SOURCE: 2003 chevy 1500 has a code that says large evap

"Where" to find the leak is in your evaporative emmissions system. Most of the time, a good visual inspection will turn up the culprit. First, check the fuel cap. Look at the rubber O-Ring that seals it against the fuel fill tube. If it is cracked or looks like it is crushed down, replace your fuel cap. If that all looks OK, then you can check the rest of the system for obvious cracks, or leaks. Start with the Evap Purge line. You can identify this in the engine compartment as a plastic vacuum line about 5/16" in diameter and it has a service port on it with a green cap. Check the plastic line for cracks. Then check the rubber components that connect to this line on both ends. One end will go into the Purge Solenoid and the other will go into a steel line that runs along the frame rail under the vehicle. Follow this steel line to where it goes and inspect all connecting hoses, tanks, etc. there will also be rubber hoses at the fuel tank area and some that connect to the fuel fill tube. Check all of these for any visual signs of damage or leaks. Also check for badly corroded metal parts - especially near the fuel fill tube. Sometimes the metal tubes get rusted through and cause leaks.

If a thorough visual inpection does not lead you to a suspect, then the system will have to be "smoke-tested". This is where the system is filled with smoke under a slight amount of pressure so the leak can be seen where the smoke comes out.

SOURCE: i have 2000 chevy impala 3.4 engine i have check

This indicates a fuel vapor leak in the EVAP control system. It means a very small leak has been detected. In fact, the leak can be from a hole as small as 0.04" in diameter. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.
code P0442 most likely means one or more of the following has happened:

  • A loose or improperly affixed gas cap
  • A non-conforming gas cap (i.e. not factory/original brand)
  • A small leak/hole in a fuel vapor hose/tube
  • Other small leak in EVAP system
  • Faulty vent o-ring seal
With a P0442, the most common repair is to:
  • Remove and reinstall the gas cap, clear the codes, and drive for a day and see if the codes come back.
  • Otherwise, replace the gas cap, or
  • Inspect the EVAP system for cuts/holes in tubes/hoses

SOURCE: 2003 chevy impala ls starts then stalls

I have replaced the radiator in my 2003 Chevrolet Impala LS. The car started running hot and shut down. Took it to a radiator shop and found a crack in the radiator. I have replaced 2 thermostats in the car already. I noticed water running from under my car today and it seems it was coming back out of the overflow. I am stumped as to what is going on with this car.

2003 Chevy Silverado 1500 Error Codes


P0135 is a bad 02 sensor
P0442 is a evap problem
P0449 is a vent solenoid

i would check the vent solenoid first its a 4ws fuse under the hood in the fuse box make sure you have power to it you should have power at all times the ground comes from the pcm i think if you fix this everything else will work they are all computer controled
