If you’re like most people, you probably know very little about your car’s air fuel ratio sensor. But what if I told you that this little piece of equipment is responsible for ensuring that your engine runs smoothly and efficiently? Let’s go over what an air-fuel ratio sensor is, where it’s located, what it does, … Read more
Combustion engines are not machines that you can tune perfectly and then expect to run that way forever. They need constant readjusting to run efficiently. Technology in modern cars works to make these small adjustments as you drive. Sometimes, even the most advanced systems cannot correct a problem that develops in your engine. When the … Read more
When you drive, your engine uses a combination of sensors to know exactly how much air and oxygen to release into the combustion chambers at any given time. The fuel and oxygen needs change as you speed up, rev the engine harder, or travel at higher altitudes. Specifically, the powertrain control module (PCM) receives information … Read more
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
Your vehicle’s air-to-fuel ratio is critical for your engine performance. If you don’t have the correct air-to-fuel ratio in your vehicle, you can seriously damage your engine. If an OBD2 scanner is indicating a P2096 code, it means there is a problem with your air-to-fuel ratio. Most modern engines have two different oxygen sensors that … Read more
Your engine needs the right ratio of fuel to air to run efficiently. If there’s either too much or not enough, then your combustion engine will not work as well or efficiently as it’s supposed to. When there is too much air entering the chambers, your vehicle will store a P0171 code. A variety of … Read more
Maintaining the correct air-fuel ratio is important for getting the best performance and fuel economy from your engine. When this ratio is incorrect, your engine runs rich or lean and could cause damage. In this article, we’ll go over typical ideal air-fuel ratios under various conditions. What is an Air-Fuel Ratio? The air-fuel ratio (AFR) … Read more
