CEL throwing some codes..

[kjweston]

Its throwing:

P1491
P0500
P0455

I know the P0500 is the speed sensor which I got replaced but haven't disconnected my battery to reset it..

And based on a couple slightly different lists of codes I've found on here the P0455 is like EVAP leak or something. How do I fix this? And what is it?

And finally I couldn't find what P1491 is. If anyone knows and would know what I need to do to fix these please LMK.

Thanks, Chase

P1491 Cooling Fan Relay Control Circuit

Can't really help you on anything other than that, sorry dude.
But check out the south section. We're having a m&g in Ocala in april.

So what do I need to replace a relay or something?

and alright man ill check it out.

Your cooling fan relay is about 10" below the battery,the one on the inner fender and not the SRS sensor that is on the radiator support(they are very close to each other).It's common for them to overheat and burnout.The updated relay has a massive heatsink on it,about $50 from the dealership and takes about 5mins to change.

alright thanks ill look into that.

anyone else on the EVAP P0455 code?

Check the hoses that route up around the battery and down the firewall down. Check for cracks and a good seal. It only takes a hole .010 of an inch I think the standard is for a large leak code to blow. Odds are it’s a bad hose. Also check the gas cap you never know. If not it has to be hooked up to a smoke machine to fine where the leak is coming from.

That is the source of your P0455, most likely.

Alright so.. New section of hose fix P0455.. New cooling fan relay on the fender fix P1491.. And P0500 has been fixed just not reset. Alright I got it thanks guys.

Turned out to be just the fuse. But it wasn't 20 cents ha.. more like $4.79 or something for just one 40a fuse. but while I was there I got more coolant and new hood supports.. no more carrying around a stick!! and best of all no more CEL! finally!
