I have a dtc P0503. Anyone know what the code is or what it is for. thanks

P0503 Vehicle Speed Sensor intermittent.


check and replace vss if needed

My speedo is accurate and everything seems to be fine....

Are you sure? You may not even be noticing it yet.

Mine pulled that code but I didn't notice the speedo being wrong for a little while. It only did it when the car was cold. Someone noticed it in the passenger seat and told me but when I looked, it was working fine again. I told them they were crazy.

thanks for the info, i will keep an eye on it....
