NTK 24308 air / fuel ratio sensor for the 2008-2010 Audi A5 Quattro V6 3.2L and other vehicles sends the ECU a linear signal. It lets the ECU see exactly how rich or lean the engine is running and adjust the air-fuel mixture continuously.
- Advanced ceramic sensor element with a 3-stage contaminant-resistant plasma jet and deposit trap overcoat against element poisoning
- Dual-coated platinum interface and thinner ceramic element for quick light-off and response times
- Vibration and thermal shock testing during development, plus testing during manufacturing
- Water-resistant connector and harness accessory hardware for easier installation
Quick facts
- Part: NTK 24308 air / fuel ratio sensor
- Fits: 2008-2010 Audi A5 Quattro V6 3.2L and other vehicles
A check engine light, a drop in fuel economy or rough running can be signs of a failing air / fuel ratio sensor. Wiring faults can look alike, so with the engine off and cool, look over the harness and connector for cracks or burnt insulation before replacing the sensor. A shop can test the signal itself.
