Our take on the Denso Oxygen Sensor 234-4705

The Denso 234-4705 is a downstream (post-catalyst) oxygen sensor built as an OE-style replacement for a range of Nissan vehicles. Denso supplies sensors to carmakers, so this part matches the factory connector and fitment rather than needing splicing. It suits owners chasing a check-engine light or failed emissions test caused by a lazy or dead rear sensor. Against generic universal sensors, the direct-fit plug and Denso's OE background are the main draw; the trade-off is that it only fits the specific Nissan applications it is listed for.

Pros
  • OE-quality sensor from a major factory supplier
  • Downstream position, direct-fit connector
  • No splicing or universal wiring adapters
  • Accurate air-fuel feedback for fuel economy and emissions
  • Common fix for catalyst efficiency and slow-response codes
Cons
  • Fits only the specific Nissan applications listed
  • Downstream only; not a substitute for the upstream sensor
  • Sensor codes can also stem from wiring or the catalytic converter
  • Requires a proper O2 sensor socket and some access work

What reviewers say

Owners of compatible Nissans generally report the sensor plugs in like the factory part and clears oxygen-sensor codes. Complaints center on fitment confusion and on codes that return when the real fault is elsewhere.

What people mention
  • FitmentMixedSome buyers find it a direct plug-in match, while others order the wrong application for their Nissan.
  • Code fixPraisedOwners say it clears downstream oxygen-sensor codes when the sensor was the fault.
  • BuildPraisedBuyers describe it as matching the factory part in quality and connector style.
  • DiagnosisCriticisedCodes sometimes return because the real problem is wiring or the catalytic converter, not the sensor.

Questions and answers

Is this an upstream or downstream sensor?
It is a downstream sensor, mounted after the catalytic converter. Do not use it in place of the upstream sensor.
Will it fit my Nissan?
Fitment depends on the exact model, year and engine. Check your vehicle against the Denso 234-4705 application list before ordering.
Does it come with a connector?
Yes. It is a direct-fit sensor with the factory-style connector, so no splicing is needed.
Will it fix a P0420 code?
It can if a slow or failed rear sensor is the cause. If the catalytic converter itself is failing, the code may return.
Do I need a special tool?
An oxygen sensor socket makes removal and installation much easier. The old sensor can seize from heat and rust.
