DENSO Auto Parts Air / Fuel Ratio Sensor P/N:234-9098
DENSO Auto Parts 234-9104 air / fuel ratio sensor for the 2012-2017 Nissan NV2500 V8 5.6L and other vehicles reads the air-fuel ratio in the exhaust and reports it to the engine computer. The sensor is made and tested to strict OE standards.
A worn sensor can show up as a check engine light, poor fuel economy or a rough idle, though each of those signs can have other causes. With the engine off and cool, look over the wiring and connector for cracked or melted insulation before you replace the sensor. If a failed sensor is the cause, this one replaces it.
It is a direct-fit replacement for the 2012-2017 Nissan NV2500 V8 5.6L, the 2012-2017 Nissan NV3500 V8 5.6L and the 2011-2012 Infiniti G25 V6 2.5L. This listing is one sensor, and every vehicle named here takes two.
