"I have a 2001 Toyota Avalon. Got the P155 code for malfunctioning Bank 2 Sensor 1. Found this part. Said that it was an exact upstream replacement. Didn t work on this specific car." posted by: Richard on March 30, 2014

"O2 sensors are expensive. The cheapest I could find the regular Denso sensor is $150 this one is less than 1/3rd the price. The only issue is that you need to use the old sensors wire harness - which is a common failure point. So check the old wire harness before purchasing this one. Also the sensor comes with crimps which I think would fail over time. The best bet is to solder the wires and use a liquid electrical tape or something similar to keep road grime and dirt out of the wires. If you go through the effort to do it right then I think the sensor will last as long as the regular Denso. Also as a side note this is a Denso sensor so you are getting a quality O2 sensor." posted by: Matt on February 24, 2014 view all 127 reviews

"Part performed better than expected. Improved idle and gasoline milage" posted by: O on April 7, 2009

"Its never easy to install an O2 sensor on the back side of a motor, but with all the wires attached to the main housing, once you get the old one off, and the new one installed, its a snap to hook up and it instantly starts reading correctly with cars computer. If you have basic mechanical skills, you should be able to do this repair on your own." posted by: Mick on March 25, 2009 view all 4 reviews
