Hi there, I'm new to forum, but have been following since my first dodge ram.
I have a 2003 dodge ram 5.7, QC, slt, with 285 70 17,
New plugs (not wires), always maintened.
After a week of poor starts, I got these codes today:
P0016 timing, 0440 evap, 0441evap, 0344 camshaft, 0340 camshaft intermittent

What would cause all of this ?
What do I start with first ?
Anybody else have same issues that can shed some light?

 

Welcome to the site

You can search for most of these here on the site and get the resolutions

You can also click the link in my signature below to download a copy of the Service Manual

So far it looks like you should replace the cam/crank sensor and check the hoses at the fuel tank and evap canister

 

Weed is right is right about the evap check and make sure your hoses are all connected and not cracked or lose. I used to get the evap codes when i used a certain cheap gas.

 

I'm going to try replacing both sensors today. Can you tell me where they are located and also where is the evap canister located. Thanks

 

The evap can is right next to your gas tank id post a pic but i dont know how, altough you can go to weeds service manual download it and it shows pics of it, or if you dont want to download all of it you can search the internet for pics on where it is. Many of people have had a problem like this or similiar so there are plenty of pics and helpful advice let us know what you find out.
