Oxygen sensor replacement cost
for a Honda CR-V

Replacing a faulty oxygen sensor on a Honda CR-V involves locating and swapping out the sensor, typically on the exhaust manifold or downstream in the exhaust system. The cost is driven by the price of the OEM vs. aftermarket sensor and the labour time, which varies if the sensor is easily accessible or seized.

Can you do it yourself?

Possible with skill — requires basic tools, O2 sensor socket, and ability to safely access undercarriage/exhaust.

Tips before you pay

Use an O2 sensor socket and penetrating oil if the sensor is old/rusty to avoid breaking it.
Diagnose with an OBD2 scanner first to confirm which sensor (Bank 1 Sensor 1, etc.) is faulty.
Consider using a Honda OEM or high-quality aftermarket sensor for longevity and proper fuel trim readings.
