What does the P0572 code mean?

The P0572 code is related to the brake switch circuit. When this code appears, it means that the powertrain control module (PCM) has detected an open or short circuit in the brake switch circuit. The brake switch is a small device located behind the brake pedal that sends a signal to the PCM when the brake pedal is pressed. This signal is used by the PCM to control various systems, such as the transmission, cruise control, and traction control.

It’s important to understand the P0572 code because if left untreated, it can lead to various issues. For example, the transmission may not shift properly, the cruise control may not work, and the traction control may be disabled.

What causes the P0572 code?

When looking at the reasons behind the code P0572, there are several potential issues that could lead to the code’s activation. We’ve decided to list all of them to try and introduce you to the parts you’ll most likely need to repair or replace to fix the code:

Faulty brake switch

The most common cause of the P0572 code is a faulty brake switch. Over time, the switch can wear out or become misaligned, which can cause it to malfunction.

Wiring issues

Another potential cause of the P0572 code is wiring issues. The wiring that connects the brake switch to the PCM can become damaged or corroded, which can cause a short circuit or an open circuit.

PCM issues

In rare cases, the PCM itself may be the cause of the P0572 code. If the PCM is malfunctioning, it may not be able to properly receive the signal from the brake switch.

Which car models does the P0572 code affect the most?

The P0572 code can affect various car models, but some models are more prone to this issue than others. These models include Honda, Acura, and Toyota vehicles. This is because these vehicles use a specific type of brake switch that is more susceptible to wear and tear. We wanted to take a closer look at this so we can tell you exactly which models are more prone to the code:

• Honda Accord: The Honda Accord has been known to experience issues with the brake switch circuit, including P0572. Some drivers have reported that their brake lights stay on all the time, while others have had issues with the lights not turning on at all.
• Subaru Impreza: The Subaru Impreza is a compact car that has been known to experience issues with the brake switch circuit. Drivers have reported that their brake lights stay on even when they’re not pressing the pedal, and in some cases, the cruise control may not work properly.
• Toyota Camry: The Toyota Camry is another car model that has been known to experience issues with the brake switch circuit. In some cases, drivers have reported that their brake lights stay on even when they’re not pressing the pedal, while in other cases the lights don’t turn on at all.

How to diagnose the P0572 code

There are several ways you can diagnose the code P0572, and they mostly depend on the exact reason behind the code. So, you can apply the following testing methods to see if you can pinpoint the source of the problem that caused the code to show up:

Check the brake switch

The brake switch is a small component located under the brake pedal that senses when the pedal is depressed. A faulty brake switch can trigger the P0572 code. To check the brake switch, you can use a multimeter to test its continuity and resistance.

Take a look at the wiring and connections

The wiring that connects the brake switch to the car’s computer can also be a source of trouble. It’s important to inspect the wiring for any damage, corrosion, or loose connections that may cause an issue with the circuit.

Look for other diagnostic codes

A diagnostic scanner can be used to scan for codes and retrieve any stored codes related to the brake switch circuit. This can help you pinpoint the root cause of the problem.

Perform a visual inspection

A visual inspection of the brake pedal, brake light bulbs, and other related components can reveal any obvious signs of damage or wear that may cause issues with the circuit.

How to fix the P0572 code

Fixing the P0572 code depends on the underlying cause of the issue. So, once you are done with the diagnosis, you can apply one of the following solutions to remove the code:

Replace the brake switch

If the brake switch is faulty, it will need to be replaced. This is a relatively simple and inexpensive fix that can be done without a help of a mechanic, and it usually costs around $50 or up to $100 to replace this component.

Repair the wiring and connections

If there are any wiring issues, they will need to be repaired or replaced. This may require a bit more expertise and the use of specialized tools. This one can be a bit more expensive depending on what exactly needs to be fixed, so the cost may be slightly higher than $100.

Fix the PCM

If the PCM is the cause of the issue, it will need to be replaced. This is a more expensive fix that should only be done by a professional. Since the PCM repair can cost anywhere between $500 and $1000, it’s best to first take a look at other possible reasons just to be safe.

How to prevent the P0572 code

To prevent the P0572 code from appearing, it’s important to properly maintain the brake switch and its associated wiring. Here’s what you can do to prevent the code from re-appearing:

• Checking the brake switch regularly for signs of wear or misalignment.
• Checking the wiring for any signs of damage or corrosion.
• Performing routine maintenance on the brake system, such as replacing brake pads and rotors.

By following these preventative measures, you can help ensure that your vehicle stays in good working order and avoid the hassle of dealing with the P0572 code.

Our take

Overall, the brake switch issue may not seem like that much of a serious problem, but it can affect the performance of your car’s transmission or cruise control system. So, it’s essential to have it fixed ASAP to prevent code P0572 from harming your driving safety even further.

We hope that this guide will be all it takes for you to deal with the code, and make sure to consult a professional if any mechanical components need to be replaced.
