Ignition timing is controlled by the electronic control ignition timing system.
The standard reference ignition timing data for the engine
operating conditions are pre-programmed in the memory of the ECM (Engine
Control Module).
The engine operating conditions (speed, load, warm-up
condition, etc.) are detected by the various sensors. Based on these
sensor signals and the ignition timing data, signals to interrupt the
primary current are sent to the ECM.
The ignition coil is activated, and timing is controlled.

Description
Purge Control Solenoid Valve (PCSV) is installed on the surge
tank and controls the passage between the canister and the intake
manifold. It is a solenoid valve and is open when the ECM grounds the
valve control line. When the passage is open (PCSV ON), fuel vapor
stored in th ...
