I was thinking it may be easier to dump the ECU fault codes and see if the machine also thought this was the problem (since I guess they are ultimately be connected...). I'll have a look this coming weekend.
Thanks again

That's probably a good thought. However, I have seen situations where the older Camry's ECUs (OBD1 systems) didn't pick up everything. I had an 86 Camry 4 cylinder that was having a problem, that I eventually traced to a bad O2 sensor, even when there were no fault codes present. I would check for trouble codes and if you find 1 or more present, then you know what needs to be corrected. If no codes are present, then I would still check the ECT sensor with a DVM.
