Hello, I have been searching around for some help with a check engine code my car gave me. The code is P0501 and the code reader said it was an error with speed sensor A. The ABS light and check engine light are both on. The speedo and rev indicators both work. The only difference I've noticed is that the steering is a little loose. Can anyone tell me where this "Speed sensor A" is located on my car? It is a 2007 hyundai elantra, manual transmition (if that changes anything). Does anyone have a troubleshooting tips for this?
