DENSO Auto Parts Air / Fuel Ratio Sensor P/N:234-9074
DENSO Auto Parts 234-9075 air / fuel ratio sensor for the 2005-2009 Land Rover LR3 V6 4.0L or V8 4.4L and other vehicles measures the air-fuel ratio in the exhaust and sends the reading to the engine computer. The computer uses that reading to adjust fuel delivery.
A check engine light, poor fuel economy or a rough idle can mean the sensor is wearing out. A vacuum leak is another common source of these symptoms, so these signs alone do not prove the sensor is the problem.
This direct-fit sensor fits the 2005-2009 Land Rover LR3 V6 4.0L or V8 4.4L and the 2006-2009 Land Rover Range Rover Sport V8 4.2L or 4.4L. Two go on each vehicle, and this listing is one upstream sensor.
