My CEL light came on.
Checked for codes and found 0807 -- EVAP Canister Purge Control Valve Circuit Fault.
Anyone dealt with this before?
Anyone have any ideas?

PS -- thanks to everyone here who has helped me out so far.
I've only had my Maxima a few weeks. Changing the coolant temp. sensor fixed my hard-start and stalling problems (best 30 bucks I ever spent).
Special thanks to renatonetmail for running carfax report for me.

 

the evap purge control valve is pretty common failure and can be replaced at jerryromenissan.com for 60 dollars plus shipping

 

Here's some info I found...
The code is listed as an OEM (Manufacturer) type code and it translates to a P0443,the 0807 is Nissan reference # and the industry standard SAE #P0443 is the Evaporative Purge Control solenoid circuit. There have been several Technical Service Bulletins from Nissan regarding premature failures of this system due to environmental situations, i.e.: water and corrosion. This trouble code usually indicates the canister purge solenoid is defective, but there are several updates for this system and if your car does not already have the water separator then it will need to be installed as well. Water intrusion into the hoses and solenoid are what commonly cause the failure; the fix would be to install the separator kit and probably the solenoid. The system will need to be inspected to determine which components are needed since there is up to 10 different pieces that make-up the package and not all are necessarily needed. The problem will not cause any performance or running problems but definitely affects your emissions and should be repaired soon. Though the kit comes from Nissan it can be ordered and installed at any competent independent garage and the labour should be no more than 1 hour for installation, plus the evaluation time. In regards to your second question, do you know whether the Evap system has been updatedwith the water separator repair package? If not that will cause very premature failure of the solenoid, and yes the canister purge valve is what were both referring to. The other possibilities are if the canister itself has been damaged and is allowing charcoal pieces to obstruct the solenoid, this should have been checked before the solenoid was replaced. Check your records as to what parts were replaced in Dec; see if there is any mention of a tube kit, bracket assembly or canister etc.

 

Thanks TickingVTC.
Is it pretty easy to replace?
I can't even go out and look at my car right now because of the weather.

 

yup you will laugh how simple...i think this will clear your code because you have a specific emissions code. You will fail emissions until this guy is replaced ...dont forget to reset the ecu...any other questions PM me
