Did you replace with a Honda OEM sensor or a 3rd party sensor?

as far as sensors go, I never found a 3rd party sensor that the D17 played nice with. Also, handle that sensor with care, it's a finicky little thing. Don't drop it, overtorque it, etc. Was working fine, did a timing belt job, dropped it during reinstall from maybe 8-12", threw a code upon starting, replaced with a new OEM one. Did a head gasket job after that, everything went fine until reinstall, accidentally put a bit too much torque on it, threw a code, replaced with a new OEM one. Any job I did after that where I had to remove the CKP sensor, I treated it like a princess, and had zero problems.

Corrosion at the CKP sensor harness and wires? Liquid (coolant) trapped in connector? Harness connections loose and not making proper connection to sensor? Wa this after a timing belt service? I believe advice is to not disconnect the harness at the CKP and just remove bolt to move our of way when performing timing belt service to avoid CKP problems.

Update oem sensor didn't make any difference

You will probably want to check engine timing then. It may have jumped a tooth.
