What is the reason for the malfunction light of Toyota Jitter Engine?

The reason why the malfunction light of Toyota Jitter Engine in Pacific Auto Network is on is: 1, and the engine mixture burns badly; 2. Abnormal fuel supply pressure; 3, spark plug electrode gap wear; 4. Ignition coil failure; 5. The rubber parts of the starting bracket or gearbox bracket are aging; 6. The throttle is blocked.

The engine fault light may be a false fault or a true fault. False fault gives fault code, but it works normally. It may be that the operation at a certain time is beyond the control of the computer. The fault code fed back by the computer can be eliminated first, and then we will see if the fault code will jump. The real fault is when there is no obvious fault in the engine. According to the computer detection information and further inspection, it is found that there is a certain fault, which does not affect the normal driving or has little impact, and needs to be found and solved in time.

Replace the oil and oil filter regularly: When the oil passes through the pores of the oil filter, solid particles and sticky substances in the oil will accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element smoothly, the filter element will burst or the safety valve will open, and then the dirt will be brought back to the lubrication part through the bypass valve, which will accelerate the engine wear and aggravate the internal pollution.

Keep the crankcase well ventilated. Contaminants in the air will deposit around the positive crankcase ventilation valve, which may block the valve. If the PCV valve is blocked, the polluted gas will flow back into the air filter, and the polluted filter element will reduce the filtering capacity. The inhaled mixture is too dirty, which will further pollute the crankcase, lead to increased fuel consumption, increased engine wear and even damage the engine.

Regularly clean the crankcase During the engine operation, high-pressure unburned gas, acid, moisture, sulfur and nitrogen oxides in the combustion chamber enter the crankcase through the gap between the piston ring and the cylinder wall, and mix with the metal powder produced by the wear of parts to form sludge. When the amount is small, it will be suspended in the engine oil, and when the amount is large, it will be separated from the engine oil, blocking the filter and oil hole, causing engine lubrication difficulties and wear.

In the process of supplying fuel to the combustion chamber through the fuel passage, colloids and carbon deposits will inevitably form in the fuel passage, carburetor, fuel injector and combustion chamber, which will interfere with the fuel flow, destroy the normal air-fuel ratio, cause poor fuel atomization, and cause engine jitter, explosive vibration, unstable idle speed and poor acceleration.
