DOES ANYONE KNOW WHAT A P0340 & P0335 MEANS?

 

When you type in all Caps it means you are Yelling.

Have you tried typing this into a Google search:
Dodge Ram P0335 & P0340

First link I got was......
http://dodgeram.info/tsb/2004/18-002-04.htm

 

Go to this link, https://dodgeforum.com/m_691136/tm.htm, and it will list all the codes. Everybody should bookmark this link or put it into their favorite’s folder. It will come in useful to everybody someday. Red

And don’t yell; use lower case when asking questions. Thanks.
