Vielhaber’s Garage Can Replace Your Oxygen Sensor When It Goes Bad

The average lifespan of an oxygen (O2) sensor is 100,000 miles in newer automobiles and 30,000 miles in older automobiles. Vielhaber’s Garage is here for all of your automotive service and repair needs including replacing the oxygen sensor. We are going to list below the signs that your O2 sensor has gone bad. Bring your vehicle to our shop at the first sign of trouble.

Black Engine Exhaust

The O2 sensor tracks the oxygen levels in the exhaust. The engine control unit (ECU) uses this data to make adjustments to the air and fuel in the combustion chamber. If the O2 sensor malfunctions, the ECU may put excess fuel in the combustion chamber and you will end up with black exhaust.

Check Engine Warning

The check engine light will also turn on because of the problems listed in this blog post and because the O2 sensor most likely sent the ECU an error code when it went bad. Unfortunately, the check engine light will remain on until you replace the malfunctioning O2 sensor, which we can do.

Failed Emissions Test

Your automobile will fail any emissions test that it takes if the O2 sensor is bad. In fact, one of the reasons why it will fail is that the check engine light is on. The skewed adjustments to the air and fuel that the ECU makes can increase the hydrocarbons in your vehicle’s exhaust.

Faulty Catalytic Converter

They can also damage the catalytic converter and cause it to malfunction. When this happens, your exhaust will start to smell like rotten eggs. You will also notice that the underside of your automobile is extremely hot. In fact, this heat can rise and overheat the engine.

Poor Engine Performance

Anytime the air and fuel are out of balance in the combustion chamber you will end up with poor engine performance. This reduction in your engine’s performance is indirectly caused by the malfunctioning O2 sensor. The ECU will not balance the air and fuel until the oxygen sensor is replaced.

Reduced Fuel Economy

Consequently, you will also see a reduction in your vehicle’s fuel economy because the engine is performing poorly. If there is too much fuel in the combustion chamber, the engine will burn it away. If the engine is fuel-starved, it will still burn excess fuel to generate power.
