🔧 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:
- Faulty Fuel Volume Control Valve (FVCM).
- Damaged Wiring:
- Open circuit, short circuit, or exposed wires.
- Corroded connectors, bent/broken pins.
- Poor Electrical Connection to the valve circuit.
- Fuel Pump Failure (if the valve is integrated and not serviceable).
🔧 Repair Steps:
- Visual Inspection:
- Check the FVCM valve wiring harness and connectors.
- Look for corrosion, physical damage, or stripped wires.
- 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).
- Check Power and Ground:
- Use a Land Rover electrical diagram to test voltage and continuity.
- 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).
