Help. I have a 2008 LT 2.2 manual.
Car died last week, got a code reader and read a p0341 and a p0335.
replaced them both, now it is still kicking out a p0335 and a p0336.
pulled the valve cover and verified timing chain is good and timed correctly.
fuel pump and pressure is good, battery is good, grounds look and feel solid. New plugs. Help

 

What did you replace?
P0335 & P0336 indicate the crankshaft sensor circuit has a problem. That should not inhibit starting. Both of them require the engine to be running.
Likely a wire problem, what happened just before it died? Any work done under the hood?
Has the fuse box been removed ever? Might be those 4 bolts in the fuse box need tightening.

 

Replaced both cam and crank sensor. Tried starting today, rechecked timing chain, timing jumped a tooth, looked further into motor, need new tensioners. Got em on order. Goona replace cam chain and both tensions tomorrow. Thanks for the help, let ya know what happens. Happy motorin' .😎

 

The chain jumped a tooth should have triggered a code .
let us know after you replace the timing chain and balance shaft chain, guides and tensioners.
