P2072 Fault Code

Throttle Actuator Control System Ice Blockage

• What does that mean?
• Symptoms
• Causes
• Solutions

The Throttle Actuator Control System Ice Blockage fault code indicates that there is an issue with the throttle actuator due to ice formation. This condition can prevent the throttle from opening or closing properly, affecting the vehicle's performance.

• Ice can form in the throttle body or on the throttle plate, particularly in cold weather conditions.
• This blockage disrupts the normal airflow, leading to poor engine performance or stalling.

What are the symptoms of the P2072 code?

Common symptoms associated with the Throttle Actuator Control System Ice Blockage include:

• Engine stalling or hesitation during acceleration.
• Ill responsiveness from the throttle when attempting to accelerate.
• Check Engine Light illuminated on the dashboard.

What causes the P2072 code?

There are several potential causes for this fault code, including:

• Ambient temperatures dropping below freezing, causing moisture to freeze inside the throttle system.
• Inadequate heating around the throttle body due to a malfunctioning heating element.
• Contaminated air intake systems that introduce moisture.

How to fix P2072?

To address the Throttle Actuator Control System Ice Blockage, consider the following solutions:

• Inspect the throttle body for ice accumulation and thaw if necessary, using methods that do not damage components.
• Ensure that the air intake system is clean and free from contaminants that may introduce moisture.
• Check the heating system around the throttle body for proper operation and repair or replace it as needed.
