P116F LAND-ROVER – Fuel volume control valve command has exceeded control limits

🔧 Land Rover P116F Code: Diagnosis and Solutions


🚨 Common Symptoms:

  • 🚨 Check Engine Light on (or early warning).
  • 🛑 Performance Issues: Rough idle, loss of power, hard starting.
  • Faulty Fuel Regulation (irregular flow).

⚠️ Possible Causes:

  1. Faulty Fuel Volume Control Valve (FVCM).
  2. Damaged Wiring:
    • Open circuit, short circuit, or exposed wires.
    • Corroded connectors, bent/broken pins.
  3. Poor Electrical Connection to the valve circuit.
  4. Fuel Pump Failure (if the valve is integrated and not serviceable).

🔧 Repair Steps:

  1. Visual Inspection:
    • Check the FVCM valve wiring harness and connectors.
    • Look for corrosion, physical damage, or stripped wires.
  2. Resistance Test:
    • Disconnect the valve and measure its resistance with a multimeter.
    • Normal Values: Between 1.5 and 15 Ω.
    • If out of range → Replace the fuel pump (the valve is not serviceable alone).
  3. Check Power and Ground:
    • Use a Land Rover electrical diagram to test voltage and continuity.
  4. Clean Connectors:
    • Use electrical contact cleaner spray to remove corrosion.

📌 P116F Code Meaning:

  • Description: “Fuel Volume Control Valve Circuit Malfunction”.
  • Note:
    🔍 On Land Rovers, the FVCM valve is often integrated into the fuel pump → Complete replacement required if faulty.

🚨 Key Points to Remember:

  • Do not replace the fuel pump without testing the valve resistance and checking the wiring.
  • A recurring P116F code may indicate a PCM problem (to be diagnosed with a specific Land Rover tool, such as SDD or IIDTool).
  • Always consult official technical data for your model (e.g., Discovery, Range Rover).
