1. What are the reasons for the slow increase in fuel consumption?
There are many factors that lead to excessive fuel consumption, such as driving habits (emergency fueling, sudden braking, neutral coasting, speed inconsistent with gears), tire pressure is too low, poor quality oils are added, ignition system failures, and electronic control system failures. These failures will increase the vehicle's fuel consumption. Secondly, if the vehicle is not maintained on time, for example, if the air filter, gasoline filter, spark plug, clutch plate and other components are not replaced in time, fuel consumption will increase.
Then there are the failures of carbon deposition and electronic control systems, such as the carbon deposits of the throttle body, idle valves and fuel injectors, and the misalignment of oxygen sensors, air flow meters, and water temperature sensors, all of which affect the vehicle's fuel consumption. Excessive fuel consumption requires a thorough inspection. For your vehicle, the key to checking fuel consumption is to check if the signal of each sensor is normal, check whether the carbon components are serious or not, and check whether there is any problem with the added oil.
2. Will the lack of power in the car battery lead to insufficient power?
No, it just can't get a car, but it can happen if there is a short circuit inside the battery.
3, engine abnormal indicator light has been how to do?
The engine fault light is on. It is true that there is a fault in the engine. Need to go to the store to detect maintenance. Or is it a problem with the program? Go to the store to reprogram computer.
4. How to check if brake fluid leaks?
Let the engine idle, and the drive shaft in the "neutral" position, step on the brake pedal, and keep the foot pedal force unchanged. If the pedal is slowly falling when the force is not changed, the hydraulic brake system may be leaking. Perform the following visual inspection to confirm whether there is a leak.
1. Check the fluid level in the brake master cylinder reservoir. Normal wear of the friction lining will cause a slight drop in the liquid level in the reservoir. If the reservoir level drops abnormally, it will cause the brake warning light to illuminate, indicating that the hydraulic system may have internal or external leakage.
2. Check for leaks at the brake pipe and brake hose connections. If there is a leak, check the fastener torque or replace the hose or hose.
3. Inspect the brake-attached components for damage and reinstall or replace the brake-attached components if necessary. Check the caliper and wheel cylinder cover for leaks, if there is a leak, reinstall or replace these components if necessary.
