So I recently had my check engine light turn on. I went to my local pep boys and had them give me the codes it was showing. I have a 1998 lexus es300 and the codes I received were

P0500 - Vehicle speed sensor
P0441- Inccorect purge flow evap system

I was wondering if anyone can give me info on these two fixes? From what i've read the evap system fix is pretty easy? I read it takes about 20min to fix. What I'm trying to find out is more about the vehicle speed sensor. Thanks in advance!
