What Causes the Engine to Suddenly Stall After the Malfunction Indicator Light Comes On?
1 Answers
The reasons for the engine suddenly stalling after the malfunction indicator light comes on are as follows: 1. The owner did not refuel in time, leading to fuel exhaustion during driving, resulting in insufficient fuel and low fuel pressure, which triggers the engine malfunction light and prevents the vehicle from starting. 2. Sensor issues, such as problems with the camshaft position sensor, oxygen sensor, crankshaft position sensor, intake pressure sensor, or air flow sensor. In such cases, try disconnecting the battery negative terminal for ten minutes and then attempt to start the vehicle. If it starts, it is still necessary to have it inspected and repaired at a service center as soon as possible. 3. Loose fuses, poor contact due to excessive gaps in wiring connectors, or damp wiring that causes disconnection or short circuits due to road bumps, leading to the malfunction light illuminating and the vehicle stalling. 4. Poor-quality fuel causing cylinder misfires, or carbon buildup in the throttle body, fuel injectors, or internal engine passages, or issues with the fuel system such as a damaged fuel pump, clogged fuel filter, or obstructed fuel lines. 5. Abnormal coolant temperature or insufficient engine oil leading to engine seizure, which is a severe condition. 6. Poor road conditions, which may cause the undercarriage to scrape, leading to fuel line leaks or wiring damage.
