Repeated open readings was the indication of an intermittent sensor. I think you found the problem.

Many generic readers will not decode abs errors. This includes C (chassis), U (network) and B (body) codes. Can your Konnwei reader decode these? My low cost VCX NANO decodes everything and displayed history codes of odd errors not affecting engine running. It's the equivalent of GMs Tech II scantool. I've programmed aftermarket remotes with it.
