Hey guys just got done installing MMR motor and now I keep getting P0340 and p0344. It's an 07 so I think my alternater is good, I already changed the cam position sensor and same thing. What could be causing this I need help!

may be a grounding issue

measure the resistance between the
engine and the negative battery post

I thought they fixed this issue with the 07's... Your alternater is not generating enough power. If you ingnore this issue, you'll end up with a dead battery soon. Its under warranty and there is a TSB on it.

I thought in 07 that they fixed the alternater issue? Everything seems to be working fine, Im stumped and I don't want to take it into the dealership.

i threw the P0340 code last night too. i sprayed my giggle juice to test out the higher jets. as soon as i stopped my car, turned it off, then turned it back on, it threw that code.

what year is your car? I don't understand why that error keeps coming up I double checked all my connections.
