The engine shold be cold to do this, (first crank of the day).

Hook a multi meter (voltage meter) up to the o2 sensor.

Crank the engine and rev it to 2500rpm, or immediately start driving. The voltage from the o2 sensor should be hitting .45-.5 volts, and it should be fluxtuation several times a second.

If it is not, replace them both with splice in generic units.

are the oxygen sensor in your car is 1-wire style? I dont know which one I should buy.

I would not try and compare an ES to a windom when it comes to emmision related parts as Asia has a totally different set of rules to play by. You may have only one wire on yours from the factory as you also do not have an EGR either.

A 3vz-fe is a 3vz-fe.

Same thing, they just don't have EGR & the ECU runs a little leaner with a little more timing.

Toys have you physically looked at a 3vz from japan?

You want pics from before, or after it got dropped in the mr2? :D
