Amazing! Cleared codes!
Genuine denso part (makes OEM parts for Toyota) at a great price. Installed on a 2005 Tacoma V6 4x4 and it fit great. Wire was perfect length and the quality is superb. This sensor cleared my P0128 and P0606 codes. I highly recommend. Super easy to install yourself, just purchase an O2 sensor tool and PB blaster. Attached are photos of the 20 year old Denso sensors and the wire connectors (again, for a 2005 Tacoma) so that way you Tacoma drivers can ensure this is the correct part for you. Thanks!

The one I got was authentic. works and fit great.
234-4260 is a Direct fit for O2 sensor for 2009 Lexus ES350 sensor Bank 2 Sensor 2 aka Downstream Left. Whoever confused of which sensor it is this is it. I got it confirmed it's Denso authentic the one I have received. It looks more updated than the original denso from toyota denso that came out of the car. As of now it is going great and easy to install. Sensor looks high quality and it was on sale on amazon so the price is amazing.

Fit 2007 4Runner V6 driver’s side, closest to ground.
Worked great on my 2007 4runner with the V6. Fit on the drivers side, closest to the ground. Took all of 15 minutes to install. New threads even came with a little anti seize on them. Installed, cleared codes, codes did not return.

Saved myself a ton of money by replacing this sensor myself. Easy job and connecting it was simple.

Cord too short & wires exposed
Cord is way too short & wires are exposed. That black “cord” there’s 2 wires in there that are exposed by at least one inch. Unfortunately, I didn’t act quick enough with a mechanic to install it, so I was outside of the 30 day window to return it. Ever since I’ve had it installed, my car doesn’t idol like it did before the installation

Excelente producto
Excelente producto, la verdad hizo que mi vehículo aumentará el rendimiento del combustible, y más que nada que si es original, la verdad no hay nada mejor que denso para Toyota, lo use en un Toyota Camry 96 3.0, Banco 2 sensor 1.

Excelente.
El sensor llegó en su caja y bolsa sellada, no tiene marcas de haber sido usado, se ve que sí es original (marca y matrícula grabada en el cuerpo del sensor, cables y conector robustos).
