JAC and Yue new car exhaust system fault light, what reason? Can you continue to drive?
The best to go to 4S shop to see better
Engine work is not smooth, a direct impact on the car's power and economy, as well as passenger ride comfort, increase vehicle emissions and so on. Therefore, when the vehicle engine instability occurs, to determine the cause of the failure to restore the normal work of the method. Check the steps are as follows: 1, should check the spark plug and sub-cylinder line. Spark plug gap is consistent with the original technical standards, sub-line line resistance is also in line with technical requirements, if not meet the need to adjust or replace. 2, the need for fuel pressure system testing. Check the fuel pressure gauge and the fuel pressure gauge assembly, connecting tubing and oil gauge. Start the engine and make it into the idle operation, fuel gauge reading should be in the range of 270 ~ 320kpa. If the pressure exceeds the technical specifications, you need to replace the fuel pressure regulator and fuel filter. 3, check the cylinder nozzle. So that the engine into the idle operation, respectively, disconnect each nozzle plug to check whether the idle speed changes, if the opening of each cylinder nozzle, idling down basically the same, then the nozzle is working properly. When disconnecting a nozzle, the engine idling and its stability are no change, you need to measure the nozzle nozzle resistance value is 10 to 13, if not meet the standard replacement nozzle. Of course, also need to PGM-FI main relay and plug connection between the wire inspection, plug connection point and the nozzle between the wire is broken, poor connection and other failures.
Not a big problem, you can drive in the car parts in the airbag, ABS, engine failure and so on these safety components of the core can not be sloppy, but the exhaust does not matter
It does not matter, this is the exhaust gas detection sensor problems, you can go to 4S shop with a computer diagnostic device to see which parts of the sensor problems, you can use the detector to reset the next, if the problem still exists which sensor is a problem
