P0241 Fault Code

P0241 OBD-II Trouble Code Short Description

Generic: Turbocharger/Supercharger Boost Sensor "B" Circuit Low

What does trouble code P0241 mean?

The P0241 fault code indicates a problem with the turbocharger or supercharger boost sensor "B" circuit, signaling a low voltage reading from the sensor. The turbocharger or supercharger may be malfunctioning, or there may be an issue with the electrical circuitry of the sensor itself. This can result in reduced engine power and performance.

To diagnose and fix the issue, you should first inspect the electrical connections and wiring of the boost sensor for any loose or damaged components. If everything appears fine, you may need to replace the sensor or have your turbocharger or supercharger inspected and repaired by a professional. Ignoring this problem can lead to more serious engine problems over time.


What are the symptoms of the P0241 code?

Symptoms of P0241 fault code on cars may include:

  • Illuminated check engine light
  • Decrease in engine power
  • Loss of acceleration
  • Turbocharger or supercharger failure
  • Increased fuel consumption
  • Black smoke emitting from the exhaust
  • Engine stalling or hesitation while accelerating.


What causes the P0241 code?

The P0241 fault code indicates that there is a low circuit signal in the Turbocharger/Supercharger Boost Sensor "B". This can be caused by various factors including:

  • Faulty Boost Sensor
  • Damaged or corroded sensor wiring or connectors
  • Faulty turbocharger wastegate
  • Leaks or restrictions in the intake or exhaust system
  • Malfunctioning Engine Control Module (ECM)

It is important to get this issue diagnosed and repaired promptly to avoid potential engine damage and to ensure optimal vehicle performance.

Possible Solutions

How to fix P0241?

To fix the P0241 fault code on your car, follow these steps:

  1. Check the boost sensor wiring and connections for any damages or loose connections. Repair or replace if necessary.

  2. Inspect the boost sensor for any damages or signs of corrosion. Replace if necessary.

  3. Check the turbocharger or supercharger system for any leaks or damages that may be causing low boost pressure.

  4. Inspect the vacuum lines and hoses for any cracks or leaks, repair or replace if necessary.

  5. Clear the fault code using an OBD-II scanner and test drive the car to make sure the issue has been resolved.

If the fault code persists after following these steps, it may be a sign of a more serious issue with your car's turbocharger or supercharger system, and it's best to consult a professional mechanic.


  • What does the P0241 error code mean?

    The P0241 error code means that there is a problem with the circuit in the turbocharger or supercharger boost sensor that is causing the voltage to be too low.

  • What are some symptoms of a P0241 error code?

    Some symptoms of a P0241 error code include reduced engine power, poor acceleration, and poor fuel efficiency.

  • What causes a P0241 error code?

    A P0241 error code can be caused by a faulty boost sensor, a damaged wiring harness, or a problem with the turbocharger or supercharger system.

  • How is a P0241 error code diagnosed?

    A P0241 error code is diagnosed using a scan tool to check for any stored error codes and by testing the boost sensor and related components using a multimeter and other diagnostic tools.

  • How is a P0241 error code fixed?

    A P0241 error code is fixed by repairing or replacing any damaged components in the boost sensor circuit, such as the sensor itself, the wiring harness, or the connector.

  • Can a P0241 error code cause damage to my vehicle?

    While a P0241 error code is unlikely to cause immediate damage to your vehicle, it can lead to reduced engine power and poor fuel efficiency if left untreated.

  • Is it safe to drive with a P0241 error code?

    While it may be safe to drive with a P0241 error code, you may experience reduced engine power and poor acceleration, which can be dangerous in certain driving situations.

  • Can a P0241 error code be prevented?

    A P0241 error code can be prevented by regularly maintaining your vehicle's turbocharger or supercharger system and by ensuring that the sensor and related components are in good condition.
