What are the causes of EPC light on and engine shaking?
1 Answers
epc light on and engine shaking are caused by: 1. Idle switch short circuit or open circuit; 2. Improper installation or adjustment of the throttle position sensor, causing the idle switch not to close when the throttle is fully closed, or the idle switch remains closed when the throttle has a certain opening; 3. Poor contact of the sliding contact of the linear variable resistor, resulting in intermittent interruption of the throttle position sensor output signal during the process of the throttle returning from fully closed to fully open. The maintenance methods for the engine are: 1. Regularly change the oil and filter; 2. Use lubricating oil of appropriate quality grade; 3. Regularly clean the radiator; 4. Regularly clean the air filter, oil filter, and fuel filter; 5. Maintain good crankcase ventilation and clean it regularly; 6. Regularly clean the fuel system.
