DENSO 234-9051 air / fuel ratio sensor for the 2005-2007 Toyota 4Runner V6 4.0L, the 2005-2009 4Runner V8 4.7L and other vehicles reads the air-fuel ratio in the exhaust and reports it to the engine computer. This wide-band sensor mounts upstream in the exhaust.
- Laser-welded stainless housing resists corrosion
- PTFE filter blocks contaminants under harsh engine conditions
- Dual-layer protection shields the ceramic element for fast, reliable response times
- Heated, 4-wire wide-band design with a male connector
- 8.66 in wiring harness
Quick facts
- Part: DENSO 234-9051 air / fuel ratio sensor
- Fits: 2005-2007 Toyota 4Runner V6 4.0L, the 2005-2009 4Runner V8 4.7L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A check engine light, rough running or poor fuel economy can be signs of a worn sensor. An exhaust leak, damaged wiring or an engine misfire can be behind the same signs, so find the cause before buying.
Fits
The 2005-2006 Toyota Tacoma V6 4.0L, the 2005-2007 Toyota Tundra V8 4.7L, the 2006-2007 Tundra V6 4.0L and the 2007 Tundra V8 5.7L take this sensor, and so do many other Toyota and Lexus models. Open the "Vehicles it fits" section to check your exact model and engine. This listing is one sensor; the 2005-2006 Tacoma V6 4.0L takes two, and other applications take one or two.

Frequently Asked Questions
Is this the right Toyota Tacoma air fuel ratio sensor for a 2005-2006 Tacoma V6 4.0L?
Yes. DENSO 234-9051 fits the 2005-2006 Toyota Tacoma V6 4.0L, which takes two sensors.
Does this Toyota 4Runner air fuel ratio sensor fit the 2005-2009 4Runner V8 4.7L?
Yes. DENSO 234-9051 fits the 2005-2009 Toyota 4Runner V8 4.7L, which takes two sensors. The 2005-2007 4Runner V6 4.0L also takes two.
Is the DENSO 234-9051 a wide-band sensor, and how many wires does it have?
Yes. It is a heated wide-band sensor with four wires and a male connector. The wiring harness is 8.66 in long.
What can a failing air / fuel ratio sensor look like?
A check engine light, rough running or a drop in fuel economy can be signs. A shop can read the stored codes to see whether the sensor is involved.
Is the housing on this DENSO air / fuel ratio sensor stainless?
Yes. The housing is laser-welded stainless that resists corrosion, and a PTFE filter blocks contaminants.
