1 of the fuel consumption of high speed slow is what reason?

According to Carol solar term door body was informed that there are many factors that lead to high oil consumption, such as driving habits (emergency refueling, slam the brakes, coasting, speed and gear does not match and so on), the tire pressure is too low, the addition of inferior oil, ignition system fault and the fault of electronic control system, the fault will increase vehicle fuel oil consumption. Secondly, if the vehicle isnot on time maintained, such as not timely replacement air filter, gas filter, spark plugand clutch plates etc. these components, the problem such as this can also lead toincreased fuel consumption.

Another is the product of fault carbon and electric control system, such as the solar term door body, idle valve and injector carbon, oxygen sensor, air flow meter and a water temperature sensor signal misalignment and so on, these will affect the vehiclefuel consumption, high oil consumption needs to conduct a comprehensive inspection.

For you this car, fuel consumption and high key check each sensor signal is normal,check whether the parts of carbon deposition seriously, check whether there is a problem to add oil etc..

The 2 engine abnormal indication light do?

Engine fault light. Cairo solar term door body representation or engine does exist fault problem. Need to repair shop inspection. Or is the program problems. To store recomputer programming.

4 how to check the brake fluid is leaking?

Let the engine idling, and the transmission shaft in a "neutral" position, the brake pedal, pedal force and remain unchanged. If in force under the condition of invariable,pedal slowly whereabouts, then hydraulic braking system may have leaks.

1 check the liquid storage device of braking general pump the liquid level in thenormal position, the friction lining wear will lead to liquid level decreased slightly. If the reservoir level reduce the anomaly, will cause the brake warning lamp lit, Carol throttle body called internal or external leakage may this shows that the hydraulic system.

2 check the brake pipe and brake hose connections for leaks, such as the existence of leakage, check the fastener torque, or replace the oil pipe or hose.

3 check the connection brake element is damaged, if necessary to reinstall or replace connection brake components. Check the calipers and wheel cylinder protection cover is leakage, such as leakage, when necessary to reinstall or replacement of these components.
