P0500 means the ECM is not receiving a valid vehicle-speed signal. C1541 is an electric power-steering code related to missing/abnormal vehicle-speed information. That explains why the check-engine light and power-steering warning light can appear at the same time.
Start by connecting a scan tool capable of reading live data and look at Vehicle Speed while driving slowly. Also check the individual ABS wheel-speed sensor readings if the scanner supports ABS data. Let me know what you find. This might be two separate issues.
