This Design Idea describes a method by which you can detect and assess air or liquid fluid flow using an externally heated semiconductor diode. Airflow across the heated diode reduces its temperature, ...

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 ...

P0134 – O2 Sensor Circuit No Activity Detected Sensor 1 Bank 1: The front heated oxygen sensor (or O2 sensor 1) is placed into the exhaust manifold. It detects the amount of oxygen in the exhaust gas ...

Today’s computerised engine control systems rely on inputs from a variety of sensors to regulate engine performance, emissions and other important functions. The sensors must provide accurate ...

When we got the invitation to tour Bosch's oxygen sensor plant in Anderson, South Carolina, it had all the allure of eating a sand sandwich. Let's face it, oxygen sensors aren't the most glamorous ...

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 ...

Unscrewing a sensor and replacing it is pretty straightforward. You might need this special socket to clear the wires. Twelve years and more than 100,000 miles have passed under your trusty commuter ...

Your car's computer uses data from the O2 sensors to determine the effectiveness of the catalytic converter and how much fuel to inject. So they're critical pieces. Luckily, replacing one is ...

Q:Hi James. I keep having an oxygen sensor fault code for a lean exhaust with my '97 Corvette. I've taken the vehicle to the dealer several times but the problem keeps recurring. I would like to try ...
