egr and vacuum troubles

i don't know much about my motor or its workings, but i was changing a gasket and found some busted vacuum hoses and i broke a sensor..

i broke this and need a new one. whats it called?


this hose is broken:

i assume i can take it to lordco and ask for a new one, but i dont know where the other end plugs in.

another broken hose (this where the egr one goes?)


rear pass side of plenum (the one with no hose was.. you guessed it.. cut)


i need to replace that which is broken? can anyone help with part numbers or advise?

That looks like your EGR sensor. I "think" they sell those without having to buy a new EGR. The hoses you broke are EGR hoses. You can buy that hard line vacuum hose at any parts store. It comes in like a 12" roll.

That is the EGR diagnostic or feedback switch. They run about $10 at most auto stores.

The back port on the plenum goes to the cruise control, there should be a long vacuum hose from the cruise leading back the driver side and looping around to that port.

The rear most port on the EGR solenoid vacuum connector goes to the EGR valve. The forward one goes to a "T" fitting up under the plenum just behind the throttle body, the other side of the "T" goes to the evap. cannister.
