I checked my trouble codes by turning on/off my ignition. What i get is (P done) Am I geussing right by thinking that this means there is no trouble codes?

 

yes P done = no P codes
BUT is the check eng light on...?
why did you check?

If light off - and your just checking, no drivability issues , your done don't worry be happy

ps model year is always helpful

 

01 1500 5.9

just found out that i could check it by the ignition switch and just had to do it. I thought that is what it meant, just wanted some reassurance.
thanks

 

Now that you feel all warm a fuzzy! LOL Check the plenum and have the cat checked, before you do have a CEL.

 

LOL , just never heard of checking trouble codes like that and just couldn't hold back from doing it LOL Yeah I've been reading the posts on plenum repair and seriously looking into it. OK, are you talking about the catalic converter (CAT).

 

Nope, these trucks came standard with a feline companion in the back seat. Why, didn't you get one with yours?

J/K. Yup, cat = catalytic converter. The broken plenum leaks oil into the system which will eventually ruin the cat and the O2 sensors.
