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!

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

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.
