P0503 code help
 

so I was at a light yesterdya nad was playing with my interceptors and decided to check the codes just to see what I got,

I have NO CEL but I have a p0171 code. guessing from my
KN CAI

and I have a po503 code. thats a vehical speed snsing code, no problems so far just wondsering why I would have it ? my gauges seem to be working fine,

any thoughts?

Thats either an abs problem or a sensor on thew trans.

so... lol

should I worry theres no check engine light, it was just acode in there was it just a temp code or what?

most codes don't throw a CEL until it reaches the error again for the 2nd time.

oh ok. didnt know that, but do codes just get randomly throw sometimes? like lil computer glitches or something?
