Fixed check engine and VSC light on Lexus IS250
Mark A. Johnson•February 16, 2018
Great fit for my 2008 Lexus IS250. Only difficulty is removing the old sensor! Really awkward placement that the Lexus dealer will charge you $700 for changing. A good mechanic with some specialty access bars/ratchets and a can of thread penetrating lubricant can do it in about an hour. Fixed the check engine light and VSC light only Lexus IS250.
Tried the Ebay garbage and those threw codes

Used this for my 2006 4Runner V8 Banks 1 and 2 Sensor 1 (front). Tried the Ebay garbage and those threw codes. These are genuine and worked great! You can trust these in your Toyota that likes REAL Denso plugs.
Right Price, Right Sensor, Happy Driver!
Why yes, I do own this•August 12, 2017
2006 Toyota Tundra Double cab, 4.7 L had check engine light with codes P0136 and P0138 for a malfunction and high voltage on Bank 1 Sensor 2. Doing some research I found quite a few people that changed the front sensor (the Air/Fuel ratio for sale here) and this fixed the high voltage/out of limit warnings for the downstream sensor. I used ABN 3 Piece 3/8" Drive Oxygen Sensor Wrench Socket Set to swap it out, but any good O2 wrench should work.
After about 2000 miles still no issues!

DEBBIE L.•July 10, 2017
Fit my 2005 Toyota Sequoia SR5 4wd. Had an error code P0136 and P0138. First replaced bank 1 sensor 2 (driver side rear). This did not correct the error. Then used this sensor to replace Bank 1 sensor 1 (driver side front) and have not had a problem since. Removing old sensor was a challenge. Need to use a special socket that can be borrowed with a deposit from Autozone. Also helps to spray lubricant on old sensor at least a day before removing. Due to location unhooking clip took some manipulation.
One of the four sensors I purchased was used sealed in a bag.
Cewing•May 21, 2017
One of four oxygen sensors I purchased was clearly used but in a sealed bag. The other three units were not counterfeit which is good but purchasers need to immediately open and confirm the contents of the boxes as there are clearly some quality control issues on returns for this product.
