Vacuum Line
Hi, I'm new to toyotas and trucks in general. I was looking over the engine and found the egr valve was not hooked up to vacuum. The line that is suppose to go to the egr goes to a little round thing off the manifold with three vacuum inlets, with two blocked off. But I can't find that thing any where in the vacuum diagrams. I can't find any other areas where a vacuum line is missing. I am at a lost. Here is a picture to better explain

The EGR modulator (round thing on the valve cover) attaches to the lines off the throttle body and the BVSV that siits under the throttle body and is temperature controlled. The hard lines along side the valve cover carry those vacuum lines back and they pretty much connect such that you have no vacuum lines crossing over each other:

thank you for the link to the pictures that helped alot.
Quick question the sensor in the bottom right of the picture, is there a cap on the back line? also on the VSV is it capped on the back? http://www.4crawler.com/4x4/CheapTri...ine_Pix/8.html Mine has a line from the back line to the VSV and no cap on the back of the VSV. I think this might be why my truck has problems starting. Thanks for your help. |
