I changed both oxygen sensors in my 2001 Toyota Solara convertible ....?

I would check the connector for any corrosion. These sensors run on a low voltage so are prone to being affected by bad connectors, also follow up the wire and ensure it is not damaged.

then reset the code with a OBD can tester. But, shortly after starting, the "Check engine" light goes back on and the same code 1135 (bank 1, sensor 1, heater circuit failure) gets stored. Now THAT sensor did have a faulty heater. Is there some intermediate component between the sensor and the computer or some other service I must render to correct this problem?

Professional answers, please!
