What is the difference between air-fuel ratio sensor and oxygen 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. Another difference is that A/F sensors don’t produce a voltage signal that suddenly changes on either side of Lambda when the air/fuel goes rich or lean.
When to replace an air fuel ratio sensor?
If you notice a decrease in fuel efficiency or engine power output, as well as a rough idle, you may have to replace any air-fuel ratio sensors. 1. Decrease in fuel efficiency
How is air conditioning technology changing the world?
Air conditioning technology is getting cleaner and greener. But demand is growing so quickly that – even if the optimists are right about possible efficiency gains – there’ll be an eightfold increase in energy consumption by 2050. That’s worrying news for climate change.
When to reset the ECU after changing an O2 sensor?
Sometimes an O2 sensor fails, and you need to replace it. Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor.
How to check and replace an oxygen sensor ( air )?
A P1155 or P1135 code indicates you have a bad sensor. This is common in Toyota and Lexus cars and trucks. Learn how to test the air fuel ratio sensor to see if it is bad, and then learn how to replace the bad sensor. Nice O2 Sensor Socket Kit: http://www.amazon.com/gp/product/B005…
How does the computer change the fuel ratio?
The computer uses input from its various engine sensors to regulate fuel metering and to change the air/fuel ratio in response to changing operating conditions. The primary sensor for real-time adjustment to air/fuel mixture is the upstream oxygen sensor.
How do you remove an air fuel sensor?
Use your breaker bar and the air fuel ratio sensor socket and remove the sensor from the exhaust pipe. Some air fuel ratio sensors may get stuck onto the exhaust pipe and make it almost impossible to remove. At this time, you would need to have a small portable torch handy.
