2004 Impala Fuse
 

Hi everyone. I was wondering what exactly the fuse "ENG DEVICES" goes to. I'm sure it has a cause but i don't know very much about cars electrical systems. I'm sure someone on here would know better than me. Thanks in advance for any and all help.

The reason you're asking has me to ask why are you asking? Engine devices

I'm just curious what it powers exactly because when it was removed my Impala ran fine it just caused the check engine light to come on. I replaced it and the check engine light went off I just wanted to see if it could have caused any damage to my car and specifically my engine. Thanks.

From page 5-101 of owners manual:

ENG DEVICES: Canister Purge Solenoid, Mass Air Flow Sensor (MAF), AIR Pump Relay & Valve Control
