Enhance Engine Performance with 🚀 the Denso 234-9042 Air Fuel Ratio Sensor Review

The original sensor was coated white and deteriorated resulting in a lean fuel/air ratio. The spark plug center electrode insulators were almost white. The engine died when accelerating. Now the engine responds easily to the gas pedal and runs smoothly. The block was perfect for the replacement, right down to the clamp that secures the wires to the bracket from abrasion. Would buy again.

Fits perfectly. There is a PITA to install because it is due to CAT and the car needs to be lifted. Should take a mechanic about 30-45 minutes. Note: Bank 1/Sensor 1 is FRONT/RIGHT This also applies to 2010 Lexus rx350 from 02/2010. What does that mean ? So you look at the 4th digit of your VIN and look at the letter. It must be B or more - B equals February, C equals March. Everything before A is the other part.

Great! You get what you pay for. I ONLY use OEM Denso for sensors on my Toyotas. It was perfect for my 2005 V6 Highlander. It fits bank 2, which has sensor 1 on the front of the exhaust manifold, just behind the radiator. The cable was exactly the same length and the cable colors corresponded to my old sensor. It even included a tube with a copper anti-seize coating. The wiring harness also came with a plastic clip that snaps into the bracket. Perfect Exact OEM Replacement!

Bought this Denso air ratio sensor for my 2002 3.0 liter Camry V6 which had the check engine light on. A local auto parts store did a free scan and found a code P1155, indicating a problem with the air/fuel sensor bank 2 sensor 1. It is located on the intake side of the manifold (front right) just below the air intake. I also ordered an O2 socket. After spraying the old sensor with penetrating lube, I removed the sensor quickly and easily. It took me a little longer to unplug the wiring…

[Supplementary Note 01/05/19] Should indicate this was used to fit a 2007 RX350 Bank 2 A/F Sensor 1 sensor to replace. perfect match, especially when Revain and Google said "match". Well it's about 5-6 inches smaller. Such a shame. Unfortunately I cut the wire too quickly after just comparing the color and shape of the wire. I had to reuse old wires and use black tape to get it working. Not sure if the $50 savings is worth it after all the extra work. Maybe I ordered the wrong part? It would be

Perfect fit for 2007 Lexus RX-350. on the bulkhead side, in front of the catalytic converter! Definitely requires a special deep socket with one open side to remove and replace without damage. Most of my other Lexus and Toyota O2 sensors could be replaced with an open-end or ring spanner. However, I could not find a way to get the standard key in the place where sensor position 1 of bank 1 is and could not use the standard key in such a bottleneck. Bought a special open deep socket and replaced

I had a check engine light on a 2002 Toyota Camry. I tried to save money by buying a cheaper sensor. I ended up getting the same error/check engine light code. I spent several hundred dollars and handed the car over to four mechanics. All said it was the sensor but three said the sensor was fine. Finally spent money on this Denso sensor after finding two websites that said they only use Denso or Toyota sensors. Don't think that you're saving money by buying a cheaper sensor... you won't fix it…
