DOCUMENT TECHNICAL CONTENTS & VERIFIED SCHEMATIC / PCB PREVIEW
VERIFIED ENGINEERING SPEC
This 3-page technical document provides a comprehensive fault code list for Weichai natural gas engines. It maps internal SFC codes to FMI and CAN SPN values for critical sensors like UEGO, NGT, XDRP, and MAP, aiding in precise CNG system diagnostics.
WHAT IS INSIDE THIS DOCUMENT (CIRCUITS, PINOUTS & SECTIONS):
- UEGO (Universal Exhaust Gas Oxygen) sensor heater and calibration faults
- NGT (Natural Gas Temperature) sensor voltage and rate of change diagnostics
- XDRP (Exhaust Differential Pressure) sensor high and low voltage faults
- MAP (Manifold Absolute Pressure) and MAF (Mass Air Flow) sensor diagnostics
- TPS (Throttle Position Sensor) and ECT (Engine Coolant Temperature) faults
- CNG (Compressed Natural Gas) pressure and temperature sensor diagnostics
- System overpressure and secondary EEPROM memory fault codes
