I know this is an older thread but it is just what I have going on right now. Code p1491 and a blown #39 25a fuse ( a/c condenser fan motor relay ). will get fuse tomorrow and see if anything else acts up. however I have two questions my scanner says code p1491 is "mfg installed emission control system" also would this have anything to do with my heat/ blend door or something acting up...NO HEAT. if so that would be great 'cause I dont wanna tear into this dash! and this is on my 02 3rd gen

Check engine light is on. Fan was not working and fuse 39 was blown. Replaced the fuse, swapped the relay, and cleared the CEL. Now the fan works, but the CEL stays on with the same p1491 code. I've read about other issues with the wiring inside the fuse box corroding. Think this could be related? Open to suggestions.
