Answer 1

Hi there,

P1444 is a code for the purge control solenoid valve. This is mounted under the hood on the engine and opens to let the vacuum pull the fuel vapors from the charcoal canister. The solenoid will require testing to make sure it's switching when the ecm tells it to.

The P0325 is a code for the knock sensor. This will not turn on the light and generally will not keep the car from passing inspection. Most of the time replacing it will resolve the code issue.
