TheBrian Posted April 15, 2005 Share Posted April 15, 2005 http://mymiata.paladinmicro.com/Miata4-WireO2.htm#O2SensorTesting This site describes how to test an oxygen sensor. Basically, heat it up, adjust the amount of oxygen while watching the voltage. I haven't tried it, but I hope you find it useful. Quote Link to comment Share on other sites More sharing options...

Forget it, get an OBD2 interface and test it in situ with the engine running! Safer and less work involved. Quote Link to comment Share on other sites More sharing options...
TheBrian Posted April 15, 2005 Author Share Posted April 15, 2005 True, but that requires $55 and a laptop. Though the in situ testing would be a huge advantage. Quote Link to comment Share on other sites More sharing options...
Tiny Clark Posted April 16, 2005 Share Posted April 16, 2005 Man, If I had a fairly high mileage vehicle, I wouldn't go to the trouble to pull it out just to test it. I would R square it with a new one. Quote Link to comment Share on other sites More sharing options...
