Oil Pressure Sensor L4700-38231G0 NPT14 4P2P Electronic for Yuchai Yutong Engines

Product Appearance Description

This oil pressure sensor features a high-strength metal housing with galvanized anti-rust treatment, offering excellent impact and corrosion resistance. The thread specification is NPT1/4, fully consistent with the installation dimensions of original parts. It fits perfectly into the oil pressure detection positions of Yuchai engines and Yutong passenger buses. Equipped with a 4-pin / 2-pin compatible electronic connector, it allows direct replacement without modification.

Product Function Description

It monitors engine oil pressure changes in real time and transmits data to the ECU or instrument panel, triggering timely alarms when oil pressure is abnormal, effectively protecting the engine from wear and damage caused by insufficient lubrication. With fast response and high precision, the sensor is resistant to high and low temperatures and vibration, adapting to the complex working conditions in the engine compartment, effectively solving common issues such as false oil pressure alarms, no signal, and constant fault light illumination.
