Code P2450 Description
The system may not purge the carbon canister under idle conditions. The vehicle may need to be driven for the system to operate, an actuator test may be used to operate the solenoid valve with a scan tool.
Due to the presence of harmful hydrocarbons within the system manufacturers have to closely monitor the system, in some markets. This is achieved by the addition of certain hardware to measure system pressure and gas flow. The engine control module can monitor the system for leaks (both large and small) and for excessive or insufficient flow. This allows the technician access to more information relating to the fault and provides a better chance of an accurate diagnosis.
