    Hello. I bought a 1999 Buick Century seadn. the service check light is on with a P1441 code. I replaced the gas cap as the other was very well worn. I had a friend clear the code. After two days, the light is back on with the same code read. Is there a fix-it to this, or will I have to bite the bullet at a shop? Please message back. RJ in Eureka, CA

Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
Inspect the downstream heated oxygen sensor (HO2), replace if necessary
Replace the catalytic converter

P1441 code on2001 740il

2001 bmw 740iL with code p1441 is the leakage diagnostic pump, you will need to check the connection to the pump and also test the evap system for any leaks, you may have a leak in the system, may be a loose gas cap or a line leaking, this system is for the fuel vapors, there are lines that run from the fuel tank to engine and is filtered into a canister and theres valves and leakage pump in lines, a smoke machine would be needed along with a scan tool to check valves and get readings from can check the gas cap and look around for broken lines. good day

I have an 2003 chevy venture and the engine light came on. the auto store told me to google search p1441. What is the problem and how to fix it

P1441 code indicates an EVAP system problem the most likely cause is your charchoal canister needs to be service or you may have a vaccuum leak to it or from it. usually an easy fix first start by tracing the vaccuum lines running to and from it for any broken or cracked lines and replace as needed. If this is ok you can replace the filter in the canister and or just go to the wreckers and replace the whole canister. Or the best would be to replace it with a brand new one from an auto parts store that way you can be sure it will not be a bad one. Be sure to reconnect the vaaccuum lines correctly in the same place you removed them as this can effect vehicle emmissions and produce more codes and cause your vehicle to fail emmissions test.

Imisions test comes back with, code P1441 ?

P1441 is a EVAP code, small leak I thinking.

P1441 Evaporative Emission (EVAP) System Flow During Non-Purge

Now for the fix: the ECM uses a pressure sensor to watch the system and see that there are no leaks. If it sees a leak via the pressure sensor, it sets this code. The ECM wants to see the pressure sensor voltage drop down, indicating that there is vacuum on the system, and it wants it to be able to hold this vacuum for at least 30 seconds. If this does not happen, it will set a code. As a note, the vent solenoid is the most common failure on these systems.

Hope helps (remember to rate and comment this).

Since it is a 1996, you probably have high miles on it.
Most cars after 100,000 miles or so are automatically set to have the check engine light come on.
