How does a GM Electronic spark control module work?
This module is essentially a small computer, and can determine the exact location of the engine knock. The control module can then adjust the timing of the engine to compensate and eliminate the vibration. Often, compensating for an engine knock requires engine timing to be slowed, leading to a temporary reduction in power.
What causes a GM spark control to knock?
Spark Control Causes The Electronic Spark Control, also called the Knock Sensor, is an electronic device built by General Motors to help regulate the timing inside of the engine. When combustion inside the engine does not fire properly, a “spark knock” or abnormal vibration can occur.
Can a bad ESC module cause no spark?
Another common symptom of a faulty ESC module is a no start, or no spark condition. The ESC module is one of the components that directly controls engine spark, so if it fails, it can leave the vehicle without spark.
What are the symptoms of a bad spark control?
Car not starting or engine not sparking. Another common symptom of a faulty ESC module is a no start, or no spark condition. The ESC module is one of the components that directly controls engine spark, so if it fails, it can leave the vehicle without spark.

Why does my electronic spark control stop working?
As an engine ages, its timing can degrade, leading to knocks. Outside factors such as the humidity or altitude where the engine is operating can also cause timing issues. Electronic Spark Control compensates for these occurrences.
How does an electronic ignition system work in a car?
Here the work starts electronically. It is used to ON and OFF the primary current. The ignition control module performs the same operation as that contact point performs in another ignition system. It manages the dwell period (remains in a given state) on its own.
How does the electronic spark control system work?
There are three basic components of the Electronic Spark Control (ESC) system. The Electronic Spark Control (ESC) sensor detects the presence (or absence) and intensity of the detonation by the vibration characteristics of the engine. The output is an electrical signal that goes to the controller.
What does ESC stand for in spark control?
In addition, the SFI system incorporates a new Computer Controlled Coil Ignition system that uses an electronic coil module that replaces the conventional distributor and coil used on most engines. An electronic spark control (ESC) is used to adjust the spark timing. ESC – Electronic Spark Control Testing
What happens when the spark control module fails?
During different driving conditions, like acceleration and cruising speeds, the spark control module makes small changes to the spark timing to assure your engine runs at its best. When an ignition module fails, your engine may struggle to start, or may misfire or stall.
What should ignition timing be for electronic spark control?
Basic ignition timing is critical to the proper operation of the Electronic Spark Control (ESC) system. Always follow the Vehicle Emission Control Information (VECI) label procedures when adjusting ignition timing. Some engines will incorporate a magnetic timing probe hole for use with special electronic timing equipment.
