06 ram 5.7 rough idle and crank sensor
Asked by Rohloffjake518 Oct 31, 2017 at 08:15 PM about the 2006 Dodge RAM 1500 SLT Quad Cab RWD
Question type: Maintenance & Repair
I have an 06 Dodge Ram Hemi that is hard to start
unless I give it gas. Once it turns over, it has a
rough idle while in park, as if it's going to stall. I
have replaced the crank sensor twice and I am still
getting p0335 crank sensor code. I have also tried
wiping the codes and it comes back right away.
Any ideas? I also see a check gauges light.

One of the causes for a crank sensor code is off-timing due to a worn timing chain. A worn guide or tensioner can let slack into the timing chain. The chain itself has a considerable service life span, but those plastic guides and tensioners are weak links. You may also want to look at your valve train - lifters, rockers, and valves/springs. The rockers can pop off or a valve can drop, those can throw same codes as it puts timing off. You can check compression to get an idea if a valve is hanging open. If you pop the valve covers and turn the crank by hand you can also get an idea if there is slack in timing chain.

I don't hear any clicking or chirping, when I'm in park the engine fluctuates, while driving I can't go past 10mph but the ebbing doesn't rev past 1000 rpms.
wow , we are having the exact same problem. our 2006 dodge ram 1500 hemi 5.7 will only drive 10mpr. I have no knowledge of repair. over 50hrs of research, PLEASE WILL SOMEBODY TELL US THE CAUSE, PROBLEM & SOLUTION? thanx jazzy
Check the wires where they come up around your oil filter headed up the front of the engine that's what was wrong with mine they were bare and shorting out
