hullo my car recently is having a fuel problem. it idles fine but when i step on the gas it is like the deleviery of the gas is intermittent and the car bucks. some times it stalls when i am starting from 0mph and giving it gas. the engine codes it shows are p 0481, 0480, 0443, 0499.. the 2 fan ones are i think related to damage i sustained on wire harness over winter.. if anyone can tell me what the other 2 mean and what may be going out on my car i thank you.

P0443
SYMPTOM
P0443-EVAP PURGE SOLENOID CIRCUIT
WHEN MONITORED
The ignition on or engine running. Battery voltage greater than 10 volts.
SET CONDITION
The PCM will set a trouble code if the actual state of the solenoid does not match the intended state.
POSSIBLE CAUSES
- Good trip equal to zero
- Vehicle History and Service Bulletin Investigation
- EVAP purge solenoid
- EVAP purge SOL control circuit open
- EVAP purge SOL control circuit shorted to ground
- EVAP purge SOL signal circuit open
- EVAP purge SOL signal circuit shorted to ground
- PCM

P0499
SYMPTOM
P0499-NVLD CANISTER VENT VALVE SOLENOID CIRCUIT HIGH
WHEN MONITORED
Engine running.
SET CONDITION
The PCM detects a short in the NVLD Canister vent solenoid circuits. One trip Fault.
POSSIBLE CAUSES
- Good trip equal to zero
- Vehicle History and Service Bulletin Investigation
- NVLD solenoid
- NVLD SOL control circuit shorted to battery voltage
- NVLD SOL control circuit open
- Ground circuit open
- PCM

 

thank you indeed. can you point me in the direction to go on how to fix it.. i have no idea what a "canister vent valve is"

 

Soulfire, Ill move tis thread over to the Neon Section for better input, but first what year neon do you have?

Btw Welcome to DF

 

my neon is an 05. I would like to try to tackle the repair myself if it is doable. i gernerally work on semis.. but.. with money tight i have to try my self ...

 

OK it is moved! Hope these guys can give ya some good pointers Good luck!

 

lol thanx our fellow dodge friends.
this is way too much electrical for me.
have you tried changing your plugs???

 

Looks like they are emissions/driveability codes....obviously. I'd check those two solenoids first.

 

yes i will check them. and a friend said it is possibly the clutch as it will rev and then catch jerking foward... but does anyone know where the solinoids are?
