3 – When does the Oxygen Sensor need to be replaced ?
The lifespan of a Oxygen Sensor is 160,000 km on average, as long as it is not shortened by engine malfunction.
Unburned oil due to engine misfire may contaminate the probe irreversibly. Exhaust leaks also damage the Oxygen Sensor, leading to an intake of air which can cause a dangerous increase in temperature.
To ensure the maximum lifespan of the Oxygen Sensor, it is necessary to perform strict engine maintenance (spark plugs, air filter, et al.).
Several signs that your Oxygen Sensor needs to be replaced:
- If the engine check light turns on while the vehicle is being driven.
- The engine stutters and suffers from a lack of acceleration power.
Diagnosis of the Oxygen Sensor :
A defective oxygen sensor is detected only by a special diagnostic tool used by trained professionals. It is therefore necessary to have this service administered at a professional garage.
