What Does P0236 Trouble Code Mean?
The P0236 trouble code indicates an issue with the turbocharger or supercharger boost sensor A circuit.
This sensor monitors the pressure in the intake manifold and compares it to the expected values. When the sensor detects a discrepancy outside of the acceptable range, the code is triggered.
This code specifically points to a problem with the sensor’s range or performance.
Essentially, it means the sensor is either reading a pressure that is too high or too low compared to what the engine control module (ECM) expects.
This discrepancy can impact the engine’s performance, leading to noticeable issues while driving.
The boost pressure sensor plays a crucial role in managing the turbocharger or supercharger. It ensures that the engine gets the correct amount of air, which is vital for optimal combustion.
When this sensor malfunctions, it can throw off the air-fuel mixture, leading to problems like reduced engine power, poor acceleration, and increased fuel consumption.
In practical terms, if you’re seeing the P0236 code, your vehicle might struggle with maintaining proper power levels.
You might notice that it’s not accelerating as it should, or it feels sluggish. The check engine light will likely be illuminated, and you might also experience engine misfires or stalling.
Addressing this code promptly is important to avoid further damage to your engine. The root cause could range from a faulty sensor or wiring issues to more complex problems like intake manifold leaks or a malfunctioning turbocharger.
Identifying and fixing the underlying issue will help restore your vehicle’s performance and prevent more severe problems down the road.

- Intake manifold leaks
- Faulty engine control module (ECM)
How To Fix A P0236 Trouble Code
Fixing a P0236 trouble code involves a thorough diagnostic process to identify and repair the underlying issue. Here’s how you can address it:
1. Check for Additional Codes
Start by scanning your vehicle’s computer for any additional trouble codes. P0236 often appears with other codes that can help narrow down the problem.
2. Inspect the Turbocharger/Supercharger
This code relates to the turbocharger or supercharger boost sensor. Visually inspect these components for any signs of damage or wear.
3. Examine the Boost Sensor
Locate the boost sensor, also known as the Manifold Absolute Pressure (MAP) sensor. Check for any loose connections, damaged wires, or corrosion. Clean the sensor and connector if necessary.
4. Test the Boost Sensor
Use a multimeter to test the boost sensor’s voltage. Compare the readings with the manufacturer’s specifications. Replace the sensor if it’s not within the correct range.
5. Inspect the Vacuum Lines
Check all vacuum lines connected to the turbocharger or supercharger system for leaks, cracks, or disconnections. Replace any damaged lines to ensure proper airflow.
6. Check the Wastegate
The wastegate controls the turbocharger’s boost pressure. Ensure it’s operating correctly and not stuck open or closed. A faulty wastegate can cause incorrect boost pressure readings.
7. Examine the Intake System
Inspect the entire intake system for any leaks or blockages. This includes the intercooler, intake manifold, and all related hoses and pipes.
8. Test the ECM
If all other components are functioning correctly, the issue might lie with the Engine Control Module (ECM). Check for any updates or reflash the ECM. Replace it if necessary.
9. Professional Diagnosis
If you’re unable to find the problem, consider taking your vehicle to a professional mechanic. They have the tools and expertise to diagnose and repair complex issues.
By following these steps, you can effectively diagnose and fix the P0236 trouble code, ensuring your vehicle’s turbocharger or supercharger system operates correctly again.
Conclusion
Now you know what the P0236 trouble code means and how you can fix it.
