I also have a 2006 GMC that has the exact problem. The machanic that had check it, Said that I would have to get the part from the dealer. And that the gas tank would have to be dropped to get to the location where it is at. The machanic also said that he has worked on serval of them that needed to be replaced.
On a 2009 GMC Sierra, the purge valve solenoid is typically located near the engine, mounted on or near the intake manifold. It is connected to the evaporative emissions system and the fuel tank. To access it, you may need to remove other components or covers, depending on the specific engine configuration. Always consult the vehicle's service manual for precise location details and removal instructions.
The EVAP vent solenoid on a 2006 GMC Sierra is on the driver's side of the vehicle. It is on a bracket next to the gas tank.
It depends on which solenoid you mean. The STARTERsolenoid is integral to the starter.
Starter solenoid? One top of starter--follow + battery cable
There is one solenoid on the charcoal evap. canister in the engine compartment. There is another one located near the gas tank underneath the chassis. That is the one that usually goes bad as road salt and moisture attack that one.
there should be a eng. info and emission sticker in the eng compartment it will say California emission on it
reverse gear does not work off a solenoid do you have 2nd and 4th gear or just rev missing
I have a 1978 Sierra 1500 and mine is near the secondary tank, passenger side of the truck.
To repair diagnostic codes P0172 (System Too Rich Bank 1), P0175 (System Too Rich Bank 2), and P0449 (Evaporative Emission Control System Vent Valve/Solenoid Issue) on a 2007 GMC Sierra, start by checking for vacuum leaks, as they can affect air-fuel mixture and trigger rich codes. Inspect the mass air flow (MAF) sensor and replace it if necessary, along with checking fuel injectors for proper function. For code P0449, examine the EVAP system components, including the vent valve and associated wiring, for faults or blockages. Clear the codes and test drive the vehicle to see if the issues persist.
Trouble code P0441 means:Evaporative emission control system,incorrect purge flow
This can be caused by a bad sensor, solenoid, or loose connection on the transfer case.
Possible o2 sensor
