Product features Crankcase ventilation pressure sensor

Product presentation

The sensor measures the pressure difference between that in the crankcase and atmospheric pressure, then transmits this signal to the engine control device. The latter uses this information to detect any possible leak from the crankcase ventilation device.

The sensor has integrated temperature and pressure characteristics, as well as high precision, high sensitivity, reliable stability, low power consumption, and ensures security and reliability. These attributes enable accurate detection of crankcase ventilation system leaks, helping to maintain engine performance and efficiency while ensuring safe and reliable vehicle operation.
