Hi all, curious if anyone has seen this, I'm new to coyotes. 2021 Mach 1 is throwing a MIL for P0345 Cam position sensor bank 2. Datalog shows what appears to be a loss of cam control after initial warm up. Bank 2 intake cam varies much more than bank 1 and I assume after much of that or varying too far off course it then pops the fault code. Once the fault code is set it parks the cams at 0.
At cold start up (first graph) you can see the bank 2 intake cam (4th line) is not as steady as bank 1 intake cam (3rd line) which follows the desired timing (2nd line). You can also see the duty cycle for bank 2 is much more active than bank 1, bottom two lines.
After warm up (second graph) it appears to lose control or just give up and then fault sets, top line.
Is this a classic bad phaser on bank 2? I ask because this engine only has 8k miles but its not 100% stock. We built an aluminator clone short block for it using the GT500 oil pump and pan. That pump has a higher pressure at all RPMs than the stock pump. Could this be giving me issues? You'd think both cams would be unhappy if that were the case.
Background - Engine was rebuilt due to a spun rod bearing which was caught fairly early. Phaser screens did have a small amount of debris. New screens were installed and cams and heads cleaned. One head with scored journals replaced, other head was ok.
Thoughts? Appreciate any insight you might have.
Thanks, Mike
