The typical total for replacing a single oxygen sensor on a 2005 Honda Accord is about $150 to $350, depending on sensor type and labor rates. Costs can be lower if you buy the part yourself and have a shop install it, or higher if multiple sensors are involved or labor is expensive in your area.
What drives the price
Prices vary by sensor position (upstream vs downstream) and whether you choose aftermarket parts or Honda OEM sensors. The 2005 Accord’s engine options influence how many sensors you might need to replace, which affects the overall cost.
- Pre-cat (upstream) oxygen sensor: aftermarket typically about $25–$120; Honda OEM part often in the $90–$180 range.
- Post-cat (downstream) oxygen sensor: aftermarket typically about $25–$150; Honda OEM part often in the $110–$250 range.
- Vehicle configuration matters: a 2005 Accord with the four-sensor setup (varies by engine) may require replacement of more than one sensor, increasing parts costs accordingly.
In practice, most drivers replace a single failing sensor, but costs rise if more sensors are replaced or if the sensor is hard to access.
Labor costs and installation considerations
Labor costs depend on how long the replacement takes and the local hourly rate. Here are common factors that shape the labor portion of the bill.
- Labor time: replacing a single O2 sensor typically takes about 0.5 to 1.5 hours, depending on sensor location and access. Hard-to-reach sensors can take longer.
- Labor rate: common shop rates range from $75 to $125 per hour; in expensive metropolitan areas, rates can be $150 to $200 per hour.
- Special cases: seized sensors, corroded wiring, or exhaust system work required to reach the sensor can add time and cost.
Overall, a straightforward single-sensor replacement tends to stay toward the lower end of the range, while replacing multiple sensors or dealing with access issues pushes the total higher.
Summary
For a 2005 Honda Accord, replacing one oxygen sensor typically costs about $150 to $350 total, including parts and labor. Parts price varies by sensor position and whether you use aftermarket or OEM components, while labor depends on shop rates and how long the job takes. If multiple sensors are involved or if access is difficult, expect higher costs. Always obtain an itemized estimate that separates parts and labor, and consider whether replacing sensors in pairs is advisable for longevity and performance.
