How many miles does an oxygen sensor last?
In addition to high heat, the sensor can be affected by other things, including contaminants in the exhaust, excessive amounts of unburned fuel in the system and more. Generally speaking, your oxygen sensor should last somewhere between 50,000 and 60,000 miles.
What’s the warranty period for an oxygen sensor?
The current Federal OBD II warranty period for an oxygen sensor is two years or 24,000 miles, whichever comes first, but with proper care and the right fuel diet, the oxygen sensor should be a maintenance-free emissions system component.
What happens when an O2 sensor goes bad?
Oxygen sensors play a vital role in both engine management and emissions control. When an O2 (oxygen) sensor go bad, it’ll cause your Hyundai Elantra ‘s engine to run less efficiently. Your Elantra can exhibit symptoms when the Oxygen sensor has gone bad.
How much does it cost to replace an oxygen sensor?
A new oxygen sensor can cost from less than $100 on some models to $300 or more on others, but that doesn’t include labor, which can vary widely by vehicle because of where the sensors are located. As a result, the full cost of oxygen sensor replacement may vary greatly depending on the type of vehicle you drive.
What is the life expectancy of an oxygen sensor?
The life expectancy of an oxygen sensor is typically 30,000 to 50,000 miles . Even under normal operating conditions, oxygen sensors must endure a constant barrage of harm – ful exhaust gases, extreme heat and high velocity particulates. When these variables of heat and contamination exceed normal limits, longevity may be reduced. Sometimes oxygen sensors can become contaminated by coolant, oil or silicone partic – ulates.
Why to replace O2 sensor?
Any O2 sensor that is defective obviously needs to be replaced. But there may also be benefits to replacing the O2 sensor periodically for preventive maintenance. Replacing an aging O2 sensor that has become sluggish can restore peak fuel efficiency, minimize exhaust emissions and prolong the life of the converter.
When to replace O2 sensor?
Car manufacturers recommend replacing the O 2 sensor about every five years (one- and two-wire sensors) or 10 years (three- and four-wire sensors). However, silicon or carbon soot may cover an oxygen sensor due to a car repair or engine performance problems.
How often to change O2 sensor?
Heated three and four-wire O2 sensors on mid-1980s through mid-1990s applications should be changed every 60,000 miles. And on 1996 and newer OBD II-equipped vehicles, the recommended replacement interval is 100,000 miles. A good oxygen sensor is essential for good fuel economy, emissions and performance.
