The Sparkplug Firing The voltage demand on the ignition coil by the sparkplug varies with load on the engine. It may require only 1,000 volts for it to ignite when the engine is idling and cylinder pressure is low, but then need 20,000 volts to climb a hill under full throttle. This posed a dilemma for the ignition designer. Disconnect the ignition coil wire from the distributor and install the spark tester to the wire and ground the tester to the engine. Crank the engine for a few seconds. If there’s spark, the problem is with the distributor cap (carbon tracks or wear) or rotor. Consult your vehicle repair manual, if necessary.

How to test ignition control module chevy. The electronic ignition control module is a solid state switch «On/Off» for the ignition system. The module receives a signal from a sensor inside the distributor. The signal is then used to ignite the ignition coil, which generates the energy for the spark plugs. The primary circuit includes the battery, ignition switch, a control module (switching device), and the primary winding of the ignition coil. The secondary circuit includes the secondary winding of the ignition coil, spark plugs, and on some vehicles a distributor and/or spark plug wires. The ignition coil transforms the 12 volts from the.

When a P0687 code is stored, it typically means that a high voltage condition has been detected by the powertrain control module (PCM) or one of the other controllers, in the circuit which powers up the PCM or the circuit by which the other controllers monitor PCM power supply voltage. Most OBD-II equipped vehicles use a contact relay to supply. The control module enters this mode when the battery voltage is less than 13.2 volts for 45 minutes. Once in this mode, the generator battery control module will set a targeted output voltage between 13.9 to 15.5 volts for 5 minutes. The control module will then determine which mode to enter depending on voltage requirements. RVC Mode.

The other circuit sends full battery voltage to the coil. The only time this circuit is used is during cranking. ... is that the control module can handle much higher primary voltage than the mechanical points. Voltage can even be stepped up before sending it to the coil, so the coil can create a much hotter spark, on the order of 50,000 volts.
