Buy Cummins ISX15 QSX15 Diesel Engine Pressure Temperature Sensor 4921473 3417183 3417142 | Tonkee®

The Pressure and Temperature Sensor (PTS) is a vital component of the Cummins ISX15 and QSX15 engines' electronic control system.

It is designed to accurately monitor two critical parameters: pressure and temperature. These measurements are crucial for ensuring engine performance, efficiency, and safety.

Pressure Measurement:
The PTS continuously monitors the intake manifold pressure, which is essential for optimizing the air-fuel mixture in the engine cylinders. This precise measurement enables the engine control unit (ECU) to adjust fuel injection and turbocharger operation in real-time, ensuring that the engine operates within its specified performance range. This not only enhances fuel efficiency but also reduces emissions, making these engines more environmentally friendly.

Temperature Measurement:
In addition to pressure, the PTS also measures temperature. It typically monitors engine coolant temperature. Accurate temperature data is vital for preventing overheating, managing engine warm-up, and optimizing the engine's performance under various operating conditions. If the temperature exceeds safe limits, the ECU can take corrective actions, such as reducing power output or activating cooling systems.

Specifications:

Part Numbers: The Cummins Pressure and Temperature Sensor is available under various part numbers, including 4921473, 3417183, and 3417142, depending on the engine model and application.

Pressure Range: The sensor can measure a wide range of pressures, typically from vacuum (negative pressure) to positive pressure levels required for the engine's operation.
Temperature Range: It is designed to withstand extreme temperature ranges commonly encountered in engine compartments.
Compatibility: These sensors are specifically designed for Cummins ISX15 and QSX15 diesel engines, ensuring precise compatibility and performance.
Durability: Constructed with robust materials and advanced manufacturing techniques, these sensors are built to withstand harsh environmental conditions and mechanical vibrations commonly found in heavy-duty applications.
Importance:
The Pressure and Temperature Sensor is pivotal in ensuring that Cummins ISX15 and QSX15 engines operate at peak efficiency and reliability. Its ability to provide real-time data to the engine control unit enables the engine to adapt to changing conditions, reducing wear and tear, optimizing fuel consumption, and minimizing emissions. Without accurate pressure and temperature monitoring, the engine's performance would be compromised, potentially leading to increased maintenance costs and reduced operational efficiency.
