Installed blocking plate on 02 i35

[I-rock-35]

Hi I'm new here so if you can help me in any way it would be appreciated.

So I searched on the forum about the p1800 code and seen the nwp blocking plate was a cheap and safe way to fix the service engine soon light. After I installed it I had my friend clear the p1800 code and the next day the light came back on and still shooting the same code. How can I fix that problem because I hate seeing that service light on after thinking the plate would fix that problem

The p1800 code won't be fixed by replacing the Vias plate. That code is for the solenoid itself, so if you took it out you'll have to put it back in, otherwise you might need a new one to get rid of the code.

Oh okay thanks for help now were can I buy a solenoid because alot of the auto stores such as advanced auto and auto zone here in Chicago don't carry them for my i35 and I don't wanna spend a whole lot on it either

Dealer or used. I'd check the diff in price, (if any), between Infiniti and Nissan dealers.
