Worked great for 2007 FJ Cruiser Bank 1 sensor 2
07 FJ Cruiser Bank 1 sensor 2 check engine light code p0038 and p0137 fixed with this Denso sensor. Fit perfectly. I had tried one of the $25-ish sensors that plugged right in and seemed high quality, but after clearing the codes, the CEL came right back on. Decided to buy the Denso since the factory Toyota one I took out had a Denso logo, cleared the codes, and they have stayed off. Worth the extra $20 for sure!!

2003 V8 4Runner
I needed this Denso sensor (Toyota uses Denso for OEM) for an engine light that was due to P0430 (Cat efficiency below threshold). This downstream o2 sensor helped fix the issue. It should be noted that on the V6 4Runner this 02 goes on the driver side. On the V8 4Runner the 02 sensor goes on the passenger side (this 02 sensor is for the passenger side because it has a longer wire). After fixing the issue with the engine light if you still have the VSC Trac/Trac OFF lights perform the "zero point calibration". Would recommend to anyone!

Good quality O2 sensor for 05 Tacoma ( P0420/30 codes )
Easy to install with the correct tool, make sure to get a TEKTON 47749 3/8-Inch Drive by 7/8-Inch (22 mm) Offset Oxygen Sensor Socket. Sprayed the O2 sensors for a day with PB to easy removal. Both Driver/Passenger side O2 sensors came popped of without any issues. Denso 234-4260 and 61 ( drivers side, passenger side ) The driver-side sensor was from open box. Did not function, returned and replacement part received within a few days. No issues with replacment.
