What does the fault code 523004/15 mean?
1 Answers
The fault code 523004/15 indicates the following: It means there is excessive carbon buildup inside the engine throttle of the vehicle, and the engine throttle needs to be cleaned. Below are the hazards caused by carbon buildup: 1. Decreased engine power: After carbon deposits form inside the engine, the engine's power will decrease. When driving, you may feel that the car is not as powerful as before, with a sensation that it won't move unless you press the accelerator, leading to a decline in both engine performance and fuel efficiency. Not only does it make the car harder to drive and more fuel-consuming, but it also significantly affects vehicle emissions. 2. Exhaust valve blockage: Carbon buildup in the engine's intake and exhaust areas, especially around the exhaust valve, can easily cause "secondary valve" issues. This is because the carbon deposits on the exhaust valve can prevent it from dissipating heat. Although the exhaust valve is treated with special processes, excessive carbon buildup and high temperatures without proper heat dissipation can still cause problems. 3. Cylinder scuffing: Carbon deposits on the piston head can easily form multiple ignition points during engine combustion, leading to incomplete combustion and knocking in the cylinder, along with a decrease in engine power. In severe cases, it may cause cylinder scuffing. 4. Fuel injector clogging: Carbon buildup in the cylinders of direct-injection engines can easily lead to fuel injector clogging, causing engine shaking and poor acceleration.
