C5698455 intake pressure temperature sensor is a dual-function electronic sensing component built for ISF3.8 heavy-duty diesel engine intake system. It simultaneously detects the pressure and temperature of the intake air entering the engine cylinder and converts these physical parameters into electrical signals to transmit to the engine ECU. The ECU analyzes the air density based on the collected data to dynamically adjust fuel injection quantity and timing, optimizing combustion efficiency, lowering fuel consumption and controlling exhaust emissions. When this sensor fails, inaccurate air data will lead to poor combustion, insufficient engine power, excessive smoke emission and fault codes on the dashboard. Serious failure may trigger engine derate mode, limiting vehicle speed and affecting the normal transportation schedule of commercial vehicles. Timely replacement of this sensor ensures precise air-fuel ratio control and stable engine performance. Key features: Dual sensing chip design, fast signal response, high measurement accuracy, robust shock-resistant housing, waterproof plug connector, wide working temperature range, anti-corrosion air inlet structure, OEM plug-and-play specification. Product Advantages: Complete calibration testing before leaving factory; outstanding anti-electromagnetic interference ability; stable reading under continuous engine vibration; perfectly matches original mounting hole and connector; simple installation without harness modification during maintenance.

Applicable Equipment: Light and medium commercial trucks equipped with ISF3.8 diesel engine.
