Why does the car not move when the engine yellow light is on?

The reason why the car does not move when the engine yellow light is on is due to the engine malfunction indicator light. The yellow engine malfunction light indicates that there is a fault in the engine. Here are the possible reasons for the engine malfunction light to turn on: Excessive carbon deposits: Using poor-quality gasoline or having excessive carbon deposits in the engine can lead to poor combustion conditions, which may trigger the malfunction light. In such cases, it is necessary to promptly inspect the engine and seek maintenance at a nearby vehicle repair shop. Oxygen sensor malfunction: This type of fault usually causes the engine malfunction light to turn yellow, but it does not affect normal driving. After driving, remember to check the reason for the engine malfunction light being on.
I've encountered similar situations several times where the engine yellow light comes on and the car just stalls, which usually indicates an acute issue with the engine or transmission system. Common causes include sensor errors, such as a faulty crankshaft or camshaft position sensor, causing the ECU to automatically lock the vehicle to prevent damage. It could also be a fuel pump failure, cutting off fuel supply to the engine, or worn clutch plates slipping in the transmission. I recommend turning on the hazard lights and pulling over immediately—don’t force it to drive, or you might end up with a ruined transmission and much higher repair costs. Do a quick check for fluid leaks or unusual smells, but avoid tampering with components, as it could worsen the problem. A professional repair shop can connect a diagnostic tool to read the trouble codes and pinpoint the issue accurately—for example, replacing a sensor might cost just a few bucks, whereas ignoring it could lead to a major repair costing thousands. Regular oil changes and transmission maintenance can significantly reduce the chances of such incidents.
