1999 Toyota Corolla Oxygen Sensor

Very Satisfied
Reviewer: Dave

Didn't need this sensor, but got it anyway because the pre-converter one was bad (changed them both). Product matched the one I took off my car perfectly from the length and size of the sensor to the shape of the floorboard grommet, attaching clip and connector. Doing a MAJOR tune up on my old car (now my daughters car) because it has 234K miles on it. BTW, I never had a check engine light on this car until it hit 234K with a P0172 (bank 1, sensor 1) CRAZY!!! I now have a 2013 Corolla as well, lol. I have never purchased online parts ever until now and I have one word to say...SLICK!!!

Reviewer: Jesse S

This was the best price for this part I could find for the OM sensor. It was a direct replacement and worked great to put out the darned 'check engine' light after a hard reset of the on board computer.

Reviewer: Exactly what I ordered

Thank you Parts Geek...The descriptions on your website were clear and easy to understand. I have no Auto Repair or Auto Part experience but I knew if I ordered the right part I could get someone to help me get it on the car and save $$$ on getting my car running. It fit perfect and even came with instructions for installing. This will be the site I come to for everything I need in the future. Keep up the good work.
