5 stars for the price and works good
The quality is the same as Deson. 5 stars for the price, and it still works. It prefers to fit with a 2006 Camry LE, change it since Nov 2024, 10,000 miles so far, I drive a lot.

Not worth it !
Purchased it for 2010 Toyota Camry, Code related O2 sensor, we put this item , it didn’t work, didn’t fix the issue, waste of time, waste of money. Later on we throw it to the garbage . Don’t waste your time with this product, if you have a Toyota !

Rav 4 O2 sensor out, no 4 wheel drive
This part was perfect. I bought it thinking I would change it myself and soon realized it was too much of a challenge for me. I brought my Rav4 and the sensor to my mechanic who installed it and now 4 wheel drive is working perfectly. YAY!!

Great generic replacement oxygen sensor
Check engine light came on, so I bought OBD2 tester. It said O2 sensor heater wire at fault, so I replaced both O2 sensors in my 2003 Toyota MR2. Et voila, no more check engine light! Also purchased O2 sensor installation socket, made job easy. So for less than $100, fixed check engine light, saved big bucks over taking to shop.

Cable length Too short. Double check your oem cable first
This sensor does not fit a 2007 Toyota Camry hybrid. The length of the cable is too short as seen in the picture. It will not reach its connection points. Why can’t anyone here say what type of car they’re using it for…
