Can anybody lead me in the right direction. I have a few diagnostic codes that I'm not sure about: 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 Smile

Re: Diagnostic Codes Not Sure How To Fix Sign In
The first 3 codes are to do with the EGR sensor. Click here to find diagnostics for the EGR system. Ther 513 is for low voltage. Check the battery voltage to be sure it has more than 10.5 volts all the time. If voltage falls below 10.5 replace battery. If voltage stays over 10.5 volts, replace the PCM. Click here to find how to erase the codes.
