What is OBD-II Code P201E – Intake Manifold Runner Control Actuator Internal Performance Bank 2
As a mechanic, I frequently come across OBD-II codes in my work. These codes help diagnose issues with a vehicle’s engine and provide a starting point for repairs. One code that I have encountered multiple times is P201E, also known as Intake Manifold Runner Control Actuator Internal Performance Bank 2. In this article, I will explain what this code means, discuss the possible causes of the issue, and provide steps for repairing it.
What is OBD-II Code P201E?
The OBD-II code P201E indicates that there is an issue with the Intake Manifold Runner Control Actuator (IMRCA) in Bank 2 of the engine. The IMRCA is responsible for controlling the airflow in the engine, which helps regulate engine performance. When there is an issue with the IMRCA, the engine may experience poor performance or possibly even fail to start.
Possible Causes of P201E
The most common cause of P201E is a malfunction in the IMRCA. This part may become clogged or stuck, preventing it from moving smoothly. Additionally, electrical issues can cause the IMRCA to fail. The wiring connecting the IMRCA to the vehicle’s computer may become damaged, causing the computer to receive incorrect signals from the IMRCA.
Another potential cause of P201E is a vacuum leak. The intake manifold draws in air from outside the engine to mix with fuel and create combustion. If there is a leak in the vacuum system, this can disrupt the air/fuel mixture, leading to poor engine performance.
Symptoms of P201E
There are several common symptoms of an issue with the IMRCA in Bank 2 that can trigger the P201E code. The first sign of trouble may be the check engine light turning on, which can indicate a range of issues with the engine. Additionally, the vehicle may have difficulty starting, or the engine may stall while driving. Drivers may also experience reduced power or acceleration, and the engine may produce a rough, erratic sound.
How to Fix P201E
Fixing the P201E code requires identifying and addressing the underlying issue. If the IMRCA is stuck or clogged, it may need to be cleaned or replaced. Similarly, if the electrical connections to the IMRCA are damaged, they may need to be repaired or replaced. A vacuum leak can be repaired by locating and sealing the leak using specialized equipment.
In order to pinpoint the cause of the P201E code, it is best to bring your vehicle to a trusted mechanic or dealership. They can use specialized tools to run diagnostics on the engine and identify the specific issue. Once the problem has been identified, they can recommend the best course of action to repair it.
