NTK 24333 air / fuel ratio sensor for the 2019-2024 Mercedes-Benz G550 V8 4.0L and other vehicles reads how rich or lean the engine is running and reports it to the ECU. This NTK air fuel ratio sensor lets the ECU adjust the air-fuel mixture continuously toward stoichiometric.
- 5-wire wideband design with a linear output signal, where a switching sensor only reports rich or lean
- Heated sensor
- 3-stage contaminant-resistant plasma jet and deposit trap overcoat that protects against element poisoning
- Dual-coated platinum interface and a thinner ceramic element for quick light-off and response
- Vibration and thermal shock testing during development, plus testing during manufacturing
Quick facts
- Part: NTK 24333 air / fuel ratio sensor
- Fits: 2019-2024 Mercedes-Benz G550 V8 4.0L and other vehicles
- Position: Upstream, downstream, upstream left, upstream right
- Condition: New
A lit check engine light, rougher running or a drop in fuel economy can mean the sensor is wearing out. An exhaust leak, a vacuum leak or a tired catalytic converter can be behind those signs too, so find the cause before you buy. If the sensor is at fault, this one replaces it.
Fits
The 2019-2024 Mercedes-Benz G550 V8 4.0L, the 2019-2024 Mercedes-Benz G63 AMG V8 4.0L and the 2022-2024 Mercedes-Benz G63 4X4 Squared AMG V8 4.0L are covered, along with many other BMW and Mercedes-Benz models. If your car is not named here, run its year, model and engine through the "Vehicles it fits" section. This listing is a single sensor, and the fitment lists a quantity of one for each application.

Frequently Asked Questions
Does the NTK 24333 fit the 2019-2024 Mercedes-Benz G63 AMG V8 4.0L?
Yes. NTK 24333 is listed for the 2019-2024 Mercedes-Benz G63 AMG V8 4.0L, and that application takes one sensor.
What is the hex size on the NTK 24333 sensor?
The NTK 24333 has a 7/8" (22 mm) hex. It is a heated, 5-wire wideband sensor.
Does this sensor send a switching or a linear signal?
Linear. This wideband sensor lets the ECU see exactly how rich or lean the engine is running, where a conventional switching sensor only reports rich or lean.
Has this wideband air / fuel ratio sensor been tested for vibration and thermal shock?
Yes. Development includes vibration and thermal shock testing, and the sensor is tested again during manufacturing.
Which signs can point to a worn wideband air / fuel ratio sensor?
A check engine light, hesitation or a failed emissions test can be signs of a worn sensor. A shop can read the stored codes to see where the problem is.
