Average Cost
$200 to $550+
Typical total depends on sensor location, labor rate, and whether diagnosis confirms a failed sensor instead of a wiring or catalyst issue.

Oxygen Sensor Replacement Cost
Oxygen sensor replacement cost usually depends on whether the sensor is upstream or downstream, how accessible the exhaust is, and whether corrosion makes removal harder than expected. This page gives a clean baseline so you can understand the job before moving into the estimator.
Labor Time
1.0 to 2.5 hours
Many sensors are fairly quick to replace, but rusted threads, heat shielding, and hard-to-reach exhaust routing can add time.
Parts Cost
$80 to $300+
Price changes based on universal versus direct-fit sensors, sensor brand, and whether the vehicle uses multiple sensors.
Common Symptoms
- Check engine light with oxygen-sensor-related codes
- Poor fuel economy
- Rough running or hesitation in some cases
- Failed emissions or readiness monitor issues
- Slow sensor response during scan tool testing
What Affects Cost
- Upstream versus downstream sensor location
- Sensor access and exhaust corrosion level
- Need for diagnosis before replacement
- Direct-fit versus universal sensor choice
- Vehicle sensor count and emissions system layout
