DENSO 234-5134 air / fuel ratio sensor for the 2004-2006 BMW X5 V8 4.4L or 4.8L and other vehicles measures the oxygen content of the exhaust so the engine computer can adjust fueling.
- 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
- Wide-band, heated sensor with five wires
Quick facts
- Part: DENSO 234-5134 air / fuel ratio sensor
- Fits: 2004-2006 BMW X5 V8 4.4L or 4.8L and other vehicles
- Position: Upstream, upstream left, upstream right
- Condition: New
A check engine light, rough running or poorer fuel economy can mean the sensor is worn, though they have other causes too. Before you replace this sensor, rule out damaged wiring or an exhaust leak near it, and let a shop scan for codes.
Fits
The 2004-2006 BMW X5 V8 4.4L or 4.8L (one sensor per vehicle), the 2003-2006 BMW 325Ci 6-cylinder 2.5L (two) and the 2003-2006 Porsche Cayenne V8 4.5L (two) all take this direct-fit replacement, as do other vehicles. This listing is one sensor. If your car is not named here, look it up in the "Vehicles it fits" section.
