P2262 code 6.7 Cummins: Turbocharger / Supercharger Boost Pressure Not Detected.

P2262 code 6.7 Cummins indicates “Turbocharger/Supercharger Boost Pressure Not Detected.” This DTC applies to vehicles equipped with OBD-II. This includes most post-1996 models.

Your car’s powertrain control module (PCM) contains several sensors that monitor how much power the turbocharger/supercharger produces. Code P2262 can be entered when your PCM detects the boost pressure is not reaching its minimum level.

It should be noted that the interpretation of code P2261 may vary depending on the vehicle manufacturer. Check the correct maintenance instructions or the maintenance database for the exact definition of the code.

What are the possible causes of the P2262 code 6.7 cummins?

Code P2262 was detected during vehicle inspection. A problem with the supercharger/turbocharger boost pressure was not seen – a mechanical problem. This problem occurs when your engine control module (ECM) detects a difference between actual and expected turbocharger boost. The reason for code P2262 is:

  • The turbocharger or Supercharger could be defective or damaged.
  • It could be a problem with the mechanical part of this boost sensor.
  • In the exhaust system, leaks, specifically in the manifolds or pipes, may cause this code to occur.
  • Intercooler tubes that are damaged or blocked can cause the code P2262.
  • The code could be triggered due to problems with the Wiring or connections to your boost sensor.
  • It’s essential to address these issues quickly, as they can significantly impact your vehicle’s performance.

What are the Common Symptoms of the P2262 Code?

A decrease in motor power. The most noticeable sign of the P2262 code is a drastic decrease in the engine’s power. The vehicle may be lagging when it is in acceleration.

Poor fuel economy: When the engine tries to increase power, it will consume more fuel than usual, resulting in low fuel efficiency.

The Check Engine Light: The Check Engine Light typically illuminates when the P2262 code is activated.

Strange sounds: Whistling or whining from the turbocharger or exhaust could be heard if a mechanical issue is causing the P2262 error code.

Smoke from the exhaust: In certain instances, the vehicle could produce more fumes than usual from its exhaust. This could indicate an issue with the exhaust system.

How to Diagnose the P2262 Code

Scanning and document Documentation: The initial step is to scan the vehicle using a professional OBD-II scanner. The freeze frame information and the other related fault codes must be documented to aid in future reference.

Visual Inspection: Do an exhaustive visual examination of the turbocharger as well as the intercooler, exhaust, and tubes. Examine for any obvious evidence of damage, leaks, or obstructions.

Check the Wiring and connectors: Check the connections and Wiring that connect to the pressure sensor for boost. Any indications of damage, corrosion, or loose connectors need to be dealt with immediately.

Test Drive: Following the visual Inspection and any initial repairs (if there are any), clean all diagnostic codes and then take the vehicle out for an initial test drive. While there, observe whether you see the Check Engine Light reappear or any other symptoms occur.

The Pressure Test: If the issue persists, you should conduct a turbocharger pressure test to find any damages or leaks in the engine that were not evident in the initial examination.

Professional Inspection: If the problem isn’t resolved, seek help from a professional. A qualified mechanic may employ advanced diagnostic tools and skills to identify the main reason for the P2262 error.

Be aware that these steps might not be required in all cases. The method of diagnosis can differ according to how the symptoms manifest and the specific model and make of the car.

How to Fix the P2262 Code

The fix for the P2262 code requires a systematic approach that addresses the causes that could be causing this troublesome diagnostic code:

Replace the damaged turbocharger and Supercharger: If there is a malfunction or damage on the turbocharger or in its Supercharger, it is recommended to replace it if needed. This is a lengthy procedure that may require expert assistance.

Repair Mechanical issues within the Boost Sensor: If a mechanical issue is discovered inside the boost sensor, it must be fixed promptly. It could involve either repair or replacement.

Leaks in the Seal exhaust system: Leaks found inside the exhaust systems, especially within the manifold or pipes, should be fixed immediately. Depending on the severity of the leak, this could include welding, sealing, or even parts replacement.

Remove or clean the intercooler Tubes: If the intercooler tube is damaged or blocked, the tubes must be cleaned or replaced to ensure proper airflow.

Fix or replace Connectors and Wiring: If there are any problems with the Wiring or connectors connected to the boost sensor, they need to be fixed. This could involve Wiring, soldering, or a replacement connector.

Remember that If you notice that the Check Engine Light reappears with P2262 codes after fix or replace, it’s advised to conduct a second diagnostic and follow repair steps for a second time. If nothing else works, seek out a qualified mechanic. The mechanic will identify and correct the problem to protect the vehicle against further harm while keeping its performance.


What does the diagnostic trouble code mean?

The P2262 diagnosis trouble code indicates a difference in the turbocharger’s or supercharger’s boost pressure.

What are the most common signs of the code P2262?

The most common symptoms are lower engine power, poor performance and illumination of the Check Engine Light, unusual sounds, and a lot of smoke coming from the exhaust.

How do you identify the code P2262?

Recognizing P2262 code P2262 code is as simple as checking the vehicle’s diagnostics with an OBD-II scanner, a visual inspection of the turbocharger as well as the intercooler and exhaust tubes, testing connections and Wiring, using the car, conducting an examination of the pressure in the turbocharger and possibly seeking assistance from a professional.

What are the most common solutions for the code P2262?

A4 Common fixes are replacing a defective turbocharger or Supercharger. They also fix mechanical problems in the boost sensor or sealing leaks within your exhaust system, remove or replace damaged or blocked intercooler tubes and replace damaged connections and Wiring.

What happens if the P2262 code reappears following repairs?

If the P2262 code appears after repair, it’s recommended to go through the diagnostic process again and follow the repair procedure again. If the repair fails, you need to consult a professional mechanic.


The P2262 diagnostic trouble code is a significant issue that can significantly affect the performance of your vehicle’s performance and fuel efficiency. The law specifies an unbalanced turbocharger or supercharger boost pressure, with possible causes ranging from a faulty turbocharger and leaks in the exhaust system to damaged intercooler hoses and problems with connectors or Wiring. The process of diagnosing and fixing this problem must be comprehensive that is systematic, and thorough, starting from drawing and scanning to advanced procedures such as stress testing or Inspection by a professional engineer, Fixing the problem quickly and correctly is essential because neglecting it can cause severe damage to your vehicle and severely impair the performance of your car.
