BMW P1419 Code:Secondary Air System Air Mass Flow Sensor Disconnected or Stuck Signal
As a BMW owner, it can be frustrating to see a warning light pop up on your dashboard. One of the most common issues that BMW drivers face is the P1419 diagnostic trouble code (DTC). This code is related to the secondary air system air mass flow sensor being disconnected or stuck, which can cause a range of symptoms and affect the performance of your vehicle. In this article, we will explore the meaning, causes, symptoms, and fixes for the BMW P1419 code, so you can get your BMW back on the road in no time.
Understanding BMW P1419 Code
The BMW P1419 code is a diagnostic trouble code (DTC) that indicates a problem with the secondary air system air mass flow sensor. This code is triggered when the sensor is either disconnected or stuck in a particular signal. The secondary air system is responsible for reducing emissions by injecting fresh air into the exhaust system during cold starts. When the air mass flow sensor fails, it can cause a variety of issues, including reduced engine performance, increased emissions, and even engine damage. It is important to address this issue promptly to avoid further damage to your BMW.
Signs and Symptoms of BMW P1419 Code

This can cause a variety of symptoms that can affect the performance of your BMW. Here are some of the signs and symptoms you may experience if your BMW has a P1419 code:
- Check Engine Light: The most common symptom of the P1419 code is the check engine light coming on. This light will illuminate on your dashboard to indicate that there is a problem with your BMW’s secondary air system.
- Reduced Power: Another symptom of the P1419 code is reduced power. Your BMW may not accelerate as quickly or smoothly as it normally would, and you may notice a decrease in overall performance.
- Engine Misfires: If your BMW has a P1419 code, you may experience engine misfires. This can cause your engine to run rough or stall, and you may notice a decrease in fuel efficiency.
- Strange Noises: You may also hear strange noises coming from your BMW if it has a P1419 code. These noises can include hissing, popping, or whistling sounds, and they may be more noticeable when you accelerate or decelerate.
- Smell of Gasoline: If your BMW has a P1419 code, you may also notice a strong smell of gasoline. This can be a sign that your engine is running too rich, which can cause damage to your catalytic converter over time.
If you experience any of these symptoms in your BMW, it is important to have your vehicle inspected by a qualified mechanic as soon as possible. Ignoring the P1419 code can lead to further damage to your engine and other components, which can be costly to repair. By addressing the issue early on, you can save yourself time, money, and frustration in the long run.
Possible Causes of BMW P1419 Code
The P1419 code in BMW vehicles is related to the secondary air system air mass flow sensor. This code indicates that the sensor is either disconnected or stuck in a signal. There are several possible causes of this issue, including:
- Faulty air mass flow sensor: The air mass flow sensor may be faulty, causing it to send incorrect signals to the engine control module (ECM).
- Disconnected or damaged wiring: The wiring that connects the air mass flow sensor to the ECM may be disconnected or damaged, causing a loss of signal.
- Failed ECM: The ECM may have failed, causing it to not receive signals from the air mass flow sensor.
- Blocked air intake: The air intake may be blocked, preventing air from entering the engine and causing the air mass flow sensor to send incorrect signals.
- Failed air pump: The air pump may have failed, preventing air from entering the engine and causing the air mass flow sensor to send incorrect signals.
- Failed air control valve: The air control valve may have failed, preventing air from entering the engine and causing the air mass flow sensor to send incorrect signals.
It is important to note that the P1419 code may also be triggered by other issues, such as a failed oxygen sensor or catalytic converter. Therefore, it is recommended to have a professional mechanic diagnose the issue to ensure the correct repair is made.
In summary, the possible causes of the BMW P1419 code include a faulty air mass flow sensor, disconnected or damaged wiring, a failed ECM, a blocked air intake, a failed air pump, and a failed air control valve.

Fixes for BMW P1419 Code
The P1419 code in BMW vehicles indicates a problem with the secondary air system air mass flow sensor, which may be disconnected or stuck. This can lead to a variety of symptoms, including reduced engine performance, increased emissions, and even engine damage if left untreated. Fortunately, there are several fixes that can address this issue and get your BMW back on the road.
- Check the air mass flow sensor: The first step in fixing the P1419 code is to check the air mass flow sensor for any signs of damage or disconnection. This sensor is responsible for measuring the amount of air entering the engine, and if it is not functioning properly, it can cause the engine to run poorly. If the sensor is damaged or disconnected, it will need to be replaced or reconnected.
- Inspect the air injection system: The secondary air injection system is another potential source of the P1419 code. This system injects air into the exhaust system to reduce emissions, and if it is not functioning properly, it can cause the air mass flow sensor to malfunction. Inspect the air injection system for any signs of damage or blockage, and replace any faulty components as needed.
- Clean or replace the air filter: A dirty or clogged air filter can also cause the P1419 code to appear. This is because a dirty air filter restricts the flow of air into the engine, which can cause the air mass flow sensor to malfunction. Clean or replace the air filter to ensure that air is flowing freely into the engine.
- Check the vacuum lines: The vacuum lines that connect the air injection system to the engine can also cause the P1419 code to appear if they are damaged or disconnected. Inspect the vacuum lines for any signs of wear or damage, and replace any faulty lines as needed.
- Reset the engine control module: In some cases, simply resetting the engine control module (ECM) can clear the P1419 code. This can be done using a diagnostic tool or by disconnecting the battery for a few minutes. However, if the underlying issue is not addressed, the code is likely to reappear.
How Much Will It Take to Fix BMW P1419 Code?
The cost of fixing the BMW P1419 code can vary depending on the root cause of the issue. In some cases, it may be a simple fix that can be done at home, while in other cases, it may require professional assistance and expensive parts replacement.
If the issue is caused by a disconnected air mass flow sensor, it may be a simple fix that can be done at home. However, if the sensor is stuck or damaged, it may need to be replaced, which can cost anywhere from $100 to $500, depending on the make and model of your BMW.
