What are the reasons for the engine fault light in Shandeka trucks?
1 Answers
The reasons for the engine fault light in Shandeka trucks may include turbocharging issues, unqualified exhaust emissions, clogged fuel injectors, throttle position sensor problems, and in some vehicles, transmission system faults are also indicated through the engine fault light. The specific reasons are as follows: Sensor issues: Sensors include coolant temperature, crankshaft position, air flow, intake air temperature, oxygen sensors, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which will cause the engine fault light to illuminate. Turbocharging issues: Intake turbocharging pipelines and turbochargers can also cause the engine fault light to illuminate. The most common issue is turbocharger damage, accompanied by symptoms such as oil leaks, excessive oil consumption, reduced power, metal noises, and blue or black smoke from the exhaust pipe. Exhaust issues: Rear oxygen sensors, catalytic converters, exhaust camshafts, and bearings. The most common issue is catalytic converter failure causing the engine fault light to illuminate. Factors such as using leaded gasoline, lead or silicon-based lubricant additives, physical damage to the catalytic converter, and engine fuel system faults can easily lead to catalytic converter failure. Anti-theft system: If the vehicle's electronic anti-theft system malfunctions or the anti-theft controller does not match the engine electronic controller, the anti-theft system can also cause the engine to malfunction, along with the engine fault light illuminating. Solutions: If this fault occurs, the vehicle should not be driven: Check if the vehicle's coolant is low, if the engine oil needs to be replaced or is low, clean the throttle, clean the intake tract, check if the spark plugs are functioning properly, and if the ignition coils are normal. The vehicle should not be driven with this fault.
