    is there a sensor that may have failed that will account for that? the oxygen sensor? could that be the problem?

I have a 2004 gmc Sierra 1500 ext can long box and the engine light is always on. I have taken it in to a few places and even had my brother check it out. I also have a code reader. I have never had a problem with it. When we hook up the code reader it says gas cap so we fix that and the light turns off till the next time I drive it. Have it checked out but it's probably nothing as I have come to realize its probably a dirty sensor somewhere.

Oil gage goes to 80 and stays there


Sounds like either a defective sender unit or guage in the cluster. Another slim possibility is the wire is shorting to the engine causing a false signal from the wire.

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.

I am getting codes Po449 and P0455 on my 2004 GMC Sierra 1500. I put a new fuel cap and then had the computer reset. The engine light went away but came back later that day. What do you suggest I do nest?


This indicates a fuel vapor leak or lack of purge flow in the EVAP control system. It means a large leak has been detected. 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.

Assuming you put on the proper gas cap and one of high quality, I would inspect the EVAP system for cuts/holes in tubes/hoses (you may hear a vacuum noise or smell fuel), repair if necessary.
