O2 Sensor Heater Malfunction

[eldublu]

Hi.

Engine warning light has come on, error code P0141 - o2 sensor heater malfunction bank 1 sensor 2.

Have reset it only for it to come on a few minutes later so looks like the sensor needs replacing, which one is bank 1 sensor 2 and can anyone recommend the best place to get one (aside from Toyota).

Cheers

H8 (yellow) is Heated Oxygen Sensor (Bank 1 Sensor 2)

H10 (green) is Heated Oxygen Sensor (Bank 2 Sensor 2)

Not sure this applies to your sensor, but maybe does:

Please could someone tell me which one is bank 1 sensor 1?

Thanks

Any pointers would be greatly appreciated as to the whereabouts of
Bank 1 Sensor 1. I similarly have a 2.0 VVTI 2005 model (a 1AZ).

Many thanks
