It should also be the same brand.
Changing oxygen sensor.
It could be a funky oxygen o2 sensor.
The ecu then adjusts the.
If the sensor after the catalytic converter shows minimal changes from the reading on the first oxygen sensor it is a sign that the catalytic converter is not working properly.
If your check engine light is constantly trying to get your attention one possible problem could be a bad o2 sensor.
After all if you have a bad or failing o2 sensor you could get reduced gas mileage or even fail an emissions inspection.
A bad or failing oxygen sensor will have a negative impact on environmental emissions and engine performance so there are a 3 things to watch out for before your oxygen sensor completely fails.
