Does anyone know if you can switch the secondary o2 sensor with the primary...bc if so my primary is fried and I don't need my secondary Or if there is a cheap place to buy a primary I'm all for that if there is if someone can send me an EXACT link that'd be sweet!

 

The O2 sensors should be the same, performing the same function, and therefor be interchangeable.

The ECU just looks for different readings from the two.

 

It shouldn't be a problem because they have the same plug clips and work the same. When I put in my swap, I only needed to use one O2 sensor because I'm running a 95 OBDI ecu. One of the wires were damaged on the primary so I took the one from the cat and used it as the primary O2. I've never had a problem or threw any codes and that was about 9 months ago.

 

very sweet!!! thank you all very much
