    The codes are usually correct but in many cases only tell you where to start diagnosing the problem. A professional grade scan tool lets you look at sensor values to see if they are in range or out of range before replacing the sensor. Professional grade sensor also allows you to look at freeze frame data when the fault occurs and Mode 6 information which gives a better chance of fixing the problem right the first time.

    thanks...putting the car in neutral at the stoplight stops the stalling while stopped...
