Q: IMRC valve stuck - where is it? on 1999 Ford Escort

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Diagnostic code P1518 sez the intake manifold control runner is stuck open. I can't find any mention of this in the Chilton Repair Manual, and could not find the part at Kragen Auto online. Where is it? How do I check it? and how do I fix it? Thanks!

You will find it located on the lower intake. The IMRC actuator is located on the lower intake drivers side. The 2.0 liter engine has an upper & lower intake.
I was able to find some info in my Chilton Manual, sorry it's not much info but hopefully it helps.
Trouble Code: P1518 (2.0L L4 Auto)
Intake Manifold Runner Control Malfunction (Stuck Open)
Trouble Code Conditions:
Engine started, and the PCM detected the IMRC Monitor signal was less than its expected calibrated range at closed throttle. An IMRCM PID of 1v at closed throttle indicates a fault.
Possible Causes:
* IMRC monitor signal circuit shorted to power ground
* IMRC Monitor signal circuit shorted to signal ground (return)
* IMRC actuator is damaged or has failed
* PCM has failed
