Stricter environmental controls and the requirement to create less pollution has led to far more complex automotive exhaust systems. One component of these systems is the oxygen sensor or Lambda ...

Understanding how oxygen sensors work will help you diagnose problems without having to rely completely on a repair shop. Oxygen sensors act as low-voltage producers, such as how a microphone uses ...

Don't let failing oxygen sensors compromise your engine's performance. O2 sensors are critical to emissions control on your car, SUV or truck. As the name implies, the O2 sensor (also called an ...

Modern car engine control systems rely on input from several sensors to regulate the engine’s performance as well as its emissions and other vital functions. When these sensors fail to provide ...

OXYGEN deficiency is one of the most common of all categories of atmospheric hazards. It stands to reason that the sensors used to measure oxygen concentration are one of the most widely used types of ...

Why Replace A Faulty Oxygen Sensor? A faulty sensor cannot transmit accurate data to the car's computer, causing the engine to run unbalanced. An unbalanced engine either burns fuel with too much or ...

Computers can only do what they are programmed to do. If they get garbage in, they put garbage out. In an automotive engine control computer (called a Powertrain Control Module or PCM; what’s ...

Computer controlled systems continually monitor the operating condition of today's vehicle. Through sensors, computers receive vital information about a number of conditions, allowing minor ...

Last month we fielded a question about a fault code a reader had been trying to repair for more than a year. To recap, the Corvette in question, a ’96 model, had a recurring P0171 code, or “System Too ...
