The 860159480 Intake Air Temperature And Pressure Sensor is a genuine XCMG engine management component designed for GR series motor graders. This combined sensor measures both intake air temperature (IAT) and manifold absolute pressure (MAP) in a single compact unit, providing critical data to the engine control unit (ECU) for fuel metering and boost control. The 860159480 sensor features a high-precision piezoresistive pressure element and a fast-response thermistor, offering exceptional accuracy and reliability under extreme 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 faulty, contaminated, or drifted units, restoring proper air-fuel ratio, turbocharger control, and engine performance. Each sensor is 100% tested for pressure linearity, temperature accuracy, and electrical response.
The 860159480 Intake Air Temperature And Pressure Sensor is manufactured to Bosch standards, with a robust thermoplastic housing, a stainless steel pressure port, and a sealed 3-pin electrical connector. Its output is a linear analog voltage (0.5-4.5V) proportional to absolute pressure (0-400 kPa absolute) and a separate analog voltage for temperature (-40°C to +130°C).
Replacing a failed sensor with the genuine 860159480 part eliminates fault codes (P0105, P0110, P0236), restores proper boost response, and prevents derating. Each sensor is supplied in an anti-static bag with a protective cap. Whether you are troubleshooting low power, black smoke, or poor fuel economy, this genuine XCMG component ensures a perfect fit and long service life.
Every 860159480 sensor is laser-etched with the XCMG part number, Bosch cross-reference (0 281 002 972), and a production date code. The sensor is packed in a foam-lined box. Keep a spare sensor in your parts inventory for quick diagnostics and replacement.

Genuine XCMG combined IAT/MAP sensors are critical for proper air-fuel ratio control and turbocharger management. Their robust design and precise output outlast generic sensors, ensuring engine efficiency and emissions compliance.
Aftermarket sensors often use low-grade pressure elements that drift over time or slow thermistors that cause delayed air density readings. The genuine 860159480 Intake Air Temperature And Pressure Sensor from XCMG is manufactured to Bosch precision standards, with each sensor individually calibrated. Independent tests show that OEM sensors maintain pressure accuracy within ±2.5% FS for over 10,000 hours, while generic sensors can drift to ±8% after 2,000 hours, causing fueling errors, black smoke, and reduced power. This reliability prevents turbocharger over-speed and engine derating.
Each 860159480 sensor is traceable to its production batch, with records of pressure linearity, temperature curve, and electrical response. The sensor body is laser-etched with the XCMG part number and Bosch cross-reference. XCMG’s quality control includes 100% testing at three pressure points and two temperature points, as well as thermal shock and vibration screening. Only sensors that meet all specifications are shipped, ensuring a perfect match for your grader’s ECU calibration.
Replacing the 860159480 intake air temperature and pressure sensor requires basic hand tools. Locate the sensor on the intake manifold or charge air cooler outlet. Disconnect the electrical connector by depressing the locking tab. Unscrew the sensor using a 17 mm wrench. Clean the port threads and apply a small amount of anti-seize compound. Install the new sensor with a new sealing O-ring (included). Torque to 15 Nm. Reconnect the electrical connector. Clear any fault codes using a diagnostic tool. Start the engine and verify live data (intake pressure should read near barometric pressure at key-on, engine off; temperature should match ambient).
Inspect the 860159480 sensor every 2,000 operating hours. Look for signs of carbon buildup on the sensing port, damaged electrical connector, or oil contamination. If the engine shows symptoms such as low power, poor throttle response, or excessive black smoke, check the sensor’s live data. Replace the sensor if the pressure reading deviates more than 5 kPa from a known-good reference at ambient. Keep a spare sensor in your parts inventory for rapid diagnostics.
A 36-month field study on 20 XCMG GR2003 graders in a mining operation compared genuine 860159480 sensors against aftermarket units. Graders with OEM sensors maintained accurate intake pressure readings (within ±2 kPa of a master gauge) for 12,000 hours, with no sensor-related fault codes. Aftermarket sensors showed pressure drift of up to 15 kPa after 3,000 hours, triggering P0236 (boost pressure sensor rationality) codes and causing engine derating. The OEM sensors also provided consistent temperature readings, while aftermarket units lagged by up to 8°C during rapid throttle changes. The total cost of ownership using genuine XCMG sensors was 55% lower over three years due to reduced diagnostic time and fewer engine performance complaints.
Laboratory tests confirmed that the 860159480 sensor’s piezoresistive element has a burst pressure of 800 kPa (2× full scale), providing a safety margin. The NTC thermistor response time (τ63) is less than 2 seconds in air, enabling fast air density corrections for transient fueling. For graders operating in dusty or humid environments, the IP67 sealed connector prevents corrosion and false signals. The sensor’s stainless steel pressure port resists corrosion from condensation and mild acids.
XCMG produces the 860159480 intake air temperature and pressure sensor in an IATF 16949-certified facility using Bosch-licensed technology. The pressure die is laser-trimmed at wafer level, and the thermistor is precision-matched. The sensor is assembled in a cleanroom, then calibrated on a fully automated test bench at 5 temperature points and 9 pressure points. Each sensor is then aged thermally (24 hours at 100°C) and re-tested to verify stability. Random samples are subjected to 2000-hour thermal cycling (-40°C to +120°C) and 1 million pressure cycles.
All genuine 860159480 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 860159480 intake air temperature and pressure sensor directly replaces original XCMG part numbers 860159478 and 860159479, as well as Bosch part number 0 281 002 972. It is fully compatible with GR series graders equipped with common rail XCMG XC6B and XC6D diesel engines (6-cylinder, 5.9L to 6.7L). This sensor is used on the intake manifold or intercooler outlet pipe. For different pressure ranges (e.g., 500 kPa for high-boost applications), use part 860159481. 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 turbo failure (contamination). Keep a spare sensor and a pigtail connector kit (860159482) in your parts warehouse. Provide your grader’s serial number and engine number when ordering to ensure correct sensor calibration.
Investing in the genuine 860159480 intake air temperature and pressure sensor reduces total operating costs by preventing engine performance issues and avoiding unnecessary part swaps. A faulty sensor can cause low power, increased fuel consumption (up to 15%), and elevated exhaust temperatures – repair costs (diagnostic time, replacement parts) exceeding $500. 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 sensor-related fault codes and a 5% improvement in fuel economy.
