NGK 24331 NTK Wideband Air/Fuel Ratio Oxygen Sensor, 5-Wire, M18x1.5

The NGK (NTK) 24331 is an OE-type wideband oxygen sensor, also called an air/fuel ratio (AFR or A/F) sensor. It measures the exhaust gas mixture and sends the ECU a linear signal. The ECU uses that signal to adjust the air/fuel mixture continuously. This helps keep combustion efficient, fuel economy good and emissions low.

Key Features:

• Wideband planar sensing element and integrated heater for fast light-off and precise air/fuel ratio measurement (approximately 10:1 to 28:1)
• Dual-coated platinum element for longevity and quick response time
• 3-stage contaminant-resistant overcoat protects the element from poisoning
• Heated, 5-wire design with an OE-type connector and wiring harness for direct-fit installation
• Water-resistant OE-specified connector
