P1518: Understanding The Causes And Solutions For This Automobile Fault Code
The P1518 fault code refers to a problem with the Intake Manifold Runner Control (IMRC) system.
This system consists of motorized actuators and linkages that control the opening and closing of butterfly valve plates in the intake manifold.
The IMRC housing has two air passages for each cylinder, with one always open and the other controlled by the butterfly valve plate.
The motorized actuator has switches that provide feedback to the PCM about the position of the linkage and plate. When the engine is running below 3000 rpm, the vacuum solenoid is energized, keeping the butterfly valve plates closed. Above 3000 rpm, the solenoid is de-energized, allowing the plates to open.
The P1518 code is triggered when the IMRC is commanded to close, but the monitor detects that it is actually open. This indicates a problem with the IMRC system being stuck in the open position.
FAQ
If you’re seeing the engine light or service engine soon warning light on your dashboard, the fault code P1518 could be the culprit. This code is often caused by a faulty Intake Manifold Runner Control (IMRC) actuator, an open or shorted IMRC actuator harness, a poor electrical connection in the IMRC actuator circuit, or a faulty Powertrain Control Module (PCM). To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.
