2003 Pontiac grand am “Trac Off” light on in some when car was stoped. Light will auto turn off (at the most of time) when drive 30~60 sec later. From owner manual, it said properly is engine problem.  
  
 But, if it is speed sensor problem, how to determine which side of sensor need to be checked? Thanks,
