What happens if you don’t replace oxygen sensor?
If an oxygen sensor fails, the engine computer won’t be able to correctly set the air-fuel ratio, which could result in lower fuel economy, higher emissions and damage to other components, such as an overheated catalytic converter.
What causes an oxygen sensor to fail?
O2 sensor failures can be caused by various contaminants that enter the exhaust. These include silicates from internal engine coolant leaks (due to a leaky head gasket or a break in a cylinder wall or combustion chamber) and phosphorus from excessive oil consumption (due to worn rings or valve guides).
What does a car do when the oxygen sensor is bad?
If your vehicle has a bad oxygen sensor, it could run irregularly or sound rough when it idles. A faulty oxygen sensor can impact your engine’s timing, combustion intervals, and other essential functions. You could also notice stalling or slow acceleration.
How do I know if I need an upstream or downstream oxygen sensor?
The upstream oxygen sensor is situated before the catalytic converter whereas the downstream oxygen sensor is located after the catalytic converter. Knowing the location of the oxygen sensor at fault is important. The number and location of the oxygen sensors are specific to every vehicle’s year, make and model.
Can you drive a car with a faulty oxygen sensor?

Can I use carb cleaner on sensors?
You can‘t use carburetor or brake cleaners on a MAF sensor, as the chemicals in those cleaners can destroy the delicate sensors. Instead, a special MAF sensor cleaner is required. First, NEVER use MAF cleaner with the engine running or even with the key in the run position. This can cause major damage to the sensor.
Can I use EGR cleaner on MAF sensor?

What can I use instead of MAF Sensor Cleaner?
Any electronic contact cleaner should work well enough, but CRC MAF cleaner is definitely your best chance if you can find it. Alternatively you could use 99% isopropyl alcohol. I would stay away from using carb or brake cleaner, they might harm the plastic parts of the sensor.
Can I use alcohol to clean my mass airflow sensor?
Spray the alcohol liberally over the MAF sensor. Be sure to cover the MAF sensor’s wires, intake and all its crevasses to thoroughly clean the part. Do not touch or scrub the MAF sensor’s wires because they are very delicate and could break. The alcohol will remove all the impurities on its own.
