1 wire VS 3 wire VS 4 wire O2 sensors, interchangeable??
Are any of the different styles of oxygen sensors interchangeable? The 4 wire O2 sensor on my daytona went and I'm wondering if I can swap in one of the single or 3 wire O2 sensors I have laying around rather than buying another one? I was under the impression that the 3 wire and the 4 wire were both heated, just that the 4 wire had an extra ground? And I thought even the one wire was useable even though it's not heated. I know I should just spring for a new one, but money is money and I have the sensors in the tool box. Anyone???

Yes, they are pretty much compatible, except the connectors are different. The three wire doesn't have a ground circuit for the sensor element so it grounds through the exhaust manifold which isn't as good and could potentially throw the reading off by a tenth of a volt or so. The one wire isn't heated so it takes a bit longer to warm up. You'll have some splicing to do though, since the connectors are different between them.

I finally have a good excuse to convert my SL to 4-wire. Thanks for the link Clay.

Well I'll just splice the three wire one in for now, but can't beat that price for a new one, and hey, new is new.

Wow. 100% positive on 2700+ feedback!

Just swap the connector from the bad 4 wire to the 3 wire. You will have an empty cavity for the sensor ground, which is no big deal. The O2 volts will be a little lower now that the 3 wire grounds through the swing valve....... I would say to get a 4 wire when funds permit...........
