This past weekend my car was driven about 15 miles with the emergency brake on. After that the check engine light starting blinking. I went by Autozone and the codes they gave me were P0500 Vehicle Speed Sensor and P1101 Neutral Switch Circuit High Input (A/T). NEither one sounds super urgent, the car is driving fine with no issues. I am just wondering if anyone has any ideas on fixing the problems or if it is super urgent.
