P1518 - Intake Manifold Runner Control Malfunction (Stuck Open) The IMRC system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is less than an expected calibrated range at closed throttle. IMRC monitor signal circuit shorted to PWR GND or SIG RTN
Damaged IMRC actuator
Damaged PCM
An IMRCM PID reading approximately near 1 volt at closed throttle may indicate a fault



can someone break this down for me.
