Might be a magnetized crank trigger inverting the signal? The sensor could be inverting the signal as well, depends on what style it is? Make sure the grounds are in the correct place and clean.

Yes you make a great point Bernie Thompson has a couple of videos with magnetized camshafts… this signal though is on the crank shaft… it is worth a try… thanks will keep you posted

Thanks for including the picture of the trigger wheel — it shows not the missing tooth, but one long tooth. Typically, presence of a tooth makes the sensor pull signal low, so I would expect the “verus picture“ from such a trigger wheel, not the “Hyundai’s sample”. Also the fact that it idles fine makes me think the ECM is OK with the “verus picture“ CKP signal, but, of course, can not be…

I see what you are saying about the missing tooth being a long tooth but the higher “bumps” at each end of the tooth have me wondering. How much gap, wheel to sensor, is needed for the sensor to change state?

Not sure if this pertains to your situation, but often the camshaft gear pin shears and causes the cam to shift. This is common on the V6 engines. The theory is the high pressure fuel pump may start to drag, and sheer the pin

Yes a lot of the Hyundai cam sprocket pins do shear will have you scratching your head for a few

We need Ray Yergeau with a known good !!😉
