Leak Detection Valve: Description and Operation

CANISTER CLOSE VALVE (CCV)




DESCRIPTION
The evaporative emission control system prevents hydrocarbon (HC) vapors from the fuel tank from escaping into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Canister Close Valve (CCV) closes off the air inlet into the canister for leak detection of the evaporative emission system. When the engine purges the HC vapors from the canister, the clean air comes into the canister through the canister air-filter and the CCV.

SPECIFICATION
Item Specification
Coil Resistance 23.0 - 26.0 Ohms at 20 degrees C (68 degrees F)
