What is a spark control on a car?
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.
How does a spark control module work?
The electronic spark control module (ESC) is one of many components in your ignition system. Working alongside your distributor and ignition control module, the electronic spark control module varies ignition depending on many things like engine load. It signals the distributor to advance or retard timing.
What does the electronic spark control module do?
One of these components is the electronic spark control module, commonly referred to as the ESC module, or the ignition module. The ignition module works together with the computer to time 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 the timing…
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
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 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.
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.
Where is the electronic spark control module?
On your year vehicle, the Electronic Spark Control (ESC) is an internal part of the Engine Control Module, located behind the glovebox. Earlier years had a seperate module located on the MAP sensor bracket, but on yours, it was moved to inside the ECM and therefore is not servicable seperately.
What does an ignition control module actually do?
An ignition control module is a component that can regulate spark generation in many internal combustion engines. The main purpose of the ignition module is typically to open or close a ground circuit to the primary winding inside the ignition coil. When this occurs, the coil can generate sufficient voltage to fire a spark plug.
