The definition of code P0035 indicates that your Powertrain Control Module (PCM) or Engine Control Module (ECM) is showing a high or shorted circuit for a boost pressure control valve. In a turbocharged vehicle, the pressure bypass control valve allows the engine to relieve pressure when necessary. However, if the bypass system has an issue turning on, it can impact the supercharger. This code indicates that Valve A, which may only be one of the bypass valves in your system, is too high, which can indicate that the bypass valve is not relieving boost pressure when it should.
More About Error Code P0035
The P0035 trouble code will have a slightly different definition for each manufacturer, make, and model, as different vehicles may have different turbocharger or supercharger designs. For example, this code may indicate a specific bypass valve or a specific issue within the bypass valve. This is one reason it’s so important to have specific knowledge of your vehicle, as even generic OBD-II powertrain codes can vary slightly between vehicles. Your automotive repair skills may not include the detailed factory repair information often required for non-common repairs like the P0035 code.

What Are the Symptoms of a P0035 Code?
When your vehicle logs a P0035 diagnostic trouble code, you will see a check engine light turn on, which may be your first sign that something is wrong. On top of that, you’ll likely see a lack of engine performance and fuel efficiency in your vehicle caused by the lack of boost from the turbocharger or supercharger. While it may seem like a fairly small issue due to its impact being restricted to the turbocharger, this is critical to your vehicle’s function. Sometimes, it may cause your vehicle to enter Limp Home mode. This drivability issue can shut down many of the performance features you expect from your vehicle, such as air conditioning.
What Are Some Causes of a P0035 Code?
Actual defective engine components are common here. The bypass valve for the turbocharger or supercharger is often the problem with the P0035 fault code, as it may be faulty in some way, with an internal failure causing a closed position. Circuit issues can also cause the P0035 code, ranging from damaged wires to poor connections between the vehicle parts. In some rare cases, the problem might lie with PCM issues, including anything from faulty PCM parts to a software update that hasn’t been pushed through.
How Serious Is the P0035 Code?
The P0035 engine code is generally extremely serious. As previously indicated, the turbocharger and supercharger systems help your vehicle accelerate, so you’ll use them every time you press the gas pedal. Problems can lead to fuel injector malfunction, creating a lean fuel mixture, or some other incorrect air/fuel mixture type. Vehicles with this type of code should get help immediately. They can result in severe internal engine damage over a very short period, so you must get help as soon as possible.
Can I Still Drive with a P0035 Code?
You should avoid driving with the P0035 engine misfire code. First, driving will be frustrating if the vehicle is in Limp Home mode. This mode can limit the maximum speed of your vehicle to 40 MPH or lower, turn off “unnecessary” systems like your vehicle’s air conditioning or power doors, and generally make it difficult to drive overall. Second, if you continue to drive, you run the risk of causing major engine damage, and a follow-up repair for the engine is much more expensive than the P0035 sensor code.
How Easy Is It to Diagnose a P0035 Code?
Diagnosis of the P0035 generic code can sometimes be simple if it’s the first thing you’re looking for. If your problem is a faulty turbocharger bypass valve, that will probably be the first thing you identify and likely be an easy fix. However, problems can arise if it’s not the turbocharger bypass valve or if you overlook the problem in this valve, both common mistakes for beginners. This is especially true if it seems like an intermittent issue. You may need specialized knowledge of how the vehicle works, so it’s best to hand it over to an experienced mechanic.
How Difficult Is It to Inspect a P0035 Code?
The inspection process for this complicated code can also be difficult. Many experts will have specialty scan tools to let them know more about what’s going on in the vehicle while driving it, which you might not have access to. Additionally, you must know how to inspect the vehicle safely without causing more serious engine damage. You’ll also want to know how to tell what part of the vehicle has a problem, an issue that isn’t always easy for DIYers. This is why most people opt for certified mechanics to deal with these error codes.
Need Additional Help with Your P0035 Code?
