820-00165 Booting but fan spinning high

This had some liquid-damage in a few spots. I've cleaned up all the bad/burnt components and repaired some traces. It boots fine but fan spins up. Known-good trackpad/cable and DC-In board/cable. I'm getting two errors in the built-in test: SMC - PFM006 and camera - PPN001. I've checked every trace, pad and component around the SMC and all are fine. Resistances and voltage-drops to ground are all normal. Not sure where to go next. I attached pre-cleaning pics.

Camera error would point to an issue on the SMBUS_SMC_1_S0_SDA and/or SCL lines. Diode mode them and inspect every component they go to. Crap under SMC possible too.
