Oxygen sensor replacement cost
for a Honda Accord

Replacing the oxygen sensor(s) on a Honda Accord involves locating the faulty sensor(s), disconnecting its electrical connector, and unscrewing it from the exhaust manifold or pipe. The cost is primarily driven by the number of sensors replaced (most Accords have at least two) and the sensor's location, which affects labour time.

What affects the price

Number of sensors replaced (common to replace just the upstream sensor)
Sensor location (upstream/manifold often easier than downstream/catalytic converter)
Use of OEM vs. aftermarket or universal sensor parts

Can you do it yourself?

Possible with skill — requires an OBD2 scanner to diagnose the faulty sensor, proper socket tools, and caution working near the hot exhaust.

Tips before you pay

Use an OBD2 code reader to identify which specific sensor (Bank 1, Sensor 1, etc.) is faulty before starting.
Apply penetrating oil to the sensor threads beforehand, as they can be severely rusted in place.
Ensure the engine is completely cool to avoid burns and to get an accurate torque reading when installing the new sensor.
