How much is a oxygen sensor for a Acura?
Oxygen sensors for Acura typically cost between $25 and $250 per sensor, depending on whether you choose an aftermarket or OEM part, and whether it's upstream or downstream. Labor is extra.
Oxygen sensors monitor exhaust oxygen levels to help the engine control module adjust fuel mix and emissions. Prices vary by sensor type, model year, and where you buy. This article explains typical price ranges, what drives the cost, and how to shop for the right sensor for your Acura.
What affects the price
Several factors influence cost: OEM versus aftermarket parts, whether you need the upstream (sensor 1) or downstream (sensor 2) sensor, direct-fit versus universal designs, the Acura model and engine, and where you purchase the part. Regional pricing and current promotions can also shift prices.
Typical price ranges by sensor type
Prices vary by function and brand. The ranges below reflect common market prices for North American buyers as of 2024–2025 and may vary by region and retailer.
- Upstream (sensor 1, pre-cat)
- Direct-fit aftermarket: $40–$120
- OEM Acura genuine: $120–$210
- Downstream (sensor 2, post-cat)
- Direct-fit aftermarket: $40–$110
- OEM Acura genuine: $130–$210
- Premium aftermarket sensors (e.g., Denso, NTK, Bosch)
- Direct-fit: typically $60–$180
- Used or refurbished sensors
- Approximately $20–$75
Note that prices fluctuate with promotions, availability, and vehicle specifics. Always verify compatibility with your exact Acura model and year before purchasing.
How to identify the right sensor for your Acura
Before buying, confirm whether you need the upstream or downstream sensor, and obtain the exact OEM part number or a cross-reference using your car’s VIN. This ensures the part you order fits and functions correctly.
Finding the exact part number
Check the sensor body for an OE number, consult your owner’s manual, or use a VIN-based catalog from a reputable retailer or dealer. If you’re unsure, a dealer or independent shop can confirm the correct sensor and bank specification (e.g., bank 1 sensor 1 vs bank 1 sensor 2).
Where to buy
Options include Acura dealers for genuine OEM sensors, nationwide auto parts chains, and online retailers. Compare price, warranty, and return policies. OEM parts tend to be pricier but may simplify warranty claims; aftermarket sensors can offer lower prices with solid warranties.
Labor and installation considerations
Installation time is typically 0.5 to 1 hour per sensor for a standard vehicle, but it can take longer on models with tightly restricted access or corroded threads. Labor costs vary by region and shop policy.
Tips to reduce cost
Get multiple quotes, consider replacing sensors as a pair if both need replacement, and ask if the price includes labor and any mounting hardware. Some shops offer emissions-related service packages that include sensor replacement.
Summary
In short, Acura owners typically see O2 sensor prices ranging from about $40 to $120 for direct-fit aftermarket upstream or downstream sensors, $120 to $210 for OEM units, and $60 to $180 for premium aftermarket variants. Used sensors can be as cheap as $20, while labor adds roughly $80 to $150 per sensor depending on location and complexity. Always verify your exact model year and engine code to select the correct sensor and safeguard against compatibility issues.
