General Description

The Evaporative system monitoring is made by using Natural Vacuum Leak Detection (NVLD).
The leak detection is made by using two components.
The "NVLD Sensor module" which incorporates the NVLD pressure switch and temperature sensor.
And the canister purge valve which is used as actuator to create vacuum in the tank when the engine is running.

DTC Description

P2027 is set when the communication line between NVLD and PCM shorts to battery.
