"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
