Fuel smell under the hood or a stubborn check-engine light often points to a bad fuel-pressure sensor, but nothing stalls a ...

Tire pressure monitoring systems (TPMS) help keep your car safe by alerting you to under-inflated tires. But knowing whether ...

Acoustic vector sensors (AVSs) can be employed to improve low-frequency performance of the sensor array against aperture limitation, due to their configurations that allow for the simultaneous ...

Air leaking into your car—not out of it—can be a problem. Popular Mechanics’s automotive experts outline the tools and techniques proven to smoke out even the toughest to find vacuum leaks.

Because the pressure inside the manifold can change based on driving conditions, the sensor must constantly send data to the ECM. The MAP is able to do this thanks to its construction. Inside, it ...

The pressure inside the sample inlet is monitored by the first pressure transducer. This sensor allows the Lasair III to measure and correct for the vacuum generated by the manifold pump. A ...

The manifold absolute pressure sensor, also known as the MAP sensor, is an important part of the car’s engine management system. The MAP sensor is found in vehicles with fuel injection, and the ...

However, when it comes to finding and accessing the boost pressure sensor, it’s one of the easier components on most vehicles. Boost Pressure Sensor Replacement Cost. The average boost pressure sensor ...
