SOURCE: im getting a P0441 EVAP emission control system

Here is what I could find for your code error as potential causes:
After market parts and accessories nonconforming to the EVAP system specifications.
Damaged, missing or improperly installed fuel filler cap.
Blockage in fuel vapor hoses/tubes (EVAP canister tube, EVAP canister purge outlet tube or EVAP return tube) in EVAP system.
Disconnected or cracked fuel vapor hoses/tubes in EVAP system.
EVAP canister purge valve stuck closed.
Canister vent (CV) solenoid stuck open.
Fuel tank pressure (FTP) sensor malfunction.
EVAP canister leaking.
Fuel vapor control valve tube assembly blocked.
Fuel vapor vent valve assembly blocked.

Obviously the gas cap would be the easiest and cheapest thing to fix.  Just make sure it is put on correctly and tight.  If it is not that, I would have to suggest to take it to a mechanic because the other problems on that list are not really DIY material.  Hopefully it is the gas cap and you can take care of it yourself.  Good luck.

SOURCE: trouble code shows po452 which is the evap

P0452 Evap.Emission System-Pressure Sensor Low Input

The evaporative emission control system prevents hydrocarbon vapors from escaping from the fuel tank into the atmosphere where they could form photochemical smog. Gasoline vapors are collected in the charcoal canister. The Fuel Tank Pressure Sensor (FTPS) is an integral part of the evaporative monitoring system. The PCM monitors the FTPS signal to detect vacuum decay and excess vacuum. The FTPS measures the difference between the air pressure inside the fuel tank and outside air pressure to check the purge control solenoid valve operation and for leak detection in the evaporative emission control system by monitoring pressure and vacuum levels in the fuel tank during the purge control solenoid valve operating cycles.

Code po447 and po453. Likely cause? Thanks, Jim.


code p 0447 refers to evaporative emission (EVAP) system vent control---open circuit ===causes --wiring open circuit--EVAP canister purge valve---ECM
code p 0453 refers to EVAP pressure sensor ---high input===causes --wiring short to positive ---EVAP pressure sensor --ECM

Will this code po447 cause my car to run bad


doubt check the gas cap will fix it, that usually throws a gross evap leak code. that code refers to the vent control circuit, specifically to the connectors at the evap canister behind the passenger wheel. it\'s pretty easy to get to, so get a nice flashlight and check the connector, my bet is that some water (as in the linked post) got in the connector or the connector itself is damaged.

    What is code PO447? How do you fix it?


    PO 447 has to do with the EVAP emissions control circuit. This is what 'sucks' the gas fumes from the gas tank. The first thing to check is the gas cap. Is it tight? Is the seal cracked? If not, the EVAP purge valve may be bad or the rubber hose that goes to it has a leak.
