One of the most important measurements we make while tuning an engine is finding out what the actual balance of air and fuel was inside the engine. It doesn’t matter if we have a carburetor, port ...

If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard the term “wideband O2 sensor” being thrown around at the track, dyno ...

In a performance application at wide open throttle, the ECU needs to control the air to fuel ratio to hit a small target somewhat richer than stoichiometric. The narrowband sensors most OEs use only ...

The P0118 code means that the engine control module (ECM) has detected a voltage signal that’s too high from the engine coolant temperature (ECT) sensor (below). In practical terms, the ECM believes ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

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 ...

As a vital component of a vehicle’s emissions control system, oxygen sensors play a crucial role in engine performance and fuel efficiency. But what’s the typical cost to replace a failed O2 sensor?

Abstract: A wideband amplitude variation-based displacement sensor with wide dynamic range is presented in this paper. The sensor is designed using a microstrip transmission line loaded with a ...

Abstract: Human behavior analysis in indoor environments from ambient sensor data is one of the most challenging human-machine interaction research topics. In this paper, we present a deep ...

The oxygen sensors are a vital part of measuring the amount of oxygen in the gas. If there’s something wrong with the oxygen sensor, the Check Engine Light is sure to come on, which can be annoying.
