Take it back to Toyota and have them check/replace the thermostat.

So you are saying if ECT sensor and O2 sensor have been replaced and those codes are still showing it might be the thermostat?

Not any more...it has been discovered that Toyota has inadvertantly misdefined that code. Read it as a P0032...HO2S Heater Control Circuit High (Bank 1 Sensor 1).

So if I read P1150 & P1155 (after CAT) and P0125 (ECT) but all have been replaced it should indicate Bank 1 Sensor 1? Of course that is the only one that I haven't done and it is the hardest to get to!! Thanks for the information.

In order to rule out a thermostat and ECT sensor, I would read the coolant temperature on the scanner as well.
