Review: EXACT replacement for Toyota OEM unit - 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.
Review: Better buy this one if you have a Camry ! - 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!

### ⭐⭐⭐⭐⭐ EXACT replacement for Toyota OEM unit

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.

### ⭐⭐⭐⭐⭐ OEM Denso!
*by E***V on April 30, 2019*

Awesome!! You get what you pay for. I ONLY go with OEM Denso for my sensors on my Toyotas. This was perfect for my 2005 Highlander with the V6 engine. It fit Bank 2, sensor 1 which is at the front of the exhaust manifold, directly behind the radiator. The wire was the exact length and the wire colors matched my old sensor. It even included a tube of copper anti-seize. The wire loom also came with the plastic clip that snaps into a bracket. Perfect exact oem replacement!!
