If you do a search through the threads this pops up from time to time...

an oxygen sensor is a sensor which by a magical method detects oxygen... it's changed by putting it in the place of the old one.

WTF is an oxygen sensor???

[jaxx]

oxygen sensor is on the exhaust system, one before the cat and one just after

it, yes, detects oxygen coming out the engine and calculates wether the car is running lean or rich and then tells the ECU, which in turn modifys the fueling

if its nackered then toyota is ya best bet, but expect to pay about 150quid

i know its around 130 for the mr2 and thats only got one!
