What caused the LaCrosse engine fault light to light up?
The causes of these failures can be divided into the following two categories:
1. Engine electrical fault: This kind of fault includes the damage of some sensors, such as air flow meter, throttle idling motor, intake pressure sensor, oxygen sensor, ignition coil, spark plug, water temperature sensor, crankshaft position sensor or camshaft position sensor, etc. It also includes some control units or actuators, such as engine computer, ignition computer, fuel pump, camshaft adjustment solenoid valve and so on. In addition to these electrical components, the wires between these components may also cause faults.
Second, the causes of engine mechanical failure: for example, the change of fuel quality, the use of some fuel with more additives, or carbon deposition in the air intake, throttle or spark plug, and the air leakage at the air intake is lower than the standard value, will also produce corresponding fault codes. In severe cases, the engine fault light will be reported in the instrument.
In any case, when the engine fault light is on, first look at whether it is a red or yellow warning light. If it is a yellow warning light, please send it to the repair shop for repair as soon as possible. If it is a red fault light, it is not recommended to start the vehicle, so you can only ask for help. Million car purchase subsidy
