Repair costs / Oxygen sensor replacement

Oxygen sensor replacement cost: what's fair?

Typical all-in range (parts + labor)

$68–$359

Parts about $30–$95. Labor about $38–$264 (0.4–1.2 hrs at typical rates).

A oxygen sensor replacement is usually prompted by a check-engine light or poor fuel economy. The single biggest driver of an unfair price isn't the labor — it's parts markup. Shops commonly charge well above retail for the part itself, and that's the easiest thing for you to verify and push back on.
