Default P0343 code
I have an early 1998 Pontiac Trans Am with the ls1. I just put a new engine in it with 30 miles with brand new sensors and it’s throwing a P0 343 code. We have good voltage to the cam position sensor. Any ideas?

Could still be a bad (or defective) sensor

Check all grounds and check for chafed or poorly connected wiring.
