Canister Purge Control

- The ECM receives signals emitted from the engine coolant temperature sensor, vehicle speed sensor 2 and crankshaft position sensor to control the purge control solenoid.
Canister purge takes place during operation of the vehicle except under certain conditions (during idle, etc.).
- The purge line is connected to the throttle chamber to purge fuel evaporation gas from the canister according to the amount of intake air.
