2007 Mazda 3 2.3 Calif Emission

Install it in under 40 min. Engine light turn off after 4 time turning it on. It's been about a month and so far light hasn't turn on. Remember if your car has Calif sticker under the hood, it will have 2 sensor after cat, one under between passenger and driver side and the other one is going to be around the middle of the car. USE JACK STANDS when getting under the car.

Is this upstream or downstream sensor?

Look at the connectors they are different between the upstream and the downstream. Same sensor just different connections as far as I could tell.
