Check engine light driving me nuts 200

I had a similar problem with the temp senser. Turned out to be a poor ECU earth connection which for some reason is connected to the manifold. It measured 3 Ohm to earth. Since it seem to be the wire, I made a local connection to earth and it solved the check light issue.

Since all measurements are taken from earth, a slightly faulty earth creates an incorrect reading.
