Q: What Sumitomo models use the KM16-P03 pressure sensor?
A: The COGENG KM16-P03 pressure sensor is a direct OEM replacement specifically designed for Sumitomo SH200, SH240, and SH250 excavator models. This sensor is typically used in the hydraulic system for monitoring pump discharge pressure, pilot pressure, or other critical pressure circuits. Always verify this part number against your machine's parts manual or the original sensor's identification markings to confirm exact compatibility before ordering.
Q: What are the symptoms of a failing pressure sensor on a Sumitomo excavator?
A: Common symptoms include inaccurate or erratic pressure readings on the monitor panel, active diagnostic trouble codes related to the pressure sensor circuit, degraded hydraulic performance or unexpected power reduction, the machine entering a failsafe or limp mode, intermittent hydraulic function response, or the engine control system failing to properly match engine speed to hydraulic load demand. A faulty pressure sensor can significantly impact overall machine performance, digging force, and fuel efficiency.
Q: How does the pressure sensor affect excavator operation?
A: The KM16-P03 sensor provides real-time hydraulic pressure data to the machine's electronic control system. This information is used to manage pump displacement, engine speed matching, and implement response. Accurate pressure sensing is essential for smooth hydraulic operation, preventing system overloads, and optimizing fuel consumption.
Q: Is this sensor a direct plug-and-play replacement?
A: Yes, the COGENG KM16-P03 sensor is manufactured to exact OEM specifications for thread size, electrical connector type, pressure range, output signal characteristics, and response time. It is a direct plug-and-play replacement requiring no wiring modifications or adapters when installed on compatible Sumitomo excavator models.
Q: What is the warranty coverage for this pressure sensor?
A: COGENG provides a standard 12-month warranty against manufacturing defects from the date of installation. Proof of purchase and installation by a qualified technician are required. Warranty does not cover failure caused by hydraulic fluid contamination, over-pressurization, improper installation, overtightening, thread damage, or use on incompatible equipment.
