Toyota Lexus Driver & Passenger Side 4 Piece O2 Oxygen Sensor Set TRQ OSA61643

Easy install But code still shows

So far so good. The error code or the check engine light seems to be clear now. I would definitely recommend picking these up. Price is Right. Fit right in place and plays well with the computer.

Easy installment fit like a glove. Engine light still off! Thanks 1A Auto.

Perfect fit and function !

Excellent price and quick delivery the truck runs great now.

The oxygen sensor for perfect on my 2003 Toyota sequoia I installed them my self pretty easy. The originals sensors cost over $400 and at A1 auto $134. The only thing I did not like is that they are made in China. With that said, I will continue to order my parts from A1 auto.

So far so good. I've had these on my 2000 toyota tundra 4.7 v8 for about a month now, and they are performing perfectly. I was worried at first because the downstream sensors protrude about 1/2" less into the exhaust than original denso sensors. But they are reading just fine. Everything I've used from 1Aauto (TRQ coils, front suspension kit, tailgate latch) has been great. Excellent value and performance.

I had a check engine light come up indicating that I had a bad O2 sensor. The sensors I bought were for a 2002 Toyota Tundra. I purchase a set of 4 to replace all at the same time. I went to a local garage and paid to get them replaced. After driving several miles with new sensors, my check engine light went back on. So, I returned to the garage that put them in and he discovered that the driver rear sensor is faulty. So, I called 1A Auto and explained the situation, no questions asked, they sent me a replacement for the faulty sensor. Other than me having to pay for more labor to get new sensor put in. I am overall happy with product. Customer service is excellent.

I purchased this part for my first gen Toyota Tundra (2004 -2006) after a bank 1 sensor 1 check engine code. Did the part fit - yes. Did the check engine turn off - yesfor a little while. Fast forward a couple weeks and a hundred miles or so and Ive got another upstream code displayed. A little more research and I found out Toyotas do not play well with these aftermarket o2 sensors and youll the same code in no time. Do yourself a favor, forget the cost savings here and get Denso. That is unless you want to buy the part twice and fix the problem again. Believe me, after changing the upstream sensors youll be happy you didnt repeat my mistake.

Replaced all original sensors when one needed replacement at 190k miles. One out of four A1 sensors were bad. Failed after 2 weeks of use. Cost my daughter $400 to have repaired since I could not help her remotely. Replaced bad sensor with Bosch part.
