the check engine light will come on
Replace both of them.
When the oxygen sensor goes bad, the check engine light goes on.
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.
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.
Go to the auto parts store and buy a scanner OBD1 or OBD2 and it will let you know why your check engine light is on and if the o2 sensor is bad
Engine check light comes on, and you have the codes read.
The check engine light would come on.
Stop by your local AutoZone. They will hook it up to a handheld tester and print out which oxygen sensor is failing.
how do you k now the cam sensor is bad
An auto xray scanner can determine if a O2 sensor is bad.
bad idle and chec engine light comes on. this can be checked with and obd 1 code reader
It sure can.
When you have a bad oxygen sensor your car may consume a lot of gas. Your car may also drive slower.
No, it is not a knock sensor at all. An AF (Air/Fuel Ratio) sensor is also know as a wide range oxygen sensor. It is the newer type oxygen sensor.
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
Yes it can!
yes..a bad oxygen sensor can/will make your car stall at idle speed
I don't know the cost of the sensor but it is just a mamtter of unplugging the old one, unscrewing it and installing the new one. GoodluckJoe
The oxygen sensor on any vehicle is located on under the car on the top of the muffler pipe just behind the cadallidic converter....do you know what the oxygen sensor looks like so you know what you're looking for?
Unfortunately there is no fixing an O2 sensor. If the "check engine" light is on due to an O2 sensor, it can only be remedied by replacing the bad sensor.
how do i know if the o2 sensor is bad. The check engine light would illuminate and the code(s) set would steer you to the faulty O2 sensor.
When a crankshaft sensor is bad the engine will not run. The sensor is not usually intermittent, it is either good or bad.
Could be a diesel? If not then replace your oxygen sensor on your exhaust. A bad oxygen sensor causes the exhaust smoke to be dark in color.
