Go to the top of the main Seville threads page and read the entire sticky thread "How to pull codes". When you are familiar with your car's system, return to the thread and open the link with "obd1" in the URL and click on the Main Index links for the definitions of P,B,C, and U codes.
P 070 is a code comprised of the module identifier: P = PCM; 070 is the code numerical sequence and the link will give you that description.
