2001 Silverado 1500. The turn signal works just fine, but the parking light doesn't turn on. I assume this is either a fuse or a relay. Can anyone point me to which fuse or relay this would be?

Thanks for all the help. I ended up replacing the vent solenoid valve and all codes went away after a week of driving

1. Yes that's correct. 2. ok thanks 3. Interesting. So this implies it's the sensor in the transmission?

1. Oh, right, 2001 Chevy Silverado 2. From what I've been told otherwise it could also be the gas tank pressure sensor, but I'm curious why that and the other codes would pop simultaneously. That seems strange to me. 3. This is why I'm suspecting it's maybe a wiring issue. If the harness near the rear left wheel has some kind of issue perhaps it would trigger both of these?

All three of these popped at once which seems odd to me. P0446: Evap Emission System Vent Control Circuit C0292: Lost Communication With Engine Control System C0298: Powertrain Control Malfunction I'm just getting the static Service Engine light, no other lights or screen messages while starting or driving. Is this a wiring issue of some kind?
