Part number 24094 is built for buyers searching for a direct fit oxygen sensor for Honda Pilot downstream front replacement, a Honda Ridgeline B2S2 oxygen sensor replacement, or an Acura MDX and Acura TLX downstream front oxygen sensor. The NTK 24094 is also a relevant search match for drivers replacing a heated 4-wire oxygen sensor with threaded mounting and OE-style dimensions.

What This Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Fault codes tied to downstream front sensor readings
• Incorrect air-fuel feedback from a worn sensor
• Emissions inspection failures caused by sensor degradation
• Rough or inconsistent engine management data from aging sensor components

Installation Notes and Tips

Confirm the downstream front location and connector match before installation. Verify thread diameter, wire count, and harness length against the original sensor to ensure proper routing and fit. For best results, inspect the exhaust threads and wiring path before installing the new sensor.

Quality Assurance

NTK manufactures oxygen sensors with controlled ceramic technology and extensive production testing to meet or exceed OE specifications. The brand supplies original equipment oxygen sensors globally, and this direct fit design reflects that OE-focused engineering approach.
