A-Premium Downstream O2 Oxygen Sensor — Heated 4-Blade Direct-Fit for Honda & Acura (Single)

The A-Premium Downstream O2 Oxygen Sensor is a direct-fit, heated replacement sensor for many Honda and Acura models, supplying accurate exhaust readings with a 4-blade terminal and threaded mount for reliable installation.

This downstream (rear) oxygen sensor from A-Premium is designed to match OEM fitment and function across a broad range of Honda and Acura vehicles. It uses a heated sensing element and a 4-blade male connector, ships in a protective box, and is intended to restore correct downstream O2 feedback for emission control and engine management systems. Reference numbers include 36542-R70-A01, 36542R70A01, 250-24785, and 2344461.

Which vehicles does this A-Premium downstream O2 sensor fit?

Fitment covers many model years and engine variations across Honda and Acura. Check your vehicle’s year, engine size and whether the required location is downstream (rear) or downstream front to ensure compatibility before purchase.

• Acura MDX, RL/ RLX, RDX, TL/TLX, ZDX models listed for 2007–2023 depending on engine size.
• Honda Accord, Crosstour, Odyssey, Pilot, Ridgeline, Passport across 2008–2023 model years in specific V6 and L4 engines.
• Multiple fitment tables provided: downstream rear, downstream front or rear, and downstream-only variations—refer to exact vehicle list when ordering.

How is the sensor built and what are the key specifications?

This oxygen sensor is a heated type with a threaded mounting for a secure, OEM-style installation. It uses a 4-blade (4-terminal) male connector and is shipped as a single sensor in a box for easy replacement.

• Sensor Type: Heated oxygen sensor for faster warm-up and stable readings.
• Terminal Quantity: 4-blade male connector for correct electrical matching.
• Mounting Type: Threaded body to screw into the existing exhaust bung.
• Package Quantity: 1x oxygen sensor, packaged in a protective box.

Will this sensor restore emissions performance and check-engine issues?

Replacing a worn or faulty downstream O2 sensor with a compatible, properly installed unit often helps the vehicle’s emissions monitoring return to normal and can eliminate related trouble codes. However, results depend on correct fitment, wiring integrity, and the overall health of the exhaust and catalytic converter.

• Direct-fit design minimizes wiring splicing or adapter use when matched to the correct application.
• Heated element helps the sensor reach operating temperature sooner for quicker diagnostics.
• Use a diagnostic scan after replacement to confirm fault-code resolution and monitor sensor readings.

Who is this for: The A-Premium downstream O2 sensor is intended for DIYers, professional technicians, and fleet maintenance teams who need a cost-effective, direct-replacement sensor for supported Honda and Acura models. Buy this part if your vehicle’s downstream O2 sensor is failing, showing related trouble codes, or when an OEM-number-compatible replacement is required. Always verify the exact model year, engine code, and sensor location (downstream, downstream front or rear) against the fitment lists before ordering to ensure proper compatibility.
