Code p0442 on 2007 gmc sierra

I have 14 volts to the plug for the vent solenoid. When plugged in the solenoid doesn't work. But when battery voltage is applied directly to the solenoid, it works fine.

Voltage regulator is going bad. Have alternator tested or go ahead and have it replaced. Also this would be a good time to have the battery tested. Usually an alternator that is over charging will "cook" the battery causing it to not charge, not hold a charge, to losing the gel/electrolyte solution due to boil out.

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.

The regulator is in the alternator. Did you check voltage at the battery? Nothing in the diagram jumps out at me. Is the check engine light on? Maybe we could get a hint if there was a trouble code.bc11b1d.gif

I wouldn't replace the plugs, just yet. This sounds like the vent solenoid. They are usually around the fuel tank and sometimes located on the charcoal canister, Which I believe is where yours is. Test it with 12 volts it should click. if it doesn't then replace this. On newer cars like yours, when the vent or purge solenoids malfunction, they will pop an 02 code. If the solenoid clicks then check the wires right at the plug . they tend to break there. And the gasket your looking for is the intake manifold gasket. And looking for the solenoid, look under the emissions and EVAP systems.

Po453 code for 1998 gmc sierra


P0453 - Fuel Tank Pressure (FTP) Sensor Circuit High Voltage-this usually means the vent solenoid is defective and needs replacement, but I would clear the code with a scanner (or disconnect the negative battery cable for five minutes) and see if it comes back-often this is set by:

  • Open on FTP sensor signal wire
  • Short to voltage on FTP sensor signal wire
  • Bad FTP sensor
  • Abnormally high pressure in fuel tank due to blockage in EVAP purge hoses or overfilled tank
  • Loose/damaged FTP sensor connector
  • Loss of ground to the sensor

Got code PO449 on the obd11 scanner, could you


p0449 is an evaporative emission code that indicates a problem with the canister vent solenoid.. without being able to scan and check all of the system I would recomend replacing the vent solenoid. I believe their was a GM TSB on that part and it has been modified.
please respond with fix details

2002 GMC Sierra 1500 fuel system


first off do not use a test light. use a circuit tester. what you saw as 5volts is called a reference signal. the cars computer(much like your home computer)works only off 5 volts. if you use a test light(the old kind with a light bulb.)you will fry the computer. second, are you saying the problem is still occuring after these parts have been changed?
