I'll try that (it's easy enough to do), but I don't think it will help since the LH2.2 controller isn't a "fault code" controller like the LH2.4 controllers are, and I don't think it has continuous power for memory retention (pin 4 on the LH2.4 controller gets 12v all the time, but there's no pin like that on the LH2.2 controller).
I tried another AMM and I get the same result (CEL on). Funny thing is that the car seems to run just fine with the light on, with either AMM. I tried disconnecting the AMM with the engine running (to force "limp-home" mode), and got the normal surging idle that goes with that, and it smoothed back out when I reconnected the AMM (but light still on).
