Check Engine showing Cat converter problem

So, I did a little mudding yesterday, and right when we were about to leave my check engine light flicked on....I had it taken to autozone and they ran a check on the codes and said that the first(front) catalytic converter was throwing an issue.

Any thoughts? Would a big puddle cause that to happen? Should i just wash down the car and wait until it goes away, or is it just coincidence and I need a new cat.

The symptoms of a bad cat, aka poor idle, rotten egg smell do not exist.

Thanks for the help!

 

possible an o2 sensor gone bad it doesnt sound like you have a bad cat if you dont have symptoms

 

try pressure washing the whole truck and letting it dry first. its possible a sensor got good and wet and tripped the cel for that code.

 

Had the same issue last week.Erased the code and came back on the next day.I'm still covered under the emission warranty so the stealership will be replacing my cat Wednesday.

 

Dude take it to a mech and have a full diganostic ran on it first before you spend any money on a new o2 sensor.. second they will tell u which one it is such lower bank O2 sensor but have it diganosed by a comp not a scaner because i was about to spend the money $180 on one sensor and found out it was just that it had gotten dirty due to muddin.....

 

^^^ did you have to reset the ecu get the check engine light to go away or did you just wash it and it went away by itself ? I plan on getting a full diagnostic this weekend to figure this out before I drop any money

Thanks for all the help so far!

 

Ya i had it cleared but autozone wont do it
