Default P0344 wtf!

So I changed the camshaft sensor and crankshaft sensor and I am still getting the camshaft dtc. Am I missing something? I've done the ecu reset and it still comes up. Replaced all four o2 sensors as well. It won't switch into overdrive nor will it downshift when I step on the gas. I can floor it and it just gradually speeds up.

Damn. Does this mean I have to take it to the dealer? Thanks for the reply by the way.

*****Update*****

It turns out there was a boot that slid off my coil pack. The wire was still plugged in but the cover was off. There was some sort of wire pack under the hood leaning against the open plug causing a short of some sort I guess. I put the cover back on and everything fixed. No dealer! I guess I need to pay attention to details more haha.

That's good you found something. Let's hope the unrelated cam code doesn't come back.

Since I changed the camshaft sensor and the short was happening after that would that trigger the code?

I must have knocked that cover off somehow when I was changing the sensor.

Your original post makes it sound like you got the code before you changed the sensor, so knocking a boot off the coil pack during cam sensor replacement would seem unrelated to the code. A shorted plug wire would be more likely to cause a misfire code.

It's running fine now, though. That's all that matters.

Guessing is expensive, cheaper to take it to the dealer, less aggravation too..
