What happens if u installed a wrong o2 sensors?


Ok I bought some oxygen sensors ( o2 ) on amazon, because mine was going bad, so I installed them everything was normal. Then I realized that car start acting weird. *my gas gage keeps bouncing *i see my transmission light on and then my car went off .

What are the signs of a wrong o2 sensor on a BMW?

The signs of of bad O2 sensors are a check engine light and ODB2 codes that are set for O2 sensor errors.

How did you know they were going bad in the first place?

My gas starts burning bad. It’s like burning waaaaay to fast. I ran the diagnostics and they said yeah it was…

If it’s not the o2 sensors … I’m wondering if it’s the aftermarket wheel sensors that I bought, causing my car to malfunctioning .

Wheel sensors will not cause your car to malfunction. You might see the symbol for low tire pressure.

@Mustangman asked a very good question, why did you replace the O2 sensors? I assume your gas mileage has dropped, but without more information that does not lead to a diagnosis of a bad O2 sensor. What was the car doing , what symptoms did you see, was the check engine light on? If it was was were the codes, post them here, they will look like P1234


Thanks bro appreciate… I will find them and send them
