The P0236 code indicates that there is an issue with your “A” circuit for your turbocharger or supercharger. If you have multiple sensors, then this will be whatever your make and model decides is an “A” circuit, which may vary, which is why it’s a good idea to check the manual before you start investigating. It generally signifies that the turbo boost sensor isn’t what the powertrain control module (PCM) would expect compared to the MAP (manifold absolute pressure) sensor or the BARO (barometric pressure sensor).
More About the P0236 Code
The turbocharger, also called a supercharger, is a unique pump powered by the exhaust gasses that the combustion chamber produces. This creates boost pressure, increasing the amount of fuel/air mixture compressed by the piston moving, which creates more power. However, the turbocharger then needs to have certain sensors to ensure it’s doing its job correctly, and this charge indicates that the expected values are not being met.

What Are the Symptoms of a P0236 Code?
The first thing you can expect is that the check engine light will be illuminated, as this code will turn on the check engine light in your vehicle. Outside of that, your symptoms will depend on the actual cause of the problem. The PCM may turn off the turbo boost, which may mean you’ll notice a lack of power when compared to how it usually looks. Additionally, even if the turbo boost is on if the boost sensor doesn’t register the right amount of boost pressure, you may notice that during hard acceleration, you’ll still notice issues with power.
What Are Some Causes of a P0236 Code?
The reason you’ll see this code is that the turbo boost pressure sensor, MAP sensor, and BARO sensors are not all giving the same reading. This can be for a variety of reasons, including issues with the sensor being contaminated or clogged, deteriorated with age, or not connected properly with its various wires. Issues with your vacuum or exhaust lines may also cause this code, as may a defective supercharger or turbocharger itself.
How Serious Is the P0236 Code?
Depending on whether your vehicle will simply turn the turbocharger off, the P0236 code may not be that serious; many vehicles can still technically function without the turbocharger, so its lack of presence may not be especially serious. However, if the vehicle does not turn off the turbocharger, the chance of overboost may become very high, which can be very damaging to your vehicle. Regardless of what vehicle type you think you have, this is a problem that a mechanic can fix fairly easily, so it’s always best to get it checked out. You don’t want to take any chances.
Can I Still Drive with a P0236 Code?
In most vehicles, you will physically be able to drive with the P0236 code, as it doesn’t often trigger a no-start condition. However, this doesn’t mean it’s a good idea to do so. As mentioned, driving with the P0236 code can lead to overboost, which can then lead to damage within your catalytic converter. Assume that this is a very serious problem and get an expert to help so you can avoid all potential damage to your engine.
How Easy Is It to Diagnose a P0236 Code?
There are many, many potential causes for the P0236 code. As a very generic code, this only indicates what your vehicle’s problem is, not where the problem is coming from or how you can solve it. That means the process of diagnosis is entirely up to you, so you might have a difficult time if you’re not used to this component of your engine. Instead, you might want to talk to an expert who can fix the problem for you.
How Difficult Is It to Inspect a P0236 Code?
The inspection process can be fairly difficult for a P0236 code simply because there are so many elements that are necessary to inspect. You may need to check the turbo boost pressure sensor, MAP sensor, BARO sensor, vacuum lines, exhaust lines, and the connections between all of them. This is a lot of work, and you might not have the tools necessary to do it all, even if you’ve been doing DIY work with your vehicle for some time. Instead, talking to an expert can help you find the right solution.
Need Additional Help with Your P0236 Code?
The P0236 code can be very difficult to solve simply due to the number of causes that it can have. There are a wide number of issues that can arise and lead to the P0236 code, and it’s not a very straightforward fix for most DIYers. That’s why an expert can be a great option.
The first step is to find a repair shop in your area. Especially if the turbo boost is still active, finding a local repair shop can help you get your vehicle in to an expert without overboosting.
Additionally, it’s common for these codes to come with other codes as well. With the KBB OBD-II database, you can discover what those codes mean.
