It messes up your fuel economy therefor burning more gas and will also trip your check engine light. It may have a smell to it and run a bit crappy.
When the oxygen sensor goes bad, the check engine light goes on.
When an oxygen sensor goes bad a car will burn gas at a higher than normal rate because it will not be producing as much power as before. The oxygen sensor checks the amount of exhaust.
An auto xray scanner can determine if a O2 sensor is bad.
It sure can.
When you have a bad oxygen sensor your car may consume a lot of gas. Your car may also drive slower.
There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.
bad oxygen sensor bad map sensor
the check engine light will come on
Yes it can!
Replace both of them.
yes..a bad oxygen sensor can/will make your car stall at idle speed
An oxygen sensor is bad when it is no longer performing inside a set of parameters that are designated and optimal. The oxygen operates in a very narrow window of voltage and provides feedback to the engine to adjust the air/fuel ratio to maintain performance and emissions. If the sensor is bad and returning poor data, the performance, emissions and mileage will suffer.
