Oxygen sensor replacement cost
for a Honda Civic

Replacing a faulty oxygen (O2) sensor on a Honda Civic involves locating and removing the old sensor from the exhaust manifold or pipe, then installing a new one to restore proper fuel mixture readings. The cost is primarily driven by the price of the sensor itself and whether one or both upstream sensors need replacement. Labor costs are generally moderate as access is often straightforward on this model.

Cost breakdown

Parts: ~$70-$200 / Labour: ~$110-$200

What affects the price

Sensor Location: Upstream (pre-catalytic converter) sensors are more expensive than downstream ones.
Sensor Brand: Genuine Honda/OEM parts cost significantly more than aftermarket equivalents.
Model Year & Engine: V6 or turbocharged models may have more complex sensor configurations or harder access.

Can you do it yourself?

Yes (brief how) — With basic tools, a sensor socket, and safety precautions for working under the car, a single sensor replacement is often feasible for a DIYer.

Tips before you pay

Always use an anti-seize compound on the new sensor's threads, but avoid getting it on the sensor tip.
Diagnose which specific sensor (Bank 1 Sensor 1, etc.) is faulty via an OBD2 scanner to avoid unnecessary replacements.
On older Civics, be prepared for a seized sensor; applying penetrating oil and using careful heat can help avoid damaging the exhaust component.
