What is the detailed explanation of Transit fault lights?
2 Answers
Transit fault lights include: cruise control indicator, vehicle maintenance warning light, ultrasonic reverse assist indicator, blind spot monitoring indicator, powertrain warning light, forward collision warning light, lane keeping indicator, upshift prompt light, fuel gauge/fuel filler cap position, electronic throttle control indicator, transmission overheating warning light, DBC downhill brake control, ABC active body control, air filter replacement warning light, trailer coupler fault light, etc. Reasons for engine fault light illumination: Most car owners have probably experienced this situation - shortly after refueling, the engine fault light on the dashboard comes on. This is usually caused by filling up with poor-quality gasoline at non-standard gas stations, resulting in insufficient combustion of the air-fuel mixture during engine operation. While this doesn't affect driving safety, it may cause some degree of damage to the engine. Reasons for oxygen sensor fault light illumination: Modern vehicles are equipped with two oxygen sensors, one before and one after the three-way catalytic converter. The front oxygen sensor detects the air-fuel ratio under different engine operating conditions, while the ECU adjusts fuel injection quantity and calculates ignition timing based on this signal. The rear sensor mainly monitors the working condition of the three-way catalytic converter. Therefore, if the oxygen sensor is damaged or the sensor connector is faulty or loose, it may cause the air-fuel mixture to become too lean or too rich, triggering the fault light.
I've been driving a Ford Transit for deliveries for several years, and whenever a warning light comes on, I have to check it immediately, otherwise, trouble on the road is inevitable. The engine warning light is the most common, usually indicating sensor failure or excessive emissions, such as a dirty oxygen sensor. The ABS light signals an issue with the anti-lock braking system, possibly due to worn brake pads or wiring faults. When the airbag light flashes, check the seat belt buckle or a loose sensor. The battery light could mean the alternator isn't working or the battery is old—ignore it, and the vehicle will stall. The tire pressure light triggers if pressure is too low or high; just use a gauge to check. During every service, I have the mechanic scan for fault codes, and I regularly clean the air filter to prevent dust from clogging sensors, reducing the chances of lights coming on. Driving with a warning light on isn't just dangerous—it can damage more components, so I always stop to inspect or seek professional help as soon as one lights up.
