I have a 2008 cx9 that had a coil pack go bad on cylinder 3 so I replaced and put new plugs than got code p0340 and bought a new camshaft sensor and replaced it but no matter how much I clear code it comes right back. I homed out sensor it had 1.3 ohms but did not see any voltage at harness. Is there a relay or fuse that controls that? Could something have been knocked off when I had plenum off? I’m stuck and at a loss
