Denso 234 9057 Fuel Ratio Sensor Review

I had to buy this because the other one I bought from Advanced Auto didn't arrive on time. This was cheaper and worked. My Lexus ES330 is happy and has no engine lights.

Very well solve P0031. Easy to swap out yourself, just leave the car on the jacks the night before and do it first thing in the morning. This is much easier when the car is cold. The exchange took only 10 minutes.

I was skeptical about buying this part from Revain, but was I wrong? Once this part was installed on my ES 330 the check engine light was gone! I passed the exam, my stress level went down. Thank you Revine!

Fix the mysterious MPG drop with no check engine light on my Lexus ES330 with 261,000 miles (3mz-fe). After doing everything the blogs recommended, I finally spent the money to replace all the O2 and air/fuel ratio sensors. Now 267 kmpg is back to 22.3mpg in a week.

Firstly, the plastic side does not have the cut outs required for the original parts. Even after some adjustments it fits, but the check engine light does not go out. The pedal is still firm as expected, slightly softer and the mileage is still the same. NOTE: Machanic, as Reson product is not original, therefore does not affect the check engine light.
