The 860149905 Oil Pressure Sensor is a genuine XCMG engine management component designed for GR series motor graders. This precision sensor monitors engine oil pressure in real time, providing critical data to the ECU for protection and warning systems. The 860149905 oil pressure sensor is manufactured with a stainless steel diaphragm, a piezoresistive sensing element, and a robust thermoplastic housing, offering exceptional accuracy and durability under high-vibration conditions. Used as original equipment on XCMG GR2003, GR215, GR300, and GR350 graders powered by XCMG XC6B or XC6D diesel engines, this sensor directly replaces leaking, drifting, or failed units, restoring correct oil pressure monitoring and preventing catastrophic engine damage. Each sensor is 100% tested for pressure linearity, temperature compensation, and electrical output.
The 860149905 Oil Pressure Sensor features a 1/8-27 NPT threaded port with an integral sealing washer, and a 3-pin Deutsch DT series connector. Its output is a linear analog voltage (0.5–4.5V) proportional to oil pressure from 0 to 10 bar (0–145 psi). Replacing a failed sensor with the genuine 860149905 part eliminates low oil pressure warnings, false alarms, and engine derate conditions. Each sensor is supplied in an anti-static bag with a protective cap. Whether you are troubleshooting an intermittent oil pressure warning or performing a full engine overhaul, this genuine XCMG component ensures a perfect fit and long service life.
Every 860149905 oil pressure sensor is laser-etched with the XCMG part number and a production date code. The sensor is packed in a foam-lined box. Keep a spare sensor in your parts inventory for rapid diagnostics and replacement.

Genuine XCMG oil pressure sensors are critical for engine protection. Their precise measurement and robust construction outlast generic sensors, ensuring accurate oil pressure monitoring and preventing costly engine failures.
Aftermarket oil pressure sensors often use low-quality piezoresistive elements that drift with temperature or fail under vibration. The genuine 860149905 Oil Pressure Sensor from XCMG is manufactured to Bosch standards, with each sensor individually temperature-compensated. Independent tests show that OEM sensors maintain accuracy within ±2% FS over 10,000 hours, while generic sensors can drift by ±10% after 2,000 hours, causing false low-pressure warnings or, worse, failing to alert a real low-pressure condition. This reliability prevents catastrophic engine bearing failure.
Each 860149905 oil pressure sensor is traceable to its production batch, with records of pressure linearity, temperature compensation, and electrical response. The sensor body is laser-etched with the XCMG part number. XCMG’s quality control includes 100% testing at five pressure points and three temperature points, as well as vibration and thermal shock screening. Only sensors that meet all specifications are shipped, ensuring a perfect match for your grader’s ECU calibration.
Replacing the 860149905 oil pressure sensor requires basic hand tools. Locate the sensor on the engine block or oil filter housing. Disconnect the electrical connector by depressing the locking tab. Unscrew the sensor using a 22 mm deep socket or wrench. Clean the port threads and apply a small amount of thread sealant (do not use PTFE tape near the sensing hole). Install the new sensor with a new sealing washer (included). Torque to 15 Nm. Reconnect the electrical connector. Start the engine and verify live data (oil pressure should rise immediately). Clear any fault codes using a diagnostic tool.
Inspect the 860149905 sensor every 2,000 operating hours. Look for signs of oil leakage around the threads, damaged electrical connector, or erratic readings. If the engine shows symptoms such as fluctuating oil pressure gauge or intermittent warning light, check the sensor’s live data. Replace the sensor if the reading deviates more than 0.3 bar from a mechanical gauge at idle. Keep a spare sensor in your parts inventory for rapid diagnostics.
A 36-month field study on 20 XCMG GR2003 graders in a heavy construction fleet compared genuine 860149905 oil pressure sensors against aftermarket units. Graders with OEM sensors maintained accurate pressure readings (within ±0.2 bar of a master gauge) for 12,000 hours, with no sensor-related failures. Aftermarket sensors showed pressure drift of up to 0.8 bar after 3,000 hours, triggering false low-pressure alarms and causing unnecessary engine shutdowns. The OEM sensors also resisted corrosion and oil contamination, while 40% of aftermarket sensors leaked through the connector. The total cost of ownership using genuine XCMG sensors was 60% lower over three years due to reduced diagnostic time and avoided false shutdowns.
Laboratory tests confirmed that the 860149905 sensor’s stainless steel diaphragm withstands over 30 bar burst pressure, providing a safety margin of 3x. The sensor’s output response time of <5 ms allows the ECU to detect sudden pressure drops (e.g., from a broken oil line) and shut down the engine before damage occurs. For graders operating in extreme cold, the sensor's compensation ensures accurate readings down to -40°C, preventing false warnings during warm-up.
XCMG produces the 860149905 oil pressure sensor in an IATF 16949-certified facility using Bosch-licensed technology. The sensing die is laser-trimmed at wafer level, then assembled onto a stainless steel diaphragm. The sensor is calibrated on a fully automated test bench at 5 pressure points and 3 temperature points. Each sensor is then aged thermally (24 hours at 125°C) and re-tested to verify stability. Random samples are subjected to 2000-hour thermal cycling (-40°C to +125°C) and 1 million pressure cycles. The connector is sealed with a silicone grommet and tested for IP67 compliance.
All genuine 860149905 sensors are individually packed in anti-static bags with desiccant, then placed in foam-lined boxes. Bulk orders of 20 sensors are boxed. XCMG maintains regional stock in Singapore, Houston, and Hamburg, enabling 48-hour delivery to most global destinations. For fleet operators, consignment stock and emergency air freight are available via the buttons above. A 12-month warranty against manufacturing defects is included.
The 860149905 oil pressure sensor directly replaces original XCMG part numbers 860149900 and 860149902, as well as Bosch part number 0 261 230 159. It is fully compatible with GR series graders equipped with XCMG XC6B and XC6D diesel engines (6-cylinder, 5.9L to 6.7L). This sensor is used on the main oil gallery or oil filter housing. For different pressure ranges (e.g., 0-15 bar for high-performance engines), use part 860149906. Always confirm engine model and ECU software version before ordering.
When replacing a sensor, also inspect the wiring harness for damage and clean the connector terminals. XCMG recommends replacing the sensor if the engine has experienced a major bearing failure (contamination). Keep a spare sensor and a pigtail connector kit (860149907) in your parts warehouse. Provide your grader’s serial number and engine number when ordering to ensure correct sensor calibration.
Investing in the genuine 860149905 oil pressure sensor reduces total operating costs by preventing engine damage from undetected low oil pressure. A failed sensor that fails to alert low pressure can lead to spun bearings, crankshaft damage, and engine replacement – costs exceeding $10,000. The OEM sensor, priced competitively, eliminates that risk and provides three times the service life of aftermarket units. Fleet managers who switched to genuine XCMG sensors reported a 99% reduction in false low-pressure alarms and a 50% reduction in engine bearing failures.
When you choose the authentic 860149905 oil pressure sensor, you support sustainable manufacturing. XCMG uses recyclable plastics, lead-free solder, and low-waste calibration processes. The sensor’s long service life reduces electronic waste compared to cheap sensors that need replacement every 3,000 hours.
