What does the P2073 code mean?

The P2073 code is a diagnostic trouble code (DTC) that indicates a fault in the throttle actuator control system. This system controls the throttle plate in the engine, which regulates the amount of air that enters the engine. Understanding this code is important because it can affect the performance of the engine and cause other issues if left unaddressed.

In other words, if you don’t fix the code immediately, it’s only a matter of time before your throttle response goes completely off and triggers shuddering and acceleration issues.

What causes the P2073 code?

Each of the potential causes can manifest in different symptoms which makes it difficult to pinpoint the exact source of the code. To make it worse, some symptoms are pretty similar to bad spark plugs or ignition coil issues, so here’s a list of the most common culprits behind this code:

Bad throttle actuator control motor

A faulty throttle actuator control motor can lead to the P2073 code by causing issues with the intake manifold tuning (IMT) valve. The IMT valve is responsible for controlling the length of the intake manifold runners in order to optimize engine performance and efficiency.

If the throttle actuator control motor fails, it can cause the IMT valve to malfunction as well, leading to inaccurate sensor readings and triggering the code.

Faulty throttle position sensor

A bad throttle position sensor (TPS) can lead to the P2073 diagnostic trouble code. The TPS is responsible for monitoring the position of the throttle plate, which regulates the amount of air entering the engine. If the TPS malfunctions, it can cause a range of issues with engine performance and efficiency.

Damaged throttle body

A damaged throttle body can lead to the P2073 diagnostic trouble code. The throttle body is responsible for regulating the amount of air that enters the engine through the intake system. If the throttle body is damaged, it can cause a range of issues with engine performance and efficiency.

One way that a damaged throttle body can lead to the code is by causing issues with the intake manifold tuning (IMT) valve.

Which car models does the P2073 code affect the most?

While any vehicle with an intake manifold tuning (IMT) valve can experience the P2073 diagnostic trouble code, there are some specific car models that may be more prone to this issue than others. Here are a few examples:

• BMW M3: These high-performance vehicles from BMW feature advanced engine technology and emissions control systems, which can make them more likely to experience issues with the IMT valve and trigger the code P2073.
• Audi RS5: Like the BMW M3 and M4, the Audi RS5 is a high-performance vehicle that utilizes advanced engine and emissions control technology. This can make it more prone to issues with the IMT valve and related components.
• Porsche 911: The Porsche 911 is another high-performance vehicle that may be more likely to experience issues with the IMT valve and trigger the P2073 code. This is due in part to its advanced engine technology and emissions control systems.

How to diagnose the P2073 code

Diagnosing the P2073 code requires specialized diagnostic tools and knowledge of the throttle actuator control system. The first step is to use a scan tool to retrieve the DTC and any other related codes. From there, you can use the following diagnostic methods:

Perform a visual inspection

The first step in diagnosing the P2073 code is typically a visual inspection of the intake manifold tuning (IMT) valve and related components. This can include checking for signs of damage or corrosion, loose connections, and other visible issues.

Electrical testing

The next step is often to perform electrical testing on the IMT valve position sensor circuit. This can involve using a multimeter to test for continuity and resistance in the wiring, as well as checking the voltage readings from the sensor itself.

Throttle body inspection

If the IMT valve and related components appear to be in good condition, your mechanic may inspect the throttle body for signs of damage or malfunction. A damaged throttle body can also lead to the P2073 code.

How to fix the P2073 code

Once the cause of the P2073 code has been identified, you can apply one of the possible solutions to fix the issue. The specific steps will depend on the cause of the code, but some potential fixes include:

Replace the IMT valve position sensor

The IMT valve position sensor is responsible for providing accurate readings to the engine control module (ECM) about the position of the IMT valve. If this sensor is faulty, it can lead to inaccurate sensor readings and trigger the P2073 code. Repairing or replacing the sensor can often resolve the issue.

Replacing the throttle actuator control motor

If this motor malfunctions, it can cause issues with engine performance and efficiency, as well as trigger the P2073 code, so replacing the motor can often fix the issue.

Repair electrical or connection components

In some cases, other components related to the IMT valve and throttle body may be causing the P2073 code. These can include wiring and electrical connections, as well as other sensors and control modules. Repairing or replacing these components can help resolve the issue.

How to prevent the P2073 code

Preventing the P2073 code from appearing in the future requires routine maintenance and care of the throttle actuator control system. This can include:

• Regularly cleaning the throttle body
• Replacing the air filter as needed
• Checking and repairing damaged wiring or connectors
• Replacing the throttle position sensor as needed
• Regularly inspecting the throttle actuator control system for signs of wear or damage

By taking these preventative measures, you can reduce the likelihood of the P2073 code appearing and ensure that your car runs smoothly and efficiently.

Our take

Overall, dealing with code P2073 can be pretty difficult if you don’t know how to approach the issue. Before you know it, the code could lead to some severe issues and that’s something you’d want to avoid to keep the throttle response precise.

So, our team of experts hopes that this guide will serve you well on the path toward dealing with the code and preventing it from appearing again in the future.
