Hello and welcome to Just answer.com, Super mechanic here. About your vehicle.

 

There not any recall for that. There is a test for it though.

 

APPLIES TO: ALL

 

SERVICE TIP:

 

Evaporative Emission Control System Incorrect Purge Flow

 

SYSTEM OPERATION

DTC P0441 sets when the negative fuel tank pressure is below -2.0 kPa (-0.6 inHg) during normal driving. During driving, fuel tank pressure is monitored continuously by the OBD-II system EVAP monitor as the PCM closes the purge and vent solenoids.

 

 

 

 

The most likely reason for DTC P0441 to set during the EVAP monitor is due to a blockage or restriction on the vent side of the system (in a hose, vent valve, or frame where a hose vents). Since the fuel tank pressure sensor is continuously monitored, whenever the fuel tank pressure sensor reads below -2 kPa (-0 .6 inHg), DTC P0441 will set.

 

 

Here is a link to the test procedure. However, dont' forget to come back and hit the accept button, that is the only way we get paid, thanks
