Oxygen Sensor Downstream 2006 2009 Calif ESV Review

I recently bought this Oxygen Sensor for my car and it has been a great addition. Thanks to my knowledge gained in practice replacing the old sensor with this new one was a breeze... The sensor has improved my car`s performance, and I appreciate the ACCURATE readings it provides. The only downside is the slightly higher price compared to other sensors on the market, but the quality and performance make up for it..

later UPDATE: Wait a minute! Maybe it doesn't quite work. The original sensor definitely didn't work, it worked within 3-4 miles. This one worked great aside from the weird random low voltage loop I mentioned in my original review. About 650 miles of my trip, straight on, just a few 15 minute fill ups, code reset, I checked the sensor while driving on level ground and it stayed at 0.251 volts. I accelerated a little and he came back to life. Another 200 miles and again not, but again I refrain…
