Pressure Sensor 31CP52-01 80100-1207360E6R for Yuchai Engine
Pressure Sensor 31CP52-01 80100-1207360E6R – Direct Replacement for Yuchai Engine
Product Overview
This heavy-duty pressure sensor is engineered as a direct OEM-equivalent replacement for Yuchai diesel engine systems. Designed for high-accuracy pressure monitoring in fuel rails, common-rail injection systems, and hydraulic circuits, the 31CP52-01 80100-1207360E6R ensures stable signal output under extreme vibration, temperature fluctuation, and pressure spikes.
Built with a stainless-steel sensing element and robust polymer housing, this sensor meets original equipment fit, form, and function requirements. It is ideal for fleet maintenance, engine rebuilds, and aftermarket service kits.
Key Benefits
Plug-and-play compatibility with Yuchai engine harnesses (no adapter required)
Wide operating range – supports pressures from 0 to 52 MPa absolute
Fast response time (< 2 ms) for real-time ECU closed-loop control
High overpressure tolerance – withstands up to 2× rated range without damage
Temperature compensated from –40°C to +125°C for global climate reliability

Installation Guidelines (for technicians)
Always disconnect the battery before replacing the sensor.
Clean the mounting port thoroughly – debris can damage the diaphragm.
Apply light grease to the new O-ring (not included in all packaging).
Torque the sensor to 25–30 N·m – overtightening may distort the thread.
Reconnect the 3-pin connector until you hear a positive click.
Perform a key-on/engine-off voltage check – expect 0.5 V (no pressure).
Start engine and monitor live data for linear pressure increase with RPM.
