Air and fuel are the heart of the internal combustion process. The proper amount of air and fuel must enter the internal combustion chamber if the ignition is going to be successful. Otherwise, you might have a situation where your engine either consumes too much fuel or under performs. The engine control unit (ECU) normally … Read more
Oxygen sensors are able to function properly because of certain heating components that are built into them. A heater circuit is what drives these elements to produce the necessary heat. If there is a short in the heater circuit or if it faces tough resistance, then it could cause the running engine to be rough. … Read more
In this article we are going to go over a very important sensor in a car’s engine called the “oxygen sensor”, commonly referred to as an O2 sensor. Afterwards, you should know the basic function, working principle, bad symptoms, and average replacement cost of an oxygen sensor. How an Oxygen Sensor Works The internal combustion … Read more
There are oxygen sensors positioned all throughout the exhaust system of a vehicle. Their job is to keep track of the air levels within the exhaust fumes of the system. As these sensors detect the air level, they send this information to the powertrain control module. From there, the module will know how much air … Read more
Modern vehicles have oxygen sensors in them, also known as O2 sensors. Their overall purpose is to measure the amount of air in the exhaust system while the exhaust gases are coming out of the engine. The engine control unit is the computer which regularly monitors and communicates with these sensors. O2 sensors will tell … Read more
An internal combustion engine can only function at the top of its game when the air to fuel ratio is just right. When air and fuel get mixed together, there must be roughly 15 parts of air for every 1 part of fuel. The engine control unit is responsible for making sure the engine is … Read more
