Detailed Description
NTK 24540 is part of the Direct Fit Oxygen Sensor line, developed for straightforward replacement in emission control systems. As a downstream oxygen sensor for 1996-1998 Acura TL models, it is built to match the original sensor’s mounting style and electrical configuration. The 4-wire heated design and threaded 18 mm sensor body support accurate exhaust monitoring in the intended application. NTK 24540 is also referenced by part number 24540 for ordering and catalog matching.
NTK’s oxygen sensor program is backed by the brand’s OE-focused manufacturing approach and extensive testing during production. That background matters when selecting an Acura TL oxygen sensor replacement or a direct fit downstream oxygen sensor for import applications. The NTK 24540 part number is commonly used in catalog searches alongside the vehicle fitment and sensor type.
What It Is Used For
- Replacing a failed downstream oxygen sensor
- Restoring exhaust feedback for emission system operation
- Addressing sensor-related fault codes tied to oxygen sensing
- Correcting drivability issues caused by inaccurate exhaust readings
- Servicing a specific-fit Acura TL emission control application
Installation Notes and Tips
Verify the downstream location, connector routing, and thread size before installation. Match the 4-wire heated sensor configuration and harness length to the original unit to ensure proper fitment. Use the vehicle’s service information for torque and connector handling procedures.
Quality Assurance
NTK states that its oxygen sensors are extensively tested during manufacturing and built to meet or exceed OE specifications. The brand is part of the NGK family and is recognized as a major original equipment oxygen sensor supplier.
