OEM spec Denso O2 sensor. This is an identical OEM part, so it fit perfectly and performed as it should. Yes, it is two or three time more than some copy, but it is the exact right part, not something generic and the original lasted 20+ years.

I had a check engine light on a 2002 Toyota Camry. Tried to save money by buying a cheaper sensor. Ended up with the same check engine light/error code. I spent several hundred dollars and took the car to four mechanics. Everyone said it was the sensor but three of them said the sensor checked out fine. Finally spent the money on this Denso sensor after finding two websites that said only use Denso or Toyota sensors. Do not think you’re saving money by buying the cheaper sensor… You will not fix it and you will only have more mechanics bills and who knows what kind of damage you may do to your engine. The only issue I have is the wire was about two or 3 inches shorter and couldn’t use the stock wire hold down. But I’ll take it because it fixed my problem!
