Modern cars rely on a dense web of sensors to manage everything from fuel delivery to collision avoidance, and when one fails, the result can range from a minor annoyance to a four-figure repair. I ...

Knowing a few precise mechanic terms can turn a confusing estimate into a clear conversation and keep you from paying for work you do not need. By understanding what these 14 concepts actually mean, ...

Oxygen sensors detect the amount of oxygen in the exhaust. Oxygen sensors usually don’t have a replacement schedule. A bad oxygen sensor can be diagnosed with a code reader or scan tool. A car’s ...

This whitepaper explores the role of process analytical technology (PAT) in enhancing the efficiency of upstream ...
