I have a 2002 kia spectrs gsx I just replaced the tps sensor and the rear oxygen sensor and I erased the codes at auto zone and the codes still come back and I thought the sensors were faulty and changed them and the same thing happen the codes come back on. What is wrong that it still reads the coded?

Both codes returning straight away means bad wiring or a bad PCM (computer)
