Re: cannister purge solenoid

the solenoid is for your EVAP system witch pulles a vacumn on your fuel system. if you have a vacumn leak it can through this code. also check to make sure that intake vacumn is being applied to the solenoid

Re: cannister purge solenoid

Are you getting any other codes like P0440 ???? check your gas cap a loose or bad cap will cause a large leak in the EVAP system..alot of people call this the "gas cap code"

What has happend is the PCM (computer) has seen a leak in the EVAP sytem and has turned on the light.
Here is how the PCM runs the test
The evaporative emission (EVAP) system is checked by applying vacuum to the EVAP system and by monitoring for a vacuum decay. The Powertrain Control Module (PCM) monitors the vacuum level through the fuel tank pressure sensor signal. At an appropriate time, the EVAP canister purge valve and the EVAP vent solenoid are turned ON, allowing the engine to draw a small vacuum on the entire evaporative emission system. After the desired vacuum level has been achieved, the EVAP canister purge valve will turn OFF, sealing the system. because the PCM is not detecting the expected vacuum. This can be caused by the following components with the conditions listed below:

The fuel cap for the following conditions:
Missing
Malfunctioning
Incorrect
The fuel tank pressure sensor for the following conditions:
Disconnected
Malfunctioning
The EVAP purge line for the following conditions:
Disconnected
Damaged
Pinched
Blocked
The EVAP vent hose for the following conditions:
Disconnected
Damaged
The fuel tank vapor line for the following conditions:
Disconnected
Damaged
Pinched
Blocked
The EVAP canister purge solenoid valve for the following conditions:
Disconnected
Malfunctioning
The EVAP vent solenoid for the following conditions:
Disconnected
Malfunctioning
An open ignition feed circuit to the following components:
EVAP vent valve
Purge solenoid
A damaged EVAP canister
A leaking fuel sender assembly O-ring
A leak in the following items:
Fuel tank
Fuel filler neck
