Toyota 4Runner Celica Pickup T100 O2 Oxygen Sensor TRQ OSA61171

Works as it should

Satisfied

Oxygen sensor fit perfectly and worked perfectly! Will use 1A for all my auto part needs!

Garbage. Stopped working within a week of installing. Buy quality parts not cheap TRQ parts. Total waste of money and outside of the return window

First of all, 1a auto did an fantastic job helping me recover a lost package. Their customer service is excellent! That being said, this O2 sensor does not fit the 2000 tundra as I was led to believe. The O2 sensor itself has a flange fitting that does not fit in the upstream sensor position (bank 1, sensor 1) I was able to remove the flange for a proper fit of the O2 sensor into the exhaust system. I then Cut the factory connector off the old O2 sensor and soldered the wires to the new O2 sensor. I installed the new sensor, cleared the code and everything seems to be working well.

EASY INSTALL, DONT FORGET TO TIGHTEN THE SENSOR INTO THE BRACKET (ITS THREADED) BEFORE YOU INSTALL ONTO EXHAUST SYSTEM, ITS MUCH HARDER TO TIGHTEN ONCE ITS MOUNTED. MY CHECK ENGINE LIGHT IS STILL OFF AFTER 600 MILES AND TONS OF CYCLES. SO I THINK THIS WAS THE CULPRET! LOL

Works just the way it should

works. no c/e light.

the fit was perfect and the online videos were a great help on how to replace it.

I have purchased from 1A Auto before and found their prices and shipping to be the best around. Part looked and works just like the Big name shops and their national brands.
