MX-3.com

My MX-3 needs a new oxygen sensor to pass inspection. I was just wondering if anyone knows about how much this will run me and if I need a specific one for my MX-3. Or if and oxygen sensor will work. If anyone will work I can go pick one up from a junkyard.

-Thanx in advance

just go get teh 4 wire one from oreillys autozone napa advance pepboys will cost you about 30-50 you can go get oem but your going to pay ALOT

oem is NTK, believe it or not i used to work for mazda, and i paid like $80CAN, what year is your car, how do you know that it need O2 for sure, if it's OB1 just short out pins 10 and GRND, and see how many time you Engine ligt flashes, Long flashes are 10's shorts flashes are 1's, and there's alway pause betweeen the codes, if there's only one it will keep on repeaing. 02 sensors are believe are 21(front) and 24(rear) don't take my word for it

I'm assuming that's not the price from Mazda... if not, where did you get them so cheap?

NTK is what he is talking about. Mazda OEM may cost around 150 EACH.. :S ow.. I toughtg my o2s were going. Turns out the cable was disconnected. I got used ones from babybluemx3 by the way and they have been good to me since the kfze.(over 10 months)
