I apologize. I’m trying really hard to understand the system. I keep re-reading your messages. I think I was thinking of it backwards. (I thought it was closing the VSV with 12v to build pressure on the other side. Then opening and pulling the EGR with the built up pressure all at once) but I...

Okay… so I test the plug from the harness. And I’m not getting 12v. (I assume it should give 12v when it’s cold so the VSV can build pressure) I started looking at the harness and noticed a large cord sitting on my starter not hooked-up. What is that for? I plan on looking up a wiring...

So I tested the VSV with the truck off. And I can hear a small click when I give it 12v from the battery. So it must be okay. I was really thorough when I connected all the vacuum lines the first time. But I’m going to take it apart and double check. Only other thing I can think of is the ECU...

Okay. First test passed. Second test failed. But its a brand new OEM EGR VSV. I’m going to return it I guess. And go with the Dorman “replacement” I have seen in the forums. I watch most of those videos. That’s why I got as far as I did. I really appreciate your help. I hope this is the actual...

Okay fair enough. I’ll leave the temp sensor alone for now. And based on what you said… it seems like no pressure is building (through the red line) And Just to be clear with the first test… I plug the line between the EGR and the EGR VSV or between the EGR VSV and the “T” connector?

Thank you!!! I am going to test tonight and report back in a day or two. The current code is the PO401. Is it a possibility that the temp sensor is stuck in the “on” position. Therefore leaving the VSV closed?

Does it still pass smog once deleted?

Thank you for the response! I have cleaned that hard line as well. It’s all clear. I haven’t changed the temp sensor. I guess I’ll give that a shot. Does the temp sensor act as a valve?

I have read most of the forums on here. But none of them touch on what I’m dealing with. I own a 1995 Land Cruiser (with OBDII) If you look at the attached image, you’ll see my color coding trying to solve the issue. Green means I have tested it, and/or replaced it. Red means I’m getting no...
