What is the reason for the fault light on the Maxus T60 and lack of power when accelerating?

The reasons for the fault light on the Maxus T60 and lack of power when accelerating include poor ignition system performance, fuel system malfunction, and clogged three-way catalytic converter. Poor ignition system performance: For example, aging ignition coils or spark plugs that have not been replaced for a long time can result in insufficient ignition energy, poor combustion, weak engine acceleration, and the engine fault light turning on. Replacing the ignition system components can resolve this issue. Fuel system malfunction: A malfunction in the fuel system can cause low pressure and insufficient fuel injection, leading to weak engine acceleration. It is necessary to inspect and replace the fuel filter and fuel pump. Clogged three-way catalytic converter: If the quality of the fuel used is poor, it can affect the lifespan of the three-way catalytic converter in the exhaust system. Once the three-way catalytic converter is clogged, the car will experience weak acceleration and increased fuel consumption. Checking whether the three-way catalytic converter is functioning properly and cleaning it can restore normal operation.
When driving my Maxus T60, I encountered a similar issue - the moment the warning light came on, the acceleration felt sluggish with no power at all. This is usually caused by a fuel system blockage, such as insufficient fuel pump pressure or clogged injectors preventing fuel from reaching the engine, naturally resulting in poor acceleration. It could also be related to a dirty air filter restricting airflow and starving the engine of sufficient air. Additionally, symptoms like this may occur if the turbocharger is stuck or has an air leak. I recommend first checking whether the fuel pump and filter are functioning properly, inspecting the fuel pressure gauge, and taking a quick look at the air system for carbon buildup. If the problem persists, it's best not to force the vehicle to run. Instead, take it to a professional repair shop for OBD diagnostic code reading - usually the culprit can be identified within minutes. This prevents travel delays or more serious issues like engine overheating or unexpected stalling risks.
My Maxus T60 also had the issue of the malfunction light coming on and lack of power when accelerating. When pressing the gas pedal, the car felt like it was dragging a heavy load, with very slow acceleration. Common causes include worn spark plugs or faulty ignition coils, which lead to poor ignition and prevent the engine from running smoothly; or an aging fuel pump that can't supply enough fuel. I also suspect it might be due to excessive carbon buildup in the throttle body, affecting throttle response. Don't underestimate these details—last time I neglected them, the repair costs doubled later. I recommend checking the fuel pump and spark plugs first. Replacing them yourself isn't too difficult, but be careful not to damage the electrical wiring. If you can't fix it yourself, take it to the 4S shop immediately for diagnosis—they can scan the code with their equipment to identify the issue. Also, develop the habit of gentle acceleration and regular maintenance to prevent such problems in the future.
