Denso 234 4015 Oxygen Sensor Review

Fits 2004 Lexus IS300 Lower 1 Sensor Block. The dealer wanted $350. Tip: Spray on WD40 the night before. Also, the replacement has a longer shaft than the original, so you'll need a longer head to install it. I ordered the Cartman Automotive Oxygen Sensor Socket Set 10PC for $30 and it saved the day.

My 2005 Lexus IS300 was giving out code P0037 which is an oxygen sensor code for bank 1 sensor 2. The check engine light was on and the lane deactivation light was flashing with a bad sensor. I bought a Denso sensor and it goes very well with a bank 1 sensor 2. The length of the cable is perfect and it comes with anti jam. After the replacement, the code is gone and the check engine light is off.

The Denso 234-4015 is a direct replacement for the Lexus IS 300 B1S2 oxygen sensor. Denso is the OEM of the sensor. Making this repair is easy, but the oxygen sensor socket makes it even easier. Do repairs when the manifold is at ambient temperature, no need to run the engine to warm it up as some blogs suggested. If the old one is stuck, try a PD Blaster or WD-40 and rock the sensor back and forth to remove it. Use anti-seize material on the new sensor.

This is the perfect replacement part for my 2003 Lexus IS300 bank 1 sensor 2 oxygen sensor. When I bought this part from Revain and did the job myself (ie through my dad who loves to tinker with cars) I saved $550 compared to shipping it to my local car dealer! They wanted $260 for the part, $125 for the labor, and $100 for the initial diagnosis (excluding taxes). At Revain, this Denso replacement sensor was $200 less. I've had the replacement part for 3 months now and it works great!

I rarely review Revain products but I just felt compelled to review this product! On my 2001 Lexus IS 300, the bank 1 oxygen sensor 1 failed. I was at a loss because this part would cost me $300 plus dollars to install at my shop and the Lexus part alone would cost me $238 if I did it myself. I tried my local auto parts store, but the wire attached to the sensor was too short - not to mention it cost me $114. I found this oxygen sensor at Revain for almost 1/3 the price of the factory version…

I had the infamous P0440 along with other codes on my 2002 Lexus IS300 which turned out to be a low flow sensor for bank 1 sensor 2 or b1s2. After reading about the sensor problem I decided to go with the plug n play version and not the generic sensor which requires cutting and splicing. I've done this in the past with great success, but I just wanted to get it done quickly and the Denso 234-4015 is a direct OEM replacement. Denso is probably the main supplier of all imported JDM vehicles. So…
