Denso234-4162 Oxygen Sensor with 4-Wire 10.5” Harness for Non-California, Non-4WD Lexus/Toyota

Worked great. OEM parts for Toyota Truck

Perfect fit and great OEM quality. perfect match for my Toyota 4Runner

Great price for OEM sensors that work perfectly. After reading forums, it was clear to only use the original brand and model sensors on my 1995 Tacoma 2.7. These worked great!

Used for my 4x4 4runner although it says it doesn’t fit, it’s actually the correct part / number for my application. Install was easy and haven’t had any issues since

I just replaced mine with Denso O2 sensors 2 years ago. Replaced them all. This one failed fast considering they normally last 10 years for a OEM equivalent part.This one is easy to change IF your exhaust system is not that rusty and has the new 2 bolt attachment. You can watch a YouTube video on how to replace or A1 auto video. It took me 5 minutes to replace this BUT truck is in Arizona, 4WD so I slid right under. 2 bolts to take out. Then replace. Always use a gasket.

They fit perfectly! Haven’t driven it much since I replaced them. Hope the CEL doesn’t come back on.

As described. This is for bank 2, downstream on an 03 Tundra.My truck is running much better.

Edit 11/20/23: MAF still working nicely. Yes on the Hitachi and yes on the Denso O2 Sensors. Dew it Grasshopper!!!Had cleaned the original MAF Sensor a few times over the years, but still couldn’t remove the small amount of black carbon on a few of the delicate inner sections. Stealership wanted $175 for new one. Sourced the manufacturer to Hitachi by looking at the snap on cover of the original MAF on the engine. Sourced it back to this store along with New Denso o2 Sensors.Ordered and installed the MAF 6 months ago along with 4 New Denso o2 Sensors. Engine is much torquier! MPG is slightly better now due to the combination of MAF and o2 newness.Tested the old MAF per Toyota FSM Spec and it was out of spec. Same with the old o2’s. After almost 20 years guess it was time? Truck was purring nicely before swap (even being out of spec), but man that awesome torque has come back that I remember when she was new. Engine is even smoother now. The 4.7L rules.Side notes: Looks like Hitachi grinds off the Toyota stamping for branding issues. Sensor doesn’t look used/remanufactured as stated in another comment above. Looks like the exact part as the original. No worries because the original cap pops off and snaps over the New Sensor. Also the cost is $55 vs $170. Made in USA!Denso is Made in USA quality. Comes with Copper Anti-Seize. Suggest buying Lisle Thread Chaser to clean up the threads on the front o2 sensors. Also, a sensor socket is good to have for swapping out the fronts. May want to purchase some new nuts (4) for the rear sensors as the old ones are most likely rusted/deteriorated. If one of your o2’s is bad, suggest replacing all 4 at the same time and be done with it. Restore that sweet torque.

No hay nada que agregar los sensores Denso son los mejores que he utilizado en mi Tacoma en cuanto hice el reemplazo se noto la diferencia. Los recomiendo ampliamente no se arrepentirán.

Direct replacement for front o2 sensor, put out the the cryptic P0125 code and drasticly improved fuel milage. No filing out holes, no stretching of harness. Fits like OEM

Nice to be able to use OEM quality parts at a reasonable price that fits the requirements. Also Denso delivered promptly and the customer Help department was top notch, nice to deal with knowledgeable and friendly people. I highly recommend this supplier.

Original denso 100% lo recomiendo y en lo personal lo compre a un super precio

I have a 2003 Tundra 4.7. I had changed the sensors twice with same problem returning each time. Finally found out Denso makes the ones that came with my truck. I changed all 4 and now for the first time in 4 years no check engine lite for 2 weeks so far. My take on it is if you want the light out get the Denso if you have a Tundra!! Do it right the first time. Almost 1/3 better gas mileage as well..big bonus!
