I keep getting this code, even though I have now replaced ALL the components in the EGR system: EGR valve, EGR modulator, EGR Vacuum Switching valve (VSV), and all 5 of the EGR vacuum hoses. I used genuine Toyota parts. All ports and pipe are clear. Both EGR gaskets were replaced. I am getting 12 volts at one of the two terminals that connects to the VSV. Don't know what else I can do. I'm having no other codes or problems with the car. Could it be the ECU is bad anyway, even though there are no other issues?
have the same problem?
