3. Sensor Bracket Troubleshooting & Diagnostic Guide

If your VOLVO excavator machinery engine system is exhibiting bracket-related failure, consult the diagnostic guide below:

• Fault 1: Sensor Loose & Signal Fluctuation
  Root Cause: Deformed or broken sensor bracket — Sensor position offset causes unstable signal.
  Solution: Replace with new 21304786 sensor bracket and re-fix sensor.
• Fault 2: Engine Intermittent Alarm
  Root Cause: Bracket crack leads to sensor displacement, controller gets wrong signal.
  Solution: Install new 21304786 sensor bracket and check sensor installation status.
• Fault 3: Sensor Physical Damage
  Root Cause: Broken bracket causes sensor collision with surrounding engine parts.
  Solution: Replace 21304786 sensor bracket and inspect sensor condition; clear DTC with diagnostic scanner.
• Fault 4: Engine Rough Idle & Power Drop
  Root Cause: Offset sensor leads to incorrect signal data for engine adjustment.
  Solution: Replace the 21304786 sensor bracket before pursuing expensive engine repairs.
• Fault 5: Bracket Corrosion & Fatigue Fracture
  Root Cause: Long time heavy vibration and oil pollution causes metal fatigue and rust.
  Solution: Replace bracket, clean surrounding oil and tighten fixing bolts properly.
