P2119 – Throttle Actuator Control Throttle Body Range/Performance

What is the P2119 Code?

The P2119 is a generic OBD-II trouble code that indicates a problem with the throttle actuator control (TAC) system. Specifically, it means "Throttle Actuator Control Throttle Body Range/Performance". This code is triggered when the powertrain control module (PCM) detects that the throttle valve is not in the expected position based on the throttle actuator control motor's commands.

Urgency and Severity

When the P2119 code is set, it's important to diagnose and fix the issue promptly. Depending on the underlying cause, you may experience symptoms like:

• Reduced engine performance
• Engine going into "limp mode" with limited power
• Rough idling or stalling
• Inability to start the engine in severe cases

If you are experiencing significant drivability issues, it's best to avoid driving the vehicle and have it towed to a mechanic for diagnosis. Continuing to drive with a malfunctioning TAC system can potentially lead to unsafe conditions or further damage.

Applicability

The P2119 is a generic code that can apply to any vehicle with an electronic throttle control (ETC) system, also known as drive-by-wire. This includes most modern vehicles from various makes like Ford, GM, Toyota, Honda, BMW, etc. However, the specific components and diagnostic procedures may vary somewhat between different vehicle makes and models.

Parts Involved

The main components of the TAC system that can trigger a P2119 code include:

• Throttle body: Houses the throttle valve and throttle position sensor (TPS). Controls airflow into the engine.
• Throttle actuator control motor: Electronically adjusts the throttle valve position based on PCM commands. Integral to the throttle body.
• Accelerator pedal position sensor (APPS): Sends the gas pedal position to the PCM.
• Powertrain control module (PCM): Controls the TAC system and sets the code if a problem is detected.

Common Causes

Some of the typical reasons the P2119 code may be triggered include:

• Faulty throttle position sensor
• Damaged throttle actuator motor
• Dirty or sticking throttle body
• Corroded or damaged wiring/connectors in the TAC circuit
• Faulty PCM (rare)

Diagnosis Steps

1. Scan for codes and document freeze frame data.
2. Visually inspect the throttle body and wiring. Clean the throttle body if dirty.
3. Use a scan tool to observe live data from the TPS and APPS. Look for irregular or erratic readings.
4. Test the throttle actuator motor and TPS circuits for proper voltage and resistance per manufacturer specs.
5. If no wiring issues are found, perform a throttle relearn/adaptation procedure.
6. Test drive and rescan to see if the code returns.

Repair Solutions

Fixes for a P2119 code may involve:

• Cleaning the throttle body if it is sticking
• Replacing a faulty throttle position sensor
• Replacing a damaged throttle actuator motor
• Repairing damaged wiring or connectors
• Replacing the PCM if faulty (rare)

Always follow the manufacturer's recommended diagnostic and repair procedures for the specific vehicle.

Repair Cost

The cost to fix a P2119 code can vary significantly depending on the root cause and the vehicle make/model. Some rough estimates for common repairs:

• Throttle body cleaning: $50-150 USD (€45-135 EUR)
• Throttle position sensor replacement: $100-300 USD (€90-270 EUR)
• Throttle body/actuator replacement: $300-1000+ USD (€270-900+ EUR)
• Wiring repairs: $100-300 USD (€90-270 EUR)

Diagnostic labor and any additional parts would be extra. Always get a quote from a trusted mechanic before authorizing repairs.

Prevention

Some ways to help prevent TAC system issues include:

• Regularly inspecting and cleaning the throttle body every 50,000-100,000 km (30,000-60,000 miles).
• Addressing any related codes promptly. The P2119 may appear with other TAC codes like P2135, P2138, P2101, etc.
• Avoiding aftermarket "performance chips" that can alter throttle mapping.

By understanding the P2119 code and following proper diagnostic and repair steps, you can restore proper throttle control and get your vehicle running smoothly again. If you are unsure about tackling the diagnosis and repair yourself, it's always best to consult with a qualified mechanic to ensure the job is done right.

Can I fix the P2119 code myself?

If you’re mechanically inclined, you might be able to clean the throttle body yourself. However, diagnosing and fixing other issues often requires specialized tools and expertise, so it’s best to consult a qualified mechanic.

What kind of scanner do I need to diagnose the P2119 code?

For European car owners, having a reliable dealer-level scanner is paramount. These scanners provide in-depth access to your car’s systems, allowing for accurate diagnosis and efficient repairs.

How can I prevent TAC system issues that cause a P2119 code?

Prevention includes regularly inspecting and cleaning the throttle body every 50,000-100,000 km (30,000-60,000 miles), addressing any related codes promptly, and avoiding aftermarket “performance chips” that can alter throttle mapping.

What other codes may appear along with the P2119?

Ignoring the code can lead to reduced engine performance, increased emissions, and poor fuel economy. In severe cases, it may cause catalytic converter damage or the inability to start the engine.

How long does it take to diagnose and repair a P2119 code issue?

Diagnosis can take 1-2 hours depending on the specific issue. Repair time can range from 1 hour for a throttle body cleaning to 4+ hours for a throttle body, wiring harness, or PCM replacement.

Will the P2119 code clear itself after repairs are made?

The code should clear after repairs if all the issues have been properly resolved. However, it’s best to clear the code with a scan tool and then test drive to verify the fix. If the code returns, further diagnosis is needed.

What is “limp mode” in relation to the P2119 code?

Limp mode is a safety feature where the PCM limits engine performance, often locking the throttle to a set position, if a serious problem is detected with the TAC system. This allows you to “limp” the vehicle to a safe location but with very limited speed and power.

Where can I find more information specific to my vehicle for the P2119 code?

Consult the factory repair manual or technical service bulletins (TSBs) for your specific vehicle make, model, and year. These resources will have detailed diagnostic and repair procedures, wiring diagrams, and component locators tailored to your vehicle.
