DTC Detection Logic
This diagnosis detects leaks in the EVAP line between fuel tank and EVAP Canister Purge Volume Control Solenoid Valve, using the negative pressure caused by decrease of fuel temperature in the fuel tank after turning ignition switch OFF.
If ECM judges there are no leaks, the diagnosis will be OK.
- EVAP system has a leak.
- EVAP system does not operate properly.
