Can You Drive With a Faulty Boost Pressure Sensor? All you need to do is disconnect the battery, then unplug the electrical connector and remove the bolt holding the sensor on.įrom there, bolt the new sensor in, plug it in, and reconnect the battery! If the boost pressure sensor was the problem, you should be good to go now. But while you’re not going to save a ton of money, replacing the boost pressure sensor yourself is typically fairly straightforward. The average boost pressure sensor costs over $125. If you’re looking to replace this sensor yourself to save a little money, you can, but most of the cost is in parts, not labor. However, this cost can vary depending on the vehicle you drive and where you take it for repairs. The average boost pressure sensor replacement cost is between $175 and $200. However, when it comes to finding and accessing the boost pressure sensor, it’s one of the easier components on most vehicles. While this is a fairly straightforward location near the top of the engine, you might need to remove a few components to gain access to it. This area allows it to record the boost that the supercharger or turbocharger is creating without getting in the way of anything. It can also be located on the intake manifold on some car models. Your vehicle’s boost pressure sensor is usually located on the boost pipes between the intake manifold and the turbocharger. Moreover, it acts as a way to protect the rest of the engine if the supercharger or turbocharger stops functioning the way it’s supposed to. This lets the ECM know what’s actually happening to optimize the fuel-to-air ratio for optimal performance.
That’s where the boost pressure sensor comes in. While the ECM requests a specific amount of boost, it needs to measure the result of its request. Your vehicle’s boost pressure sensor tells the ECM how much boost the turbocharger or supercharger is actually producing. If you see that the pressure is lower or higher than usual on higher loads, it can absolutely be caused by a bad boost pressure sensor. Some car models do actually have a turbo pressure gauge which you can read to find the current turbo pressure. This is caused by an increased or decreased turbo pressure. Decrease or Increase in Boost PressureĪs we discussed in the previous symptoms section, a faulty boost pressure sensor can cause the engine performance to increase or decrease. This can be fatal for your engine, so you do absolutely want to address this issue as fast as possible. In some rare cases, it can also increase the turbo pressure, which can cause the performance to increase. However, with a turbocharged engine, it might cut the turbo off completely, which will cause a significant drop in engine performance. That’s because even with a supercharged engine, the ECM doesn’t know how the supercharger is performing, so it can’t optimize performance. This will cause an overall decrease or increase in engine performance.Ī faulty boost pressure sensor will cause more noticeable drops in performance in a turbocharged engine than in a supercharged one, but drops in engine performance can happen in both. Your boost pressure sensor tells your ECM the actual output of your turbo or supercharger, so if it’s not reporting accurate numbers, the ECM will adjust to faulty readings. If there is an underlying issue, your boost pressure sensor is doing precisely what it’s supposed to – alerting you of an underlying problem.
You’ll still need to rule out an underlying electrical issue, and you’ll need to verify that there’s nothing wrong with your turbo or supercharger. If you have this engine code, there’s a good chance that you have a faulty boost pressure sensor, but it’s not the only thing that could be causing it.

More specifically, you’re going to have a code P0236. If you have a faulty boost pressure sensor, you’re going to have a check engine light. If you are interested in a closer look at these signs, here is a more detailed list of the signs of a bad or failing boost pressure sensor to look for: 1. If your car is equipped with a boost pressure gauge, you can also see if the boost pressure has increased or decreased. The most common symptoms of a bad or failing boost pressure sensor are reduced or increased engine performance and a check engine light on your dashboard.
