The bottom hose on my imrc valve looked like it was cut or something and was throwing a P2004 code so I went to replace it, and I cannot find the other point where the hose connects.

Hello,

The top hose: usually goes to the intake manifold vacuum source. Bottom hose: goes to the IMRC actuator diaphragm or control valve.

P2004 - Intake Manifold Runner Control (IMRC) Stuck Open (Bank 1)
