The code P0015 is a bank 1 timing over retarded warning. The P0030 code stands for the heated oxygen sensor malfunction, which also pertains to bank 1. The oxygen sensor malfunction could be due to a failed sensor, heater, or any of the electrical components. This is the type of code that is leading you towards looking into the circuit for this sensor. Examine the wires, terminals, and fuses closely to make sure they are all working, clean, dry, and tight. If needed, replace the sensor, wire, or fuse. The retardation of bank 1 causing the first code could be due to this oxygen sensor issue. After resolving the oxygen sensor, the next step is to have the oil, transmission fluid, and possibly the coolant changed in the vehicle. After this maintenance has been completed, test drive the vehicle, and see if the codes reset.
