TRQ oxygen sensors are manufactured to precise specifications using premium raw materials to optimize your vehicle’s emission system. Each sensor is isostatically-pressed for improved strength and durability, and plasma-sprayed to improve sensitivity and prolong the service life of the sensors. Oxygen sensors wear out over time and should be replaced every 60,000 miles to prevent poor engine performance. TRQ recommends replacing the oxygen sensors in sets to optimize fuel economy and reduce overall emissions. All products are fit and road-tested in our Massachusetts R&D facility to ensure we deliver on our promise of Trusted Reliable Quality.

Saw many videos on youtube and this has helped me out on many occasions/ very down to earth and practical help for even an average backyard mechanic. encouraged me to fix it. I bought this sensor from them because of it. This one I could not do because I needed a special tool to do it. It is a good thing I took it to my local trusted mechanic because fater changing it out for only sixty dollars, he needed to reset the check engine light. All is well and no additional charge for the check engine light. This fix was for a 2001 toyota sequoia 2wd bank one sensor one. Thank you 1Aauto. I like you folks

I purchased this part to clear the check engine light on my 2004 Tundra. Thanks to the video, I was able to replace the part quickly and easily. The price was also lower than what I was able to find at local auto parts stores. Very happy with my first purchase from 1A Auto and will be coming back to them in the future.
No more fault lights

Quality Replacement Oxygen Sensor

I installed this sensor to replace a faulty Bank 1, Sensor 1 (pre-cat, driver side) in my 2003 4.7L Tundra. The code is cleared and the sensor seems to be working properly. Once I gained access to the sensor and had the proper tools, replacement was fairly easy and straightforward. I applied some extra antiseize to the threads, as the applied antiseize on the sensor threads was a bit skimpy. Seems to be a good quality part. Ordering and shipping from 1A Auto was easy and fast.
Great product and attention to detail.

Exact part. Fixed my Check engine light. When I was under the vehicle changing it I realized that I had forgotten anti seize. No problem with this part! They had already put some on the threads before shipping. Very nice attention to detail! I love 1a auto's parts. No complaints yet.
