Symptoms of Poor or Faulty Electronic Spark Control
Common symptoms include engine performance issues, engine stalling, vehicle not starting, and engine not having spark.
Modern vehicles are equipped with a variety of electronic sensors and modules to control the various engine functions needed to run the vehicle. One such component is the electronic spark control module, commonly referred to as the ESC module, or ignition module. The ignition module works in conjunction with the computer to synchronize the engine's ignition system for the best performance and efficiency. One of the specific functions of the ESC module is to advance or retard ignition timing depending on operating conditions.
Under heavy load, the module will advance timing to increase power and slow it down at low throttle and cruising speeds to maximize efficiency. The ESC module makes these changes automatically and seamlessly, almost imperceptibly to the driver. Since the ESC module plays an important role in the operation of the engine, any problems with it can cause problems with the vehicle's handling and performance. Usually, a faulty or faulty ESC module will cause several symptoms that can alert the driver to a potential problem that needs to be fixed.
1. Problems with engine operation
One of the first symptoms of a problem with an ignition module is problems with the engine. If the ignition module fails or has any problems, it can lead to vehicle performance issues such as misfiring, hesitation, loss of power, and even reduced fuel consumption.
2. Engine stalls
Another sign of a problematic ESC module is the engine stalling. A faulty module can cause the engine to stop abruptly and be unable to restart. Sometimes the engine can be restarted after a short period of time, usually after the module has cooled down.
3. Car won't start or engine won't spark
Another common symptom of a bad ESC module is no start or no spark. The ESC module is one of the components that directly controls the engine spark, so if it fails, the car can be left without a spark. A car without spark may still start, but will not start or run.
The ESC module is one of the most important components of many modern ignition systems and without it, most vehicles will not function properly. If you suspect your ESC module may have a problem, have your vehicle checked by a professional technician such as AvtoTachki to determine if your vehicle needs an electronic ignition control replacement.
