This oxygen sensor can be installed easily and ensures longevity.

Review: 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!!
Review: 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!

## Questions & Answers

**Q: Is this item work for 2007 Toyota solora 6 cylinders?**
A: The Toyota Solara has 2 downstream o2 sensors (and 2 upstream Air Fuel Ratio Sensors).  This part ( 234-4261) will fit the front downstream application.  The rear downstream sensor is part# 234-4064.  You first have to make sure which sensor is bad.  Then, If you go to Denso auto parts.com, you can see all the applications for your vehicle before purchasing

**Q: Is this the right sensor for Bank 2 Sensor 1 Installation?  I think that is front driver side?
Thank You**
A: This part is for either Bank 1 Sensor 2 or Bank 2 Sensor 2 (the sensor after the catalytic converter).  Sensor 1 is the sensor that adjusts the air/fuel mix.  It is before the catalytic converter and will likely be a different sensor type.  Best to double check first.

**Q: Will this fit my toyota tacoma'06 pre runner 4l. engine?**
A: I installed on a 2002 4runner.  Not sure if it will fit your vehicle.

**Q: I own a 2002 4Runner with a sensor that needs the flange; it cannot be separated. Does this come with the flange?**
A: I have a 2002 4-runner,it has two oxygen sensors,the one here and also Denso #234-9002 shows it fits this vehicle and it has the flange.
