Thank you for your great video. Helped me diagnose. I just did the diagnostics and need the same part. Maybe you could find the part name and number for those that may need it. And if you did a video on testing the vaccum switch, you should link it here and pin it to comments. Thank you for your time. Edit: ok you said vaccum switch. There was a Mighty Vac extension you could have used instead of the little piece of extra hose in case anyone has the MV but was thinking about picking up the little hose.
I have literally changed all the hoses, egr valve itself, the vst valve sensor on the bottom of the engine and cleaned everything thoroughly with electronics cleaner and this dumb light still comes back, I have pretty much replaced the entire system and this damn light still comes back, I'm at my wits end, it makes 0 sense
@Makula-px8fr same. My car threw an ECT code the same time as two different P0401 codes came. Still trying to diagnose problem. Bottom radiator ECT switch (I think) must be a good quality replacement or OEM
Thanks so much
God bless you
For share you experience
Good video thanks for sharing 👍
What if the needle barely moves on the gauge for the EGR modulator. Does this mean it's no good?
What's it called the peace u took off ??
thank you!
Can a simple hose from the EGR trigger the code?. In my case the top hose is cracked and damaged.
Yes, replace the hose for a few dollars and go from there.
Where’s the vacuum switch wall
Good video!
Thanks!
Please can you put the name and module of the pump that you used in the Check?

@Makula-px8fr A bad Ect is a po115 code This is a po401 code. How can Ect affect this ?

Check if you have vacuum coming out of the 2 vacuum ports on the Throttle Body at above 2500 rpm.
@@leosnake how do you check to see if you have vacuum coming out of the second throttle body port?
I checked with a vaccum gauge....I ended up removing the Throttle Body on mine...Ir was really full of gunk!
@@davidmarquez6500 the throttle body port P is clogged. They don’t show this much but is a common issue
