3. Wiring Harness Sensor Troubleshooting & Diagnostic Guide

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

• Fault 1: Intermittent Signal Loss on Machine Dashboard
  Root Cause: Damaged or broken wiring harness — Engine controller receives unstable signal.
  Solution: Replace with new 20893503 wiring harness sensor and inspect connector pins.
• Fault 2: Random Engine Alarm & Unstable Operation
  Root Cause: Poor wire connection makes engine controller misjudge sensor signal status.
  Solution: Install new 20893503 wiring harness sensor and check wiring connector.
• Fault 3: Engine Electrical Related Fault Code
  Root Cause: Open circuit, short circuit or corroded harness connector.
  Solution: Replace 20893503 wiring harness sensor and clean connector terminals; clear DTC with diagnostic scanner.
• Fault 4: Engine Hard To Start & Rough Idle
  Root Cause: Unstable signal data leads controller to incorrect engine adjustment.
  Solution: Replace the 20893503 wiring harness sensor before pursuing expensive engine repairs.
• Fault 5: Harness Internal Damage from Oil & Vibration
  Root Cause: Long time heavy vibration and oil pollution causes internal wire damage.
  Solution: Replace harness, check oil pipeline and fix wire position properly.
