Codes or no Evap Codes, the issue is in that system
You need a schematic of the evap system, so you can
test the solenoid or valves,mainly the vent solenoid, if that
applies Not the purge valve, that is up front & opens to allow
engine vacuum to draw out fuel fumes from the tank.

Codes po 123 po335 po446

Code 123 is a problem with the throttle position sensor circuit.
Code 335 is a problem with the crank position sensor circuit.
And code 446 is for a EVAP control valve problem.
These components would need to be tested to find out if they are faulty.

If the p0440 codes come up is the car still ok to drive 96 chevy blazer

Hi, P0440 indicates your computer is not getting a drop in fuel tank pressure when opening the evaporation system purge valve. This is not a safety issue, as the gas cap will release any excessive pressure, so you can still drive the car. The problem may be a leak in the evap system or a failed purge valve. Please let me know if you would like some troubleshooting steps or if you have other questions, and thanks for using FixYa.

'99 olds 88 diagnosed PO 446 evap vent control problem

Your code means:

P0446 onepx.gif EVAP Canister Purge Vent Blocked

Some of the possible causes:

EVAP vent fresh air hose is clogged, kinked or restricted
EVAP Vent solenoid is contaminated, damaged or has failed
FTP sensor is out-of-calibration, damaged or "skewed"
PCM has failed

All tough thing for a lay person to check. You don't have to take it to the dealer, any repair garage that has the proper equipment can fix this for you.
