NTK 24783 air / fuel ratio sensor for the 2013-2014 Nissan Altima V6 3.5L, the 2013-2018 Altima 4-cylinder 2.5L and other vehicles reports to the ECU how rich or lean the engine is running. This NTK air fuel ratio sensor is a wideband type, so its output signal is linear instead of only switching rich or lean.
A worn air / fuel ratio sensor can show up as a check engine light, rough running or lower fuel economy. A leak in the exhaust, a damaged wiring connector or another sensor can be behind those symptoms too, so track down the cause before you buy.
The vehicles it fits include the 2013-2014 Nissan Altima V6 3.5L, the 2013-2018 Altima 4-cylinder 2.5L, the 2013-2019 Nissan Sentra 4-cylinder 1.8L and the 2013-2014 Nissan Frontier V6 4.0L, along with a wide range of other Nissan, Infiniti and Chevrolet models. If your car is not named here, look up its year and engine in the "Vehicles it fits" section.
Fit and size
Build and materials
One air / fuel ratio sensor; each application in the fitment takes one.
This part cross-references / interchanges with the following part numbers:
Is this the right air fuel ratio sensor for the 2013-2019 Nissan Sentra 4-cylinder 1.8L?
Yes. NTK 24783 fits the 2013-2019 Nissan Sentra 4-cylinder 1.8L, and the fitment lists a quantity of one.
Is this air fuel ratio sensor right for a 2016 Nissan Altima in the 2013-2018 Altima 4-cylinder 2.5L range?
Yes. NTK 24783 fits the 2013-2018 Nissan Altima 4-cylinder 2.5L, which includes 2016. For other cars, use the "Vehicles it fits" section.
Is the NTK 24783 sensor heated, and what hex does it use?
Yes. NTK 24783 is a heated 4-wire A/F sensor with a 7/8 in (22 mm) hex.
Can a worn wideband air / fuel ratio sensor affect fuel economy?
Yes, it can. The ECU relies on this sensor's linear signal to adjust the air-fuel mixture, so a worn one may bring rough running, a check engine light or lower mileage. A shop can test it.
What protects the ceramic element of this wideband sensor from contamination?
The element has a 3-stage plasma jet and deposit trap overcoat, which guards the ceramic against contaminants that would poison it.
