P1520 Fault Code: Understanding The Description And Troubleshooting Tips
The P1520 fault code refers to a problem with the Intake Manifold Runner Control (IMRC) circuit. The IMRC system is responsible for controlling the airflow into the engine cylinders.
It consists of motorized actuators and butterfly valve plates that open and close to regulate the intake air passages. 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 P1520 code is triggered when the signal from the IMRC system is outside the expected range. This could indicate a fault in the circuit, such as a wiring issue or a malfunctioning actuator.
It is important to address this issue promptly to ensure proper engine performance and fuel efficiency.
FAQ
When the engine light is on in a vehicle and the fault code P1520 is displayed, it indicates a problem with the Intake Manifold Runner Control (IMRC) actuator. This could be due to a faulty actuator, an open or shorted actuator harness, a poor electrical connection in the actuator circuit, or a faulty Powertrain Control Module (PCM). To fix this issue, it is recommended to visually inspect the wiring harness and connectors, check for any damaged components, and look for any broken, bent, pushed out, or corroded connector pins.
If you’re seeing the P1520 fault code and your engine light is on, it could be due to a few different causes. One possibility is a faulty Intake Manifold Runner Control (IMRC) actuator. Another potential cause is an open or shorted IMRC actuator harness, or a poor electrical connection in the IMRC actuator circuit. Lastly, a faulty Powertrain Control Module (PCM) could be to blame. 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.
If you’re experiencing the P1520 fault code in your vehicle, with the engine light or service engine soon warning light on, there are a few steps you can take to fix it.
