this is the main code .. the other will be triggered by this ?? IMRC intake manifold runner control .. 15) DTC P1516, P1517, P1518 & P1519 DTCs P1516 and P1517 indicate control circuit failure. DTCs P1518 indicates IMRC stuck open. DTC P1519 indicates IMRC stuck closed. Possible causes are: Faulty vacuum hoses. Faulty vacuum solenoid. Faulty vacuum actuator. Cables improperly routed, binding or seized. Damaged or disconnected IMRC housing return springs. Lever return stop obstructed or bent. Lever wide open stop obstructed or bent. IMRC actuator cable or gears seized. On models with electric IMRC system, visually inspect IMRC cables for correct routing. Ensure cable core wire has slack at IMRC housing and stop screw contacts lever. On models with vacuum operated IMRC system, ensure sensor linkage is attached and secure. With engine running, lever must contact closed plate stop screw. On all models, operate IMRC plates while checking for binding and sticking. If any faults are found, repair as necessary. If no faults are found, go to next step. 16) Check IMRC Function If IMRC is vacuum controlled, start engine and allow to idle for 20 seconds. Turn ignition off. Turn ignition on. Using scan tool, access OUTPUT TEST MODE. Turn all outputs on. When IMRC is commanded on, lever(s) should rotate to full open position. One or both levers should contact wide open stop (one lever being slightly off is acceptable). IRMC levers should cycle fully from closed to open position. If faults are present, go to next step. If no faults are present proceed as follows: With DTC P1516 and/or P1517, go to step 64). With DTC P1518, go to step 26). With DTC P1519, go to step 29). #18 bottom middle of diagram on 3.0L 4V
