3. Air Pressure Sensor Troubleshooting & Diagnostic Guide

If your construction machinery system is exhibiting sensor-related failure, consult the diagnostic guide below:

• Fault 1: Machinery Power Drop & Weak Response
  Root Cause: Damaged air pressure sensor — Incorrect pressure signal causes improper system supply.
  Solution: Replace with new air pressure sensor and check connector pins.
• Fault 2: Increased Fuel Consumption
  Root Cause: Inaccurate air pressure reading leads ECU to inject excessive fuel.
  Solution: Install new air pressure sensor and clear engine fault codes.
• Fault 3: Abnormal Exhaust During Operation
  Root Cause: Wrong pressure signal causes air-fuel ratio imbalance.
  Solution: Replace air pressure sensor and inspect mounting gap; clear DTC with diagnostic scanner.
• Fault 4: Machinery Rough Running & Unstable RPM
  Root Cause: Fluctuating sensor signal makes ECU adjust working status frequently.
  Solution: Replace the air pressure sensor before pursuing expensive machinery repairs.
• Fault 5: Sensor Internal Damage from Dust & Vibration
  Root Cause: Long time heavy vibration and dust pollution causes internal chip failure.
  Solution: Replace sensor, clean mounting surface and check for air leakage.
