Review on Denso-234-4368: High-Quality Black 🔌 Oxygen Sensor for Optimal Performance by Sam Lund

Prices verified and Revain was the lowest price I could get in a reasonable time. I read to stick with Denso gauges, so I did. Replaced the sensor today, no problems with the sensor. PB Blaster on the old one had an O2 socket on it for 20 minutes and it unscrewed quite easily. Apply anti-seize (which came with the new sensor) to the threads and screw in the new one. I connected the cable and started the car. I erased all the codes that were in the computer. The clamps that hold the O2 wires are probably the trickiest. I broke the top one (on purpose) and removed the two bottom ones, removing the little support holding them up so I can open them up to a spot where I can see them working. To open the clips you have to use two small screwdrivers to unlock the teeth from either direction, so getting them out of the car was a much better idea for me. I tested the new O2 along with bank 2 sensor 2 (not replaced yet) to see how they compare. The new sensor responds much better and more fluidly, the old sensor seems to jump on the signal a little more often. For now I would buy again and am happy with the results and performance of the sensor. I hope this helps someone who is hesitant to do this repair themselves or to order this part from Revain. By the way, I didn't get anything for this review.
