In most cases, replacing a single O2 sensor on a Honda CR-V runs about $150 to $350 installed, with OEM parts pushing the price higher. If both sensors (upstream and downstream) need replacement, budget roughly $300 to $700. Do-it-yourself parts can cut costs to roughly $20 to $120 per sensor, plus any tools you may need.
What affects the price
Several factors determine the final bill, including which sensor is being replaced (upstream versus downstream), the total number of sensors, whether you choose aftermarket or OEM parts, local labor rates, and any diagnostic fees charged by the shop. On most CR-V models with a four-cylinder engine, there are two sensors to consider: one upstream and one downstream. Always confirm the exact engine configuration and sensor location for your VIN.
Cost breakdown for a single O2 sensor
Prices below reflect common market ranges in the United States as of 2024–2026. The figures cover parts, labor, and typical diagnostic charges. Before listing, it’s important to understand these are approximate and can vary by region and shop.
- Parts cost for one O2 sensor:
- Aftermarket: about $20–$100
- OEM/dealer: about $80–$250
- Labor to install one sensor:
- Typical time: 0.5–1.5 hours
- Labor rate: about $80–$140 per hour
- Total labor: roughly $40–$210
- Diagnostic or shop supplies:
- Often $0–$120 depending on the shop and whether it’s bundled with the service
In practice, many shops quote a combined price for parts and labor of roughly $150–$350 for a single sensor, with OEM parts at the higher end. If a diagnostic fee applies, that will raise the upfront quote accordingly.
Cost for replacing both O2 sensors
When both upstream and downstream sensors are replaced on a Honda CR-V, parts and labor costs roughly double, though some efficiencies may apply if both are done in one visit. The ranges below reflect typical replacements on standard four-cylinder CR-Vs.
- Parts for two sensors:
- Aftermarket: about $40–$200 total
- OEM/dealer: about $160–$500 total
- Labor for two sensors:
- Typical time: 1–2.5 hours
- Labor rate: about $80–$140 per hour
- Total labor: roughly $80–$350
- Diagnostic or shop supplies:
- Usually bundled, or $0–$120 if charged separately
Overall, expect roughly $300–$700 installed for two sensors when using aftermarket parts, with OEM parts possibly pushing the range higher depending on regional labor rates and vehicle specifics.
Do-it-yourself considerations
Replacing an O2 sensor yourself can significantly cut parts costs, but it requires mechanical aptitude, basic hand tools, and an oxygen sensor socket. DIY parts typically range from about $20 to $100 per sensor for aftermarket options, with OEM parts following similar pricing patterns. You’ll also need to factor in tools and time, as well as ensuring proper handling to avoid contaminating the sensor tip. Always follow the sensor manufacturer’s instructions and torque specifications when installing a new sensor.
What you should know before you start
Key caveats include ensuring you’re replacing the correct sensor (upstream vs downstream), avoiding contamination of the sensor tip, and clearing trouble codes after replacement. Some vehicles require the engine to reach a specific operating temperature or for the ECU to relearn fuel trim after sensor replacement. If you’re unsure, consult a repair manual for your CR-V’s exact year and engine code, and consider a quick diagnostic scan to confirm that codes are cleared and the system is functioning properly after service.
Summary
Replacing an O2 sensor on a Honda CR-V generally costs between $150 and $350 for a single sensor and $300 to $700 for both sensors when performed by a shop. Parts costs vary widely by brand (aftermarket vs OEM), and labor costs depend on regional rates and how accessible the sensor is. Do-it-yourself replacements can reduce out-of-pocket costs to roughly $20–$100 per sensor for parts, plus any tools and your time. Always verify the exact sensor type and obtain a formal quote that itemizes parts, labor, and any diagnostic fees before authorizing service.
