RE: DTC code p1665

The code is for the evap vent solenoid, its probably the vent solenoid itself. You can take the solenoid off and hook some wire to it from a battery and it should click each time you touch the battery if it doesn't then its bad.

RE: DTC code p1665

it's an evap code for your vent valve you can check fuse 42 in your fuse block and 12v on the pink wire at the vent valve but9 chances out 10it's the valve if u dont know where it is it's
Behind the left rear fascia splash shield in the wheel well. good luck!

Help

so i have a 98 monte carlo. its been parked for a while because of the service engine light. i finally got someone to look at it today and actually scan it and it gave me two codes.
first one was P0440 Evaporative emision. and i changes the fuel cap because thats what everybody told me to do. idk if it has worked or not because i just did it.
any help with that one?

the other code was P1665 which the scanner told me it was fuel level output system or EVAP vent control system?
i really dont know what this means. and i need help ASAP. this is my only car and i need it to drive to school and work. does someone have any ideas? please help.

Welcome to the forum. P1665 in your vehicle does NOT have anything to do with "fuel level output system." Check your EVAP vent solenoid circuit according to above posts.
