FixHonda Accord — Oxygen Sensor Replacement Cost
What owners actually paid
The shaded middle is where half of all these repairs landed: $231 – $429. A quote inside that band is normal. Cheaper or pricier isn't automatically wrong — but it's worth asking why.
Real repair reports
These reports are a recent sample of real, paid Honda Accord oxygen sensor replacement visits — quoted the way the owner and the technician actually said it.
Car owners said
“Replace failing downstream oxygen sensor”
“Diagnose mil indicator lamp (check engine)”
“Cel on, p0159 ho2s sensor 2 slow response”
“Customer states- check engine light is on”
“Customer states that check engine light is on. check and advise”
What this repair is
Oxygen sensors measure the exhaust so the engine computer can tune the fuel mix. A lazy or dead sensor is one of the most common check-engine-light causes and quietly costs fuel economy. Cars have two to four of them; the price depends on which one and how rusted its threads are.
Is your quote fair?
If your quote lands between $231 and $429, it's inside the range where half of all real Honda Accord repairs of this kind land — and the typical job takes about 1.5 hours of labor. Quotes well below aren't automatically good news (economy parts, or related work skipped) and quotes above aren't automatically gouging (trim variants, premium parts, seized hardware) — but both ends deserve questions.
