The P057C code definition is “Brake Pedal Position Sensor A Circuit Low.” This code indicates that your vehicle’s powertrain control module (PCM) or engine control module (ECM) has indicated that the circuit for the brake pedal position sensor A is not returning the recommended level of voltage according to the manufacturer’s specifications. Although this is a generic powertrain code and can show up in many different vehicles, it is most commonly reported with Chevy vehicles.
More About the P057C Code
Your vehicle’s brake pedal position sensor allows the PCM to know how much you’re braking. It senses how far you’re depressing the brake pedal, which ensures that when you brake, the car stops consistently the more you press the brake. However, it relies on circuits that provide power to the component, which allows it to send these messages. This code indicates that your vehicle has identified an issue with a low reference voltage from the position sensor, which can mean that it isn’t able to transmit information effectively.

What Are the Symptoms of a P057C Code?
There are many possible symptoms of the P057C code, ranging from being unable to brake as effectively to having your brake lights on all the time. This partially depends on how the brake pedal sensor has failed and whether it’s generally identifying your vehicle as braking more or less frequently than you actually are. In some cases, there may not be any symptoms related to brake pedal input, and you may just see it as a check engine light code.
What Are Some Causes of a P057C Code?
The main causes of a P057C code usually have to do with the brake position sensor itself. Oftentimes, this diagnostic trouble code occurs because of issues with a faulty brake pedal sensor. If this isn’t the problem, it’s usually wiring issues, including concerns with the wiring harness and grounding on the wiring to the brake pedal position sensor circuit. If you’re having problems with the brake sensor circuit, you may need to check multiple connections to determine the core problem.
How Serious Is the P057C Code?
The P057C brake pedal sensor code is quite serious. After all, anything having to do with your brake switch circuit can lead to severe issues when driving; whether your vehicle is consistently braking to some extent or doesn’t register your braking, it can have serious repercussions on your safety. Whether you’re worried about your ability to brake or the health of your brakes overall, it’s important to treat the P057C code as a serious problem.
Can I Still Drive with a P057C Code?
You may physically be able to drive with the P057C code active, depending on the extent of the code. In some cases, the voltage may be so low that your brake pedal no longer works as well, which can make it more difficult to navigate with your vehicle. Additionally, other systems may be negatively impacted; you may not be able to shift the car from the park position and Advanced Driver Assist Functions may be disabled. These problems could cause you to no longer physically be able to drive with this code. However, even if you are able to drive, it’s not a great idea to continue to drive anyway. This is because these more severe problems can kick in at any time, potentially causing a serious safety hazard.
How Easy Is It to Diagnose a P057C Code?
If you’re dealing with a faulty brake pedal position sensor, the diagnosis process may be somewhat simple. However, in other situations, there may be significantly more work necessary for an effective diagnosis. Even if your problem is an issue with the brake pedal position sensor itself, you will likely need to go through a diagnostic process to determine the core issue and whether or not you can fix it by replacing the part. Generally, you can’t rely on a quick question and answer from sites on the internet; it’s best to rely on the qualifications of experts who understand the process of fixing the problem.
How Difficult Is It to Inspect a P057C Code?
Inspecting a P057C code is often a bit difficult. There are a number of different things that can fix the P057C problem, ranging from slightly simpler fixes to slightly more complicated ones. Whether you need to perform a relearn procedure with your brake system or you’ve just installed aftermarket third-party service products that are causing the issue, the inspection process can be difficult. That’s why many people choose to rely instead on the highly-rated, verified experts at their local auto repair shop rather than trying to handle the code on their own.
Need Additional Help with Your P057C Code?
If you need extra help with your P057C code, you’re definitely not alone. This is a process that can be difficult to understand, especially because professional advice regarding this code can be quite difficult to find when asking questions from readers online. Instead, consider seeking professional advice from an expert so you can be sure that the problem ends up being fixed.
Your first step should be to find an auto repair shop in your area. Finding a local auto repair shop is a great way to get a fix for the problem without having to go too far out of your way. Plus, if you’re dealing with issues surrounding driving your vehicle, a local repair shop means you don’t have to pay much for a tow truck to get help from qualified professionals.
If your scan tool is showing more than just this code, which is common, it may also be a good idea to check out the OBD-II database at KBB.com. This database can help you determine what you might expect from a fix before you actually bring your vehicle in.
