Replacing a single oxygen sensor on a Honda Fit typically costs about 150 to 300 USD, including parts and labor. If both sensors are replaced or OEM parts are used, the total can rise to roughly 300–600 USD or more, depending on where you shop and the exact part choices.
Cost components and what drives the price
The price you pay for an oxygen sensor replacement is driven mainly by parts cost (OEM vs aftermarket) and labor charges. The Honda Fit usually has two sensors (upstream and downstream), and access complexity can affect how long the job takes.
Parts cost by sensor type
Costs for individual oxygen sensors vary by sensor type and whether you select aftermarket parts or OEM parts. The ranges below reflect common options for a Honda Fit.
- Upstream (pre-cat) oxygen sensor:
- Aftermarket parts: about 40–120 USD
- OEM/dealer parts: about 100–300 USD
- Downstream (post-cat) oxygen sensor:
- Aftermarket parts: about 40–120 USD
- OEM/dealer parts: about 130–320 USD
Prices can vary by brand and where you buy them, and some models may use two upstream sensors or have slightly different configurations depending on year and engine variant.
Labor costs
Labor costs depend on local shop rates and how easily the sensor can be accessed. Here are typical figures you might see.
- Estimated time to replace a single O2 sensor: 0.6–1.5 hours
- Typical labor rate: 80–150 USD per hour
These figures translate to a rough labor cost per sensor of about 50–225 USD, depending on how long the job takes and the local hourly rate.
Total cost ranges
Combining parts and labor, here are expected total ranges for Honda Fit oxygen sensor replacements. Note that actual prices can vary by region, shop, and part choice.
- Single sensor replacement (parts + labor):
- Aftermarket parts: roughly 90–345 USD
- OEM parts: roughly 150–525 USD
- Two sensors replaced at once (parts + labor):
- Aftermarket parts: roughly 176–690 USD
- OEM parts: roughly 296–1050 USD
Some shops may charge diagnostic fees, disposal fees for old parts, or extra labor if the sensor is difficult to reach or corroded in place.
Tips to save money
To keep costs down, consider the following strategies when planning an oxygen sensor replacement for your Honda Fit:
- Get quotes from multiple reputable shops and ask for itemized estimates (parts vs labor).
- Consider aftermarket sensors from trusted brands, which are typically cheaper than OEM parts.
- Ask the technician to confirm whether only one sensor is truly necessary or if both should be replaced at once.
- Check for any existing code-related issues that might require additional repair beyond the sensor itself.
Being informed about parts options and labor expectations can help you avoid surprises at the counter.
Summary
For a Honda Fit, replacing one oxygen sensor generally runs around 90–345 USD with aftermarket parts or 150–525 USD with OEM parts, including labor. Replacing both sensors at once can cost about 176–690 USD (aftermarket) or 296–1050 USD (OEM). Prices vary by year, engine variant, region, and shop, so it pays to shop around and obtain written quotes before proceeding.

Is it worth fixing an O2 sensor?
If your oxygen sensor isn't working, your engine burns more fuel than needed. That means you're wasting money at the pump. It can also cause damage to other parts like the catalytic converter, which is a much more expensive repair.
