O2 Sensor Fuse - 2.2 - 2003 Alero

[pappyl]

Getting a bad heater code on my downstream O2 sensor.

Does anyone know where the fuse is for the O2 heater circuit? Not labelled on any of the 3 fuse blocks (think its shared circuit).

Maybe the sensor - but want to check the cheap stuff first.

Thanks

dont think its fused

It's not.

They are like $65, not that bad. Could probably get a cheap on on eBay, just make sure it's already put together

Not a bad price.. "www.amazon.com" is the cheapest option that will actually ship to Canada.. it comes to around $91 shipped to your door. Still probably better than an Authorized AC Delco Dealer.

No fuse? Cripes there are so many damn fuses on this car but they didn;t fuse the O2 sensor WTF is GM thinking?

I'll check into the ordering online... They are enough $.

I've not been under there to take it off - Am hoping this bugger cooperates - I broke an O2 sensor wrench on one of these before.

I owned the car for probably 3 years before I figured out that there was that third fusebox on the passenger side.

That maybe they would need to add another fusebox if they needed another fuse????

I had my car for 3 days nd had to go through all 3 fuse boxes to change blown fuses
