O2 Sensor Replacement Cost
O2 Sensor Replacement typically costs $105–$478 across economy, mainstream and premium vehicles, including reference parts and labor. An oxygen-sensor-related code can arise from wiring or mixture problems.
| Vehicle type | Parts | Labor hours | Total |
|---|---|---|---|
| economy | $50–$140 | 0.5–1.1 | $105–$344 |
| mainstream | $80–$170 | 0.7–1.3 | $157–$411 |
| premium | $110–$200 | 0.9–1.5 | $209–$478 |
Labor uses the configured national band of $110–$185/hour. Vehicle windows narrow both reference parts and hours; pickup, full-size SUV and van access can require more labor. This table is a reference estimate, not a complete quote analysis.

What’s included
- Correct upstream or downstream sensor, wiring inspection and fault verification
What’s often done at the same time
No other published repair is paired with this reference. Ask whether the estimate includes related access work and avoid adding unrelated services without supporting findings.
Signs you need it
- Sensor response or heater failure supported by testing
How shops can pad this quote
