PCM Internal Voltage Failure Sign In

Can anybody lead me in the right direction. I have a diagnostic code that is PCM Internal Voltage Failure and EGR Temp. SEnsor Circuit above max. voltage, pressure feedback EGR circuit voltage low, insufficient EGR flow, pressure feedback EGR sensor voltage higher or lower than expected during KOEO. These are all my problems. I have no idea what they mean. Does anyone know of my cheapest way to solve the problem and about how much it would set me back. Thank you

As a wild guess, is this a Ford? Please give us make, model, year and engine size. The more information we have, the better we can help you. As Indy tech stated, please post the EXACT CODE NUMBERS.
