i have replaced the egr valve, the egr solenoid and sensor, I have cleaned out the port to throttle body blown out all vacuum tubes, and the hoses going to the egr sensor, and the tube toing from the exhaust pipe to the egr valve, i keep getting a code for insufficient flow for egr, where does the system get a signal from to cause the egr solenoid to operate the egr valve, i do not have an electrical schematic to use in troubleshooting.
