Hey, I'm running a 5S-FE Celica with the original oxygen sensor from 1994. My mileage reads about 397,000 km (250,000 miles) ... my question is "Should I change my sensor?" -- it hasn't beeped or told me to change it..

Why? What are the benifits.. What should I get..?

Thanks

Shaun

If it aint broke, don't fix it. Save up for your swap >>

If it's working don't change it. A new one will cost you at least $60 for a crappy universal one, or $250 for a OEM toyota one that is easier to replace. IF your o2 sensor is old and not working, all it would do is make you run rich or lean unless you have a piggyback computer in there.

thanks for the info guys!
