hey does anyone know what p1441 is. thats the code my computer is throwing out.

i know u have a v6, but the code seems to be universal for GM engines from what ive read

 

That's EVAP system purge during non-purge

Translated into normal language, you're evap system is doing it's job (letting pressure out of the fuel system) when it's not supposed to be.

 

Awh, Specter with the quickdraw[&o]

You may have won this one, so we're even now. haha

 

so a fuel cap

 

No, the fuel cap is made to only let air in, so when you use gas the tank can equalize the pressure. The EVAP system is used to release extra pressure out of the fuel system when the gas gets heated up and turns into vapor.

 

so what would i need to fix

 

I haven't had the issue, so I haven't personally dug around in it, but you would have to find the sensor/faulty part that is causing the code.

aaaannnnddd...cue z28pete to chime in and let us know what to look for!! (pete knows all the sensors and codes and such, he's pretty much the man...)

 

I actually think pete may be an internet based AI database bot for chevy technical issues [>:]just when im starting to think I know a thing or two about these cars he pulls something from the nether realm to answer a question

 

Basically as 95slvrZ28 said.

But, being that you really wanted to know, and are waiting with bated breath. LOL

Normal state: The fuel tank fumes are vented into theEVAP canister (EVAP purge valve OFF, EVAP vent valve OFF).
Purge State: The EVAP canister is purged when a certain fuel tank pressure is reached, by allowing engine vacuum to suck the fumes out of the canister and into the engine for burning. (EVAP purge valve ON, EVAP vent valve OFF)

P1441: The PCMseals the EVAP system by commanding the EVAP purge valve OFF, and the EVAP vent valve ON. The PCM monitors the fuel tank pressure (FTP) sensor in order to determine if a vacuum is being drawn on the EVAP system. If the vacuum in the EVAP system is more than a predetermined value within a predetermined time, DTC P1441 will set. In other words, the PCM sees vacuum in the tank instead ofa slight pressure created by the fumes. (possible bad or stuck purge valve, among other things)


Possible causes:
Bad FTP sensor (Fuel Tank Pressure), on top of fuel tank near fuel gage sensor
EVAP canister purge valve, under hood
EVAP purge valve solenoid, under hood
Wiring problems
