P1441 Pontiac Code - EVAP System Flow During Non-Purge Condition
Quick Answer
The Powertrain Control Module (PCM) monitors the amount of vacuum/pressure in the EVAP system by monitoring the fuel tank pressure sensor signal. Common causes include Faulty EVAP canister purge solenoid, Faulty Fuel Tank Pressure (FTP) sensor. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

What are the common symptoms of code P1441 in a Pontiac?
Symptoms may include the check engine light turning on, decreased fuel efficiency, and a faint fuel odor near the vehicle.
What causes code P1441 to appear on a Pontiac?
Common causes include a stuck open purge valve, a faulty EVAP pressure sensor, a damaged or disconnected EVAP hose, or a malfunctioning vent valve.
Can driving with code P1441 damage my Pontiac?
While driving with P1441 may not cause immediate damage, prolonged issues with the EVAP system can lead to increased emissions and potential harm to other components.
How can I diagnose code P1441 in a Pontiac?
Diagnosis typically involves inspecting the purge valve, vent valve, EVAP hoses, and pressure sensor for damage or malfunctions using a scan tool and performing a smoke test.
