Pepboys in Vallejo will check you codes but they charge a small fee. They wanted me to wait in line for 45 mins behind all the other people who were there getting their brakes done and radiators done. I'm not saying I should be allowed to cut in line but come on, it'll only take 2 mins to read a code. So I left and bought a code reader at Autozone (who won't check codes). So anyone in Vallejo, I'll read your code for free.
