Hello, so the timing belt was changed about 10,000 miles ago and I was diving the other day it through a p0344 code. So I changed the crank sensor with oe sensor and gave same code so I changed cam sensor and it through a p0016 code. So I put old sensor back on and the p0344 code came back so I got a different mote expinsive cam sensor then it thru the p0016 code so I put old crank sensor back in no change still p0016 code. So I replaced the impulse magnet for the cam sensor still p0016 code and I tried to put old cam sensor back in and instead of it giving me the p0344 code it gave me the p0016 code. So the new cam sensor and new magnit and crank sensor are in still throws the p0016 code and when the old cam sensor in and the code was p0344 would not go over 2300 rpm, but now with the p0016 code it will go to 3400 rpm and start like it dose when it hits the governor. Any input would be awesome. Maybe new wire harness or ECU. I don't know but the timing marks ad on still I checked that.

Good morning,

The 16 code is for cam/crank correlation which means the marks are off.

I attached the marks for you to verify. Sounds like you need to either replace the belt or adjust the tensioner.

So if I drove the car for say 2,000 miles with no check engine light and the belts in the same spot it was after change how long dose it take the computer to see that is off? Because we checked the belt timing marks and there in the same spot they were when we changed it.

It will see it right away. There is no time that it has to take to set the code.

So I can clear the codes and drive for like a mile and then it throws a code and it can idol and not throw a code could a bad wire make it do that. I heard that there is wiring that goes underneath the exhaust manifold that if it melts or the heat will brake the wires down could that be causing this. I heard to that there is a update for the computer that in some cases it will give a false p0016 code. I know I drive it 60 miles to work and back with the check engine light on and it does fine if the timing was out I wouldn't be able to do that would i?

The PCM sees something wrong and when it does, it defaults to those settings.

Did you remove the front cover for the belt and verify the marks?

Can you do a compression test to verify?

I took it apart to down to the belt after it started throwing the code I thought that might be it but all is lined up and verified I guess my next step is wiring seeing if I have a wire failure somewhere. Because it makes no sense I can put old sensor in and run the car for 2 days with out it throwing the code. I put be sensor in the car and it throws the code with two different new sensors.

I know it looks like I am beating you up with the timing, but it is not a sensor. You are stuck on a sensor issue.

This code indicates the cam and crank are not lined up correctly.
