Hi
I have 2000 Toyota sienna LE (.0L V6 FI 24V ( 1MZFE ) 2995cc). It has about 165,000 miles on it. The check engine light is on. Mode 3, Static errors:
*P0155 O2 sensor heater circuit
(bank 2, sensor 1)
I think these mean I need to replace o2 sensors. Is there any way to tell which ones?
Could something else be causing these codes?
The van runs fine, and fuel mileage has not dropped off. Thanks for your help.

Bank 2 sensor 1 is the bank on the radiator side and the sensor before the convertor.
