What is an O2 sensor?
The sensor determine s the amount of oxygen in the exhaust system. With a fully functioning O2 sensor, the engine can balance the amount of fuel used. In return, this allows for peak efficiency.
What is an oxygen sensor?
Oxygen sensors are constructed with a ceramic cylinder that’s plated on the inside and outside with porous gas permeable platinum electrode and protected by an exterior shield with either holes or slots. One electrode is exposed to exhaust gas, while the other is exposed to outside air.
What are the two groups of oxygen sensors?
Oxygen sensors fall into two groups; narrow band and wide band . The narrow band sensors, as the name implies detect a very narrow band of oxygen levels, so the computer gets either a “high” or “low” oxygen level reading from the exhaust.
How does a planar sensor work?
A planar sensor is a zirconia sensor with a heater to speed up its ability reach operating temperature. A planar sensor can become active within 12-seconds after the engine is started.#N#Titania. A titania sensor operates differently than a zirconia sensor. Rather than generating 0-1-volts as oxygen concentration varies, the titania sensor changes the input voltage supplied by the PCM through the use of a variable resistor. A variable resistor changes its resistance based on the concentration of oxygen in the exhaust stream. So the PCM supplies 5-volts to the Titania sensor, the variable resistor decreases resistance as it encounters a lean exhaust (more oxygen), which returns a high voltage signal to the PCM. As oxygen levels fall, the sensor increases resistance so the PCM sees a lower return voltage signal. The PCM sees voltage near 5-volts as a lean condition and voltages near 0 as a rich condition.
When is zirconia used to conduct oxygen?
When oxygen concentration is high, it produces up to 1-volt. Zirconia conducts the flow of oxygen ions when the material is above 350°C. The outside of the zirconia cell is exposed to the exhaust gas while the inside is exposed to outside air.
Do wide band sensors use gas pumps?
But unlike narrow band sensors, wide band sensors don’t rely on natural air movement to provide the comparison. They use an electrochemical gas pump to move outside air through the sensor so it can provide a much more accurate comparison.
Can oxygen sensors be cleaned?
None of these oxygen sensors or air fuel ratio sensors can be cleaned in a way that will affect performance. You can clean it to make the exterior shield look shiny. You can spray cleaner on the ceramic element. That may make you feel good.
Can you clean an oxygen sensor?
Technically yes. But in reality no. The pores in the gas permeable electrodes allow oxygen ions to pass through, but they are so small that no cleaning solvent can possibly penetrate and clean them. In other words, if the pores are clogged, they stay clogged. Do a search for cleaning an oxygen sensor and you’ll see all kinds of advice on how to clean oxygen sensors. They’re all worthless.
