How can i stop my security light from coming on when i start my 2004 3.4 liter chevy impala ?

Hi Glenn, did you by chance replace your PCM with a used computer? If so you will need to have it reflashed, If not sounds to me like the Passkey security needs to be relearned. Also wondering why you replaced PCM after replacing EGR valve, Please if you can give me some more info on your veh. Body control module controls security so something is not right. Please get back to me, Thanks Randy.

I have 2006 GMC Sierra SLE 4WD 5.3 liter and my engine light comes on giving me the code PO449 Evaporative Emission Control System Vent Valve/ Solenoid Circuit Malfuction. What could cause this code to...

There is a solenoid that open and closes with 12 volts, usually located close to the fuel filler tube area. This open to allow you to fill your tank, then closes after some inputs for the computer are satisfied, and then a pressure sensor verifies the system is working. First, make sure the cgas cap is tight, and if the light doesn't go away in a couple days of normal driving, get the solenoid checked.

No heat

You probably just need to backflush your heater core. You can use a hose to flush it back and then forward. You'll be surprised at how much sludge and gunk will come out.
