I have seen here a replaced regulator overcame p0301 and other dtc codes on Toyota. Where would I find regulator on my car listed above, if there is one? Will be replacing EGR and plugs today so may want to replace that regulator as well. Thanks, rg

Hi,

Are you referring to the fuel pressure regulator? If so, they can cause misfires if they are not allowing the proper fuel pressure but it normally effects more than one cylinder. I attached the process of how to replace this. Plus a guide on how to test fuel pressure.

Let me know if you have more questions. Thanks
