On a 2007 Honda Accord, replacing a single oxygen sensor typically costs around $150 to $350, including parts and labor. If both sensors need replacement, expect roughly $300 to $700. Prices vary by engine type, sensor brand, and local labor rates, so it’s wise to obtain quotes from a few shops.
The exact price depends on whether you’re dealing with an upstream (pre-cat) sensor or a downstream (post-cat) sensor, as well as the engine configuration (4-cylinder vs. V6) and whether you choose an aftermarket or OEM sensor. Accessibility, diagnostic fees, and regional labor rates can also shift the total.
Cost breakdown by sensor type
Parts: OEM vs aftermarket
Sensor part costs vary by brand and whether you buy OEM from Honda or an aftermarket supplier. OEM sensors are typically more expensive but may come with longer warranties and guaranteed compatibility. In general, expect:
- Upstream (pre-cat) sensor: parts roughly $60–$200; labor about $40–$120; total per sensor roughly $100–$320.
- Downstream (post-cat) sensor: parts roughly $60–$180; labor about $40–$130; total per sensor roughly $100–$310.
Note: Some shops quote higher if the sensor is challenging to reach or if dual replacement is required during the same visit.
Labor considerations
Labor time varies with engine layout and access. Most 2007 Accords require about 0.5 to 1.0 hour to replace a single O2 sensor. Regional shop rates commonly range from $75 to $150 per hour, affecting the final bill.
- Single-sensor replacement: typically 0.5–1.0 hours.
- Two-sensor replacement (common on 4-cylinder): typically 1.0–2.0 hours total.
Final price hinges on the actual time counted by the shop and whether any sensor is difficult to reach or has seized.
Two-sensor configurations and engine variations
Most four-cylinder 2007 Accord models use two O2 sensors (upstream and downstream). Some V6 variants have four sensors (two banks). Because of this, the cost scales with the number of sensors being replaced.
- 4-cylinder with 2 sensors: rough total for parts and labor is typically $200–$700, depending on OEM vs aftermarket and local rates.
- V6 with 4 sensors: rough total for parts and labor is typically $600–$1,400, depending on brands and labor rates.
Always confirm the exact sensor count for your specific engine and obtain a written estimate before authorizing work.
Other price factors to consider
Beyond the sensor count, several factors influence the final bill:
- Diagnostic fees: Some shops charge a diagnostic fee if you don’t proceed with the repair, though this may be waived if you authorize the replacement.
- Brand and warranty: OEM sensors carry higher upfront costs but may include longer warranties.
- Location and shop type: Dealer service departments tend to be more expensive than independent shops, and urban areas often have higher labor rates.
To avoid surprises, ask for a detailed, written estimate that itemizes parts, labor, and any diagnostic charges. Also, request the labor hours and the exact sensor part numbers.
Summary
For a typical 2007 Honda Accord with two sensors on a 4-cylinder engine, expect roughly $200–$700 for parts and labor combined. If the vehicle uses four sensors (common on some V6 models), the range is approximately $600–$1,400. Prices vary with OEM vs aftermarket parts, engine configuration, accessibility, and local labor rates. Always obtain multiple quotes, request itemized estimates, and confirm whether diagnostic fees apply before proceeding.
What are the symptoms of a bad O2 sensor on a Honda Accord?
A well-working O2 sensor can be an important component of a consistent running car. Still, a bad O2 sensor can probably lead to bad smells from your car, poor gasoline efficiency, and a below-level running engine.
Can I still drive with a bad O2 sensor?
If My Oxygen Sensor Fails, Can I Still Drive My Vehicle? We recommend not driving with a bad O2 sensor as the powertrain isn't running on the correct fuel mixture.
How much is a oxygen sensor for a 2007 Honda Accord?
The average price for a 2007 Honda Accord Oxygen Sensor at Advance Auto Parts is around $86.01, with a range that starts at $64.99 and goes up to $108.99.
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.
