3. Pressure Sensor Troubleshooting & Diagnostic Guide

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

• Fault 1: Engine Power Drop & Weak Acceleration
  Root Cause: Damaged pressure sensor — Incorrect pressure signal causes improper fuel supply.
  Solution: Replace with new 0261230112 pressure sensor and check connector pins.
• Fault 2: Increased Fuel Consumption
  Root Cause: Inaccurate pressure reading leads ECU to inject excessive fuel.
  Solution: Install new 0261230112 pressure sensor and clear engine fault codes.
• Fault 3: Black Smoke Exhaust During Operation
  Root Cause: Wrong pressure signal causes air-fuel ratio imbalance.
  Solution: Replace 0261230112 pressure sensor and inspect mounting gap; clear DTC with diagnostic scanner.
• Fault 4: Engine Rough Idle & Unstable RPM
  Root Cause: Fluctuating sensor signal makes ECU adjust fuel supply frequently.
  Solution: Replace the 0261230112 pressure sensor before pursuing expensive engine repairs.
• Fault 5: Sensor Internal Damage from Oil & Vibration
  Root Cause: Long time heavy vibration and oil pollution causes internal chip failure.
  Solution: Replace sensor, clean mounting surface and check for oil leakage.
