Question

I've replaced  numerous parts and i still have the same issue I have other means of transportation but this is my heart. I replaced the cam sensor, coil, icm, crank sensor, pcm and still the same results i took the pcm out of a running blazer of the same year and it still gives the same result. I'm currently taking a look at the wiring and im in desperate need of help and fresh insight on this problem. Any suggestions?

P0336 Camshaft Position sensor "A" circuit  / Range Performance

Check for power for the CKP sensor , With key on engine off, the Pink wire to the CKP should have 12 volts power if that is good, check the ground, this ground is from the computer ground measure with key on engine off, If that area is good you need to investigate for a mechanical condition.
