So i recently replaced my the eccentric shaft sensor since I was experiencing a very "wild" idle. It would spike up and down from 700 to 1500 RPM and then back. I swapped out the sensor and replaced the valve cover gasket.

Everything seems to be running OK but I am still getting the following error codes when use my Carly to diagnose:

What could that mean?

Today I got more of the same with one more added in for flavor.

I welcome any comments on the root cause, suggested fixes or troubleshooting next steps!

Im getting the same. Did you figure this out?

Looks like the eccentric shaft
