Product Overview
The low pressure sensors on your Kobelco SK200-10 or SK220XD-10 excavator are critical components that monitor hydraulic system pressure at various points throughout the machine. These sensors provide real-time pressure data to the machine controller, enabling precise hydraulic control, system protection, and operator feedback. The LC13E01562P5 Low Pressure Sensor Wiring Harness is the dedicated electrical harness that connects these sensors to the main machine harness and controller.
This specialized harness is designed specifically for the low pressure sensor circuits on the SK200-10 and SK220XD-10 models. The SK220XD-10 is powered by the HINO J05ETG engine, a four-stroke liquid-cooled direct injection diesel engine with turbocharger and intercooler . The machine features a sophisticated hydraulic system with two variable displacement piston pumps and one gear pump, producing a maximum discharge flow of 2 x 220 L/min plus 1 x 20 L/min . This advanced hydraulic system relies on accurate pressure readings from multiple sensors to maintain optimal performance and efficiency.
Operating in the harsh environment of the excavator’s hydraulic compartment, the low pressure sensor harness is exposed to heat, moisture, vibration, and potential contact with hydraulic oil. Over time, the harness can experience wire chafing, connector corrosion, or insulation breakdown, leading to intermittent or complete loss of sensor signals. Installing a new LC13E01562P5 harness restores proper electrical connectivity to the low pressure sensors, ensuring accurate pressure monitoring and reliable machine operation.

Low Pressure Sensor Applications on SK200-10/SK220XD-10
The LC13E01562P5 harness connects to multiple low pressure sensors throughout the excavator’s hydraulic and control systems. Some recent Kobelco models utilize low pressure sensors for the following functions :
-
Low Pressure Sensors: These sensors monitor lower-pressure circuits for pilot pressure, which is used to control the main spools in the control valve.
-
Location on Valve: The sensors are typically screwed directly into the main control valve body.
Low pressure sensors are critical for the excavator’s electro-hydraulic control system. They allow the machine controller to:
-
Monitor Pilot Circuit Pressure: Ensuring adequate pilot pressure is available to shift main control valve spools when joysticks are operated.
-
Detect System Abnormalities: Identifying low pressure conditions that could indicate leaks, pump issues, or filter restrictions.
-
Enable Proportional Control: Providing feedback for smooth, proportional hydraulic response to operator commands.
-
Trigger Safety Alerts: Activating warnings or protection modes when pressure readings fall outside acceptable ranges.
Signs Your Low Pressure Sensor Harness Needs Replacement
The low pressure sensor harness is subject to gradual degradation due to environmental exposure and machine operation. Replace your LC13E01562P5 harness if you observe:
-
Low Pressure Fault Codes: The monitor panel displays diagnostic trouble codes related to low pressure sensor circuits, such as “Low Pressure Sensor Open” or “Low Pressure Sensor Short.”
-
Intermittent Pressure Warnings: The low pressure warning light or alarm activates intermittently without any actual pressure issue present.
-
Erratic Hydraulic Operation: The excavator’s hydraulic response is inconsistent, with sudden changes in speed or power that correlate with sensor signal loss.
-
Reduced Digging Performance: The machine may operate at reduced power or in limp mode due to the controller receiving invalid pressure readings.
-
Visible Harness Damage: Cracked, melted, frayed, or chafed wire insulation visible on the sensor harness, particularly near the main control valve area.
-
Corroded Connectors: Corrosion visible at the sensor connector or at the interface with the main harness.
-
Sensor Replacement Does Not Resolve Issue: If replacing a low pressure sensor does not clear a fault code, the harness is often the root cause.
-
Intermittent Symptoms: Pressure-related problems that come and go, especially when the harness is moved or during machine operation, indicate wiring issues.

Installation Tips
-
Identify the Correct Harness: Before removal, verify that the LC13E01562P5 is the correct harness for your machine’s low pressure sensor circuit configuration. Compare connector shapes and wire counts.
-
Photograph Routing: Take reference photos of the original harness routing before removal, noting all cable tie positions and clip locations.
-
Tag Connectors: Label each connector as it is disconnected, noting which sensor it serves.
-
Route the New Harness: Follow the factory routing path exactly, keeping the harness away from hot surfaces, moving parts, and sharp edges.
-

-
Verify Connections: Ensure all connectors lock securely into place with an audible click.
-
Test Operation: After installation, start the machine and verify that low pressure fault codes are cleared and pressure readings appear normal on the monitor.
-
Clear Fault Codes: Use a diagnostic tool to clear any stored low pressure sensor-related fault codes after harness replacement.
