Pressure Sensor
Cummins®

A Pressure Sensor, also known as a pressure transducer, is an electronic device that measures the pressure of a fluid or gas and converts it into an electrical signal. This signal is then sent to the engine control module (ECM) to regulate fuel injection and ignition timing. The 5613430 Pressure Sensor is designed specifically for use in trucks and other heavy-duty vehicles, where it plays a critical role in ensuring optimal engine performance and fuel efficiency. It typically consists of a diaphragm that deforms under pressure changes, causing an attached strain gauge to generate an electrical output proportional to the applied force. The ECM uses this information to adjust engine parameters such as turbocharger boost pressure, exhaust gas recirculation (EGR), and variable geometry turbo (VGT) actuation. A faulty Pressure Sensor can result in poor acceleration, reduced fuel economy, and increased emissions levels.
