Downstream Oxygen Sensor - Compatible with 2007 - 2014 ES350 2008 2009 2010 2011 2012 2013

Fast delivery of the product. It was exactly as described as it was the right part for my vehicle. Replaced it with the part received and the o2 sensor light never came back. I definitely recommend this store and would use it again for my next auto repair needs.

The part was good and arrived in a timely manner. However due to my own error I ordered auniversal part without the pigtail. I prefer not to use this type of part as it is easy to mess up. Make sure of what you order. My overall experince with Parts Geek was good and I would not hesitate to purchase from them in the future.

The product "1998 Toyota Sienna Denso Oxygen Sensor - Upstream Denso 234-4209" is exactly the right part of my need, it arrived on time and contain all the necessary hardware to do the repair job and the fast shipping make everything so smoothly connected . It is a happy experience, I would recommend my friend to use the service when they need.

Seems ok just a bit hard to trim the wires to fit to the old unit harness . It's a non direct fit where you have to make sure you have the correct wires otherwise damage to you PCM may happen. Other than that it's a good sensor if your good with electronics and electrical :)

I was very satisfied with the Denso o2 sensors. The wire colors were a match for the factory units and cutting and splicing the connectors was easily accomplished with a low budget strip/crimp tool. Each came with a tube of anti-sieze compound that should insure easy removal later. 5 stars!

We were ecstatic when we found this part available for such a great price. It was almost half what the local auto parts store wanted. My husband happens to be a good, on his own learning, mechanic and was able to fix it for us.

The past came in much faster than expected, the installation was a little difficult, due to the position of the wires. Overall the last is great and my car is running better than normal.

I bought both an upstream and downstream Oxygen Sensor for my Honda CR-V and both fit great. I opted for the universal sensors and cut/soldered my own plugs on the harnesses. The wires were more than long enough but were difficult to solder due to the wire itself. Not sure why, but the solder didn't want to bond to the wire like normal copper. Regardless, they are working great and I would recommend these.

this is the part that i had to wire myself. it should have clearly stated on product spec that a buyer has to wire the part. I had to spent an hour doing this job. Had I known this, I would have chosen different part. Well, since I have replaced the part successfully, and since there's no more trouble code, i'm happy.

I own a 2005 Toyota Camry Base Model. This oxygen sensor does not come with a connector. I used the connector that was already on the car. However, my check engine light is still on yet the jerking has ceased and the ride is smoother. Therefore, this part does fit the base model 2005 Camry but it doesn't come with the connector. I needed the oxygen sensor so I had no choice but to place the sensor on the car. Just wanted to let know that it doesn't exactly fit. However, I was very satisfied with the speed of delivery of the product. It was very quick. I was happy with the price and speed of delivery. I will probably order from this site again.
