Denso 234-4261 Oxygen Sensor with 4-Wire 10” Harness for Lexus/Toyota V-6 Downstream Left/Front

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!!

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!

Perfect length. Good quality and cheap enough that if it stops working you can just buy another. Easy to put on if you have an older car use spray to be able to break the rusted bolts if not it is plug and play. Works well quality is good. Denso makes great stuff. Removed the codes I was getting. No issue with sensors. Well made. No more 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.
