Yes, the codes can still be retrieved and read by an OBDII scanner, even if the bulb is missing from the Check Engine Light. Don't understand why you would want to pull the bulb out unless you are trying to "fake" out of passing an emmissions or similar test on your vehicle. The Check Engine Light plays a very important part in warning of potential problems - I wouldn't pull the bulb out.

Pull the codes from the computer, match the code to the troubleshooting procedure, follow the procedure to find the source. Repair the source, light will go out if that was the only problem. There are "monitors" or self test the computer runs the car through, if a problem occurs, it may not run all of the self tests until that problem is taken care. Therefore, another problem may exist. It is emission related. We just found out that the check engine light on our 1993 Toyota Pickup is due to a bad "knock sensor".
