Sorry for yet another o2 sensor thread, I've been reading through the past ones to find what information I could about it and they have been very helpful but I still have a couple small questions. I know I need 3 sensors, 2 front one behind cat, I also found the link for oxygensensorsDOTcom that someone posted, and that looks like a great place to get them, my questions are as follows.

Has anyone changed the sensors on the Aristo? Do we need the same o2 sensors as the GS or do we use the Supra sensors? 1 wire or 4 wire? I think thats all, any answers would be sweet.

Thx all

 

You are going to have to look. It could be 1,3 or 4 wire sensors. My guess is that if you have 3 of them it's 4 wire. I have 1 O2 sensor and it's 3 wire.
