obd codes. on 2001 Kia Optima

Our 2001 Kia Optima showed 2 obd codes today. P1529 & P0715. When I was driving I heard a loud jolt and jerk and the car lost power. Then the check engine light came on. Does anyone know what may need fixed. We know what the codes mean, just not what to do to fix it! Please help.

This is a quote from a Kia specific forum "p1529 - The TCM can request activation of the MIL lamp Via a communication line to the ECM. This is only a request from TCM to ECM to turn the MIL on. The fault code is stored in the TCM. Select A/T part on the Scantool and monitor DTC related automatic transaxle system"
P0715 - A/T Input speed sensor circuit malfunction
You will find test procedures for the more serious code P0715 code at Kia's own website for free. Kia as a car manufacturer put a lot of great technical information and work shop manuals on line for free for Kia owners. www.kiatechinfo.com
