Over time, your oxygen sensors can become caked with byproducts of combustion like sulfur, lead, fuel additives, and oil ash. This keeps your sensors from sending signals to your engine’s computer. Using fuel that isn’t recommended for your vehicle or low-quality gasoline can make your oxygen sensors fail faster.

What kills an oxygen sensor?
MALFUNCTIONING AND FAILED SENSORS Oxygen sensors can fail when the sensor's ceramic element is exposed to certain types of silicone compounds or when an oil-burning engine leads to the sensor becoming oil-fouled. Also, a small amount of tetra-ethyl lead in the gasoline can kill an oxygen sensor.
How often do O2 sensors go bad?
And lastly, how long do oxygen sensors typically last? Older vehicles have O2 sensors that will typically last 30,000 to 50,000 miles, or 3 to 5 years. Newer vehicles employ sensors with an additional heated element and these new sensors are more likely to last to 100,000 or 7-10 years.
Can coolant damage an O2 sensor?
oxygen sensors can fail if they are contaminated with oil, coolant or other fluids.
Bad Oxygen Sensor Symptoms And Dangers
Why do my O2 sensors keep going bad?
Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak.
What causes sensor failure?
Cable break / lead breakage, broken connectors and damaged cable insulation – many of these failure causesfailure causesFailure causes are defects in design, process, quality, or part application, which are the underlying cause of a failure or which initiate a process which leads to failure.https://en.wikipedia.org › wiki › Failure_causeFailure cause - Wikipedia and sources of errors in sensors can be traced back to mechanical failure of qualitatively inferior components.
Can you still drive a car with a bad O2 sensor?
Can You Drive With A Bad Oxygen Sensor? Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don't leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.
Symptoms Of A Bad Oxygen Sensor
What can damage an O2 sensor?
Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak.
What causes an O2 sensor to keep going bad?
Over time, your oxygen sensors can become caked with byproducts of combustion like sulfur, lead, fuel additives, and oil ash. This keeps your sensors from sending signals to your engine's computer. Using fuel that isn't recommended for your vehicle or low-quality gasoline can make your oxygen sensors fail faster.
O2 Sensors Is It Upstream Or Downstream?
What happens if you drive with a bad oxygen sensor?
A bad oxygen sensor could cause sluggish and rough driving with stalls, along with poor fuel efficiency and high pollution. And if you leave it there for several months, it may lead to serious problems in the engine and catalytic converter which cost thousands of dollars to fix or replace.
What happens if you keep driving with a bad O2 sensor?
A bad oxygen sensor could cause sluggish and rough driving with stalls, along with poor fuel efficiency and high pollution. And if you leave it there for several months, it may lead to serious problems in the engine and catalytic converter which cost thousands of dollars to fix or replace.
