Default Error Code P0446 2001 Tahoe

2001 Chevy 4X4 5.3L Tahoe with 200K miles

check engine light is on,autozone says code is P0446. This is what their ticket says:

The PCM has determined that a malfunction exists in the electrical circuit for the vent valve/solenoid in the evaporative emission control system.

Definition:
EVAP (Evaporative Emission System) purge/vent solenoid circuit condition

Explanation:
The solenoids and system wiring are monitored for opens or shorts

Probable Causes
1- Purge or vent solenoids defective
2- Check connevtor and wiring
3- Fuel saturated vapor canister
4- Failed EVAP vent solenoid

If the Vent solenoid is defective, what effects would this cause to the motor? Could it cause the motor to miss at low RPM?


Any info and help is appreciated.

Thank you in advance for your help!

Welcome to the forum

To the best of my knowledge the evap system witch is an emissions system should not affect drive ability, at least not in the sense of a miss or rough idle, the EGR which is also emissions could cause a rough idle.
With that many miles I would suspect fuel delivery / ignition

Welcome to the Tahoe forum. Remember that DTCs just point to an area of a problem and usually require further troubleshooting to determine the underlying cause.
