• Engine System Protection: Reliable speed signal helps ECU optimize fuel supply and protect engine from overspeed.

3. Speed Sensor Troubleshooting & Diagnostic Guide

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

• Fault 1: Engine Cannot Start or Hard Start
  Root Cause: Damaged speed sensor — No speed signal so ECU cannot trigger fuel injection.
  Solution: Replace with new 0118-2850 speed sensor and check connector pins.
• Fault 2: Engine Sudden Power Cut During Operation
  Root Cause: Intermittent signal loss caused by sensor aging or loose connector.
  Solution: Install new 0118-2850 speed sensor and clear engine fault codes.
• Fault 3: Engine Overspeed Alarm Triggered
  Root Cause: Inaccurate speed reading leads to wrong judgement of engine rotation.
  Solution: Replace 0118-2850 speed 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 0118-2850 speed 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.
