd, in good shape, I´m from Argentina.

My question, is confusing to me to get the fault codes, I been playing with the second O2 sensor to extend it cause the cat is off, and the ligth came on every week, but I did the extension and the ligth came on after 5 minutes and the truck started to run funny.
Here´s the video, if someone coult point me out the fault codes for me, and any tips will be welcome
Sorry for my bad speeling but I speak spanish

 

12 Battery was disconnected at some point.

21 O2 stays at center..... doesn't tell WHICH one though..... one of your O2 sensors is shot. If you have replaced the rear sensor, time to swap the front.

55 End of messages.

 

As a result of the blown plenum and a clogged cat of course.

 

Thanks a lot!!, I changed the number 1 O2 sensor and is running excelent!! I did it myself.
Another question, if the second sensor is with out the extension, will te ligth came at some point on?
Thanks

 

Maybe.

Some folks run with no cat, and don't get the light. Others have to do the non-fouler trick to get the light to stay off. There is a do it yourself in the faq section for the non-fouler trick.

 

Neither one of the o2's are going to last last very long, with the most likely bad plenum gasket. Gutted or eliminated cat.

 

The gasket is new it has 30 days and the truck has 162000 km or 100,000 miles on it, the cat is empty. We dont have any restrictions like you do on emissions

 

You think it would have been a good idea to add the fact that the gasket was replaced? Anyway, heres the DIY for the non fouler trick (available in the very comprehensive FAQ/DIY section)

BTW, was just the gasket replaced, or did you replace the pan also? https://dodgeforum.com/forum/2nd-gen...um-thread.html

 

Sorry, I don´t understand very well the expressions.
Thanks any ways
