Fit ok.

This went into a ’99 4Runner, a 4WD non-California / Federal model. The Amazon part finder insisted it was inappropriate for my application, but the Denso part finder correctly specified it. Be aware that the lead is approximately 6″ shorter than the OEM O2 sensor’s lead, and this difference requires some maneuvering to snap the connectors together on the exhaust side of the transmission, not the driver’s side where the OEM molex is to be found. I bolted up the sensor first, to keep it clean and free of damage, then fiddled with the molex. Pulled the EFI relay to reset the system, since it’s a new part. No CEL code during a 10-mile test drive.

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.

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

My CEL (check engine light) had recently come on in my 2000 Toyota 4Runner. I tried a couple other interventions before finally deciding it was probably from a dead oxygen sensor. This particular vehicle has an “upstream” sensor and a “downstream” sensor. The sensor is the same for both applications (they are juts in different parts of the exhaust system). I only replaced the upstream one (for now). It fit as OEM. Fairly easy to do, although I did hit the old one with some PB Blaster the day before to loosen things up so that may have helped. I have read they can be tricky to remove sometimes. The whole process probably took less than a 1/2 hour. I then disconnected the negative battery terminal to reset the vehicle’s computers, then reconnected it and fired it up. CEL light gone and performance restored. My mileage is not where I think it should be and it is possible the other sensor also needs to be replaced, I will purchase this product again when that time comes.

Received the item via regular shipping in 3 business days and in excellent conditon. My Tacoma has 4wd and standard 5 speed transmission. The Denso oxgen sensor was a perfect fit. My pocket scanner had been showing an engine malfunction code of P0125. Initially, for several months, the engine malfuction light would come on, my scanner would show this code, and I would erase the code with the scanner which caused the light to go out. The engine light would not come on again until 50-100 miles later. Recently, the light started coming on after the engine temperature gauge warmed up to normal operating temp. I think the sensor was telling me that it was completely shot. Some website posts were suggesting a bad thermostat for causing the problem. But, the new 234-4162 Denso oxygen sensor immediately fixed the malfunction. My truck, as do
most, has two oxygen sensors (one in front of catalytic converter and the other behind it). I replaced the front (upstream) sensor which is closest to the engine and the one most likely to go bad. The sensor comes with a top quality gasket but no nuts. I purchased two stainless steel nuts to replace the two that were rusted. The total cost for the sensor was $74.21 which includes taxes and shipping. Autozone was asking $105 plus tax.

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.

Exact Denso part the manufacturer uses. Works perfectly.
I strongly recommend not buying aftermarket (either brand or Denso etc) and my service states the same.

Although there are some differences from OE, the sensor works as it should. My application was for a 1999 T4R Limited 4×4 auto with Federal emissions.

Used for my 4×4 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
