The precise mix of fuel and air determines how well your car performs. When that balance is off, your engine may struggle, burn more fuel, and produce excess emissions. What helps maintain that balance? A small but important emission system component called the oxygen sensor.
At Frank’s Auto Service and Repair in Walnut Creek we provide comprehensive automotive emission system service and repairs, including, diagnosing and replacing faulty oxygen sensors. Doing so restores your vehicle’s performance, fuel efficiency, and keeps excessive pollution form our atmosphere. Your car's computer receives data from the oxygen sensors that measure the amount of oxygen in your exhaust gasses. This allows the computer to correct the air-fuel ratio for lower emissions.
Most modern autos include at least two oxygen sensors, one before and one after the catalytic converter, some vehicles may have as many as four. The average lifespan of these sensors is 60,000-90,000 miles. Over time, they will wear out due to high heat, carbon buildup, or contamination from oil or coolant leaks – oxygen sensors live in an a very inhospitable environment.
If your car’s check engine light comes on and you're noticing poor fuel economy, sluggish acceleration, or even a sulfuric "rotten egg" smell from the exhaust, you could be dealing with a failing oxygen sensor. Don’t wait too long to get it checked—continuing to drive with a bad sensor can damage your catalytic converter and lead to more expensive repairs.
