Buick Grandview engine trouble light on how to do

Engine malfunction light is on because of internal engine failure or bad combustion, Buick Grandview engine self-diagnostic system works on the same principle as most fuel vehicles.

If some of the engine's electrical components, wiring, or some sensors collected parameter indicators beyond a reasonable range, will cause the engine to report a fault code, and depending on the importance of the fault code is different, it will be displayed in the instrument in the form of a fault light.

One, the engine electrical failure: this type of failure includes the damage of some sensors, such as: air flow meter, throttle idle motor, intake pressure sensor, oxygen sensor, ignition coil, spark plugs, water temperature sensor, crankshaft position sensor or camshaft position sensor.

Also included are some control sheets or actuators, such as engine computers, ignition computers, fuel pumps, camshaft adjustment solenoids, etc. In addition to these electrical components, the failure may also be caused by the wires between these components.

Two, engine mechanical failure caused by: for example, changes in fuel quality, the use of some additives more fuel, or intake tract, throttle or spark plugs are covered by carbon deposits, as well as air leakage in the intake tract is lower than the standard value will also produce the corresponding fault code, and in severe cases, will also be in the instrumentation in the report engine fault light.

As one of the most successful strategic models of the Buick brand, the Grand Touring is favored by users for its trendy, sporty and technological product image and comprehensive technical strength.

Buick Grand Touring brings together GM's global advanced technologies, and while inheriting its traditional strengths, it also addresses the ever-increasing needs of consumers in the new era by bringing new driving values to the market with innovative product strengths, and realizing a new evolution of dynamic style, driving quality, and technological attributes.
