The only part of the Lexus AFM that works in the MKIII is swapping housings (haven't I already covered this?). The electronics from the two are different, they provide different frequency scaling per measured airflow. PERIOD.

You're intermittent codes are probably the result of the attempted cleaning or due to the solvents attacking the circuit. Check the wire harness for shorts or too much resistance from the KVAF's harness connector and the TCCS' harness connector. Specifically you should look at E2 and VC. Test the resistance across THA and E2 as per the TSRM. I'm betting on a break in VC, either in the box or the harness.

If you do end up replacing the electronics you wanna send me the old box? I'm interested in dissecting one in person... actually, I'd love to try to rebuild one.
