- Faulty fuel level sensor: The fuel level sensor is responsible for sending the fuel level information to the instrument cluster. If the sensor is faulty, it may be providing incorrect readings, causing the gas light to come on even when there is still fuel in the tank.
- Damaged or loose wiring: The wiring that connects the fuel level sensor to the instrument cluster may be damaged or loose, disrupting the signal and causing the gas light to come on.
- Faulty fuel pump: The fuel pump is responsible for delivering fuel from the tank to the engine. If the fuel pump is faulty, it may not be able to provide enough fuel, causing the engine to stall and the gas light to come on.
- Clogged fuel filter: The fuel filter removes dirt and debris from the fuel, ensuring that clean fuel is delivered to the engine. If the fuel filter is clogged, it can restrict fuel flow, causing the engine to run lean and the gas light to come on.
As for the "service engine" light, it can be triggered by various issues. Some common causes include:
- Oxygen sensor problems: The oxygen sensor monitors the amount of oxygen in the exhaust gases and helps control the air-fuel mixture. A faulty oxygen sensor can cause the engine to run rich or lean, triggering the "service engine" light.
- Faulty spark plugs or wires: Worn-out or damaged spark plugs or spark plug wires can cause misfires, affecting engine performance and illuminating the "service engine" light.
- Catalytic converter issues: The catalytic converter helps reduce harmful emissions from the exhaust gases. A faulty or clogged catalytic converter can restrict exhaust flow and cause the "service engine" light to come on.
- EVAP system problems: The EVAP (Evaporative Emissions Control) system prevents fuel vapors from escaping into the atmosphere. Leaks or other issues in the EVAP system can trigger the "service engine" light.
It's essential to have both the gas light and "service engine" light issues diagnosed and addressed promptly to ensure proper engine performance, fuel efficiency, and emissions compliance. We recommend taking your vehicle to a reputable mechanic or an authorized Ford dealership for a comprehensive diagnosis and repair.
