Also, is an A F sensor the same as a o2 sensor?
An air/fuel sensor can read a much wider and leaner range of fuel mixtures than a conventional O2 sensor. That's why they're also called “wideband” O2 sensors. An A/F sensor, by comparison, produces a changing current signal that varies in direct proportion to the amount of unburned oxygen in the exhaust.
Furthermore, can you clean an air fuel sensor? A dirty oxygen sensor can cause your “check engine” light to come on, and can also result in your car burning through extra gasoline. If you suspect that your oxygen sensor may be dirty, you can clean it by first removing the sensor from its housing in the vehicle, and then soaking the sensor in gasoline overnight.
Also know, what are the symptoms of a bad oxygen sensor?
Symptoms of a Bad or Failing Oxygen Sensor
- Check Engine Light comes on. The first line of defense is the Check Engine Light.
- Bad gas mileage. If the oxygen sensor is going bad, the fuel-delivery and fuel-combustion systems will be thrown off.
- Rough engine idle and misfires.
Can I use a downstream oxygen sensor for upstream?
A downstream oxygen sensor in or behind the catalytic converter works exactly the same as an upstream O2 sensor in the exhaust manifold. On some newer vehicles, a new type of wide ratio air fuel sensor is used.
