Oxygen Sensor

[binswood]

I need a new oxygen sensor for my 2002 Avensis GS with the 1.8 VVT-I engine. I'm told that the Toyota part no. is T89465-20740 with a price tag of £185.80 +VAT, not including fitting. A quick Google shows that oxygen sensors are much cheaper in USA, but the Avensis isn't listed at all - lots of other Toyota models, but not Avensis. Can anyone suggest a more affordable alternative to the one I've been quoted? Also, does my car have multiple oxygen sensors, or just one?

i think there are for lambda sensors, as posted before i think they are situated 2 around the manifol and 2 further downt, the donwpipe.

From japanese parts suppliers i think they can be picked up for around £70.

you may need to run a diagnosis/fault codes, to establish on which bank they need replacing
