cam sensor high voltage on new engine
cam sensor high voltage on new engine ok ive done some searching but noone seems to have the same situation i have.
i took a 2008 5.3 block and made an iron block ls1, i put a ls9 cam in it which has the cam sensor on the front of the cover and i put the gto ls1 cam sprocket on it which is on half off half. now i just sent it to texas speed and got it back and now im getting a p0343 code along with some emissions codes. is it possible it could be in the tune? like if they tuned for the wrong sprocket? its a brand new sensor? how can i check the output or input of the sensor?

You can't tune the reluctor count in the computer. That is in the operating system flashed in the computer by GM. The 1x will match up to a 24x crank reluctor. I just did some looking and the '08 5.3L shows to have come with a 58X crank reluctor. Did you change it back to a 24X? What reluctor does the computer are you running? You could have the wrong upper gear on it. You need a 4X upper gear to run with the 58X crank.

spoke to some of the fine people at texas speed and it looks like its resolved now its a 24x relucter with a 24x computer so that wasnt it, they told me to swap to the outside pins on the camshaft sensor extensioin harness and that seems to have it hopefully it dont come back but i can say the car starts beautifly now tho so thanks everyone at texas speed now i just have to figure out why its getting hott so quick i think i have air in the engine anyone know a easy way to purge the air cause im really hoping its not a thermostat bad cause its braand new
Fill the coolant from the upper radiator hose, so that water sits on the thermostat enough to open it. Leave the cap off and run it for 1 or 2 minutes, re-install the cap. Run it to operating temperature, then shut it off and let it cool. Top off the coolant. Repeat.
