    I have not contact the seller, that will come next
  

*by D***K on Reviewed in the United States on January 18, 2014*

I purchased this as a replacement to the Denso factory unit. However as soon as i put this unit in i started having problems it almost seems like the sensor is not calibrated. It got worse and worse with running rich. After 6 days of having it in now it reads 0volts 50% of the time, changes very sluggish and gets worse the warmer the sensor gets. It is making me run a 9.0AFR at idle (0Volts) I have to take off my whole down pipe 3 hours of work to switch this unit out and now am forced to go buy one from the local stealership because my car is not drivable at the moment. my 2 cents, stick with factory parts aka denso they may be more money but apparently worth it. To give a little bit more info i have a 2008 Scion XB Automatic

    Works like it should...
  

*by D***R on Reviewed in the United States on April 7, 2014*

I tried some off ebay and while the unit worked, the Fuel Air module did not. Tried two from that seller... This was what was actually needed. It is both a Fuel/Air and Oxygen sensor as required by my vehicle - a 2006 Toyota Highlander. With the right tool, change out is quite simple. Without it... what a pain in the ..... Any way, if this is what you need, This is a good buy.
