P2241 Fault Code

O2 Sensor Positive Current Control Circuit Low Bank 2 Sensor 1

• What does that mean?
• Symptoms
• Causes
• Solutions

• The P2241 fault code indicates a problem with the oxygen (O2) sensor positive current control circuit for Bank 2 Sensor 1. This sensor is crucial for measuring the amount of oxygen in the exhaust gases, allowing the engine control unit (ECU) to adjust the air-fuel mixture for optimal combustion.
• Proper functioning of this sensor helps in maintaining efficient engine performance and reducing emissions.

What are the symptoms of the P2241 code?

• Drivers may notice symptoms such as:
  • Decreased engine performance or reduced fuel efficiency.
  • The check engine light illuminated on the dashboard.
  • Potential failures during emissions testing due to improper readings from the O2 sensor.

What causes the P2241 code?

• A low voltage or faulty connection in the positive current control circuit for the O2 sensor can lead to this fault code.
• Potential causes may include:
  • Damaged wiring or connectors in the sensor circuit.
  • A malfunctioning Bank 2 Sensor 1 O2 sensor itself.
  • Issues with the engine control unit (ECU) or its programming.

How to fix P2241?

• To resolve the P2241 code, consider the following steps:
  • Inspect the wiring and connectors leading to the Bank 2 Sensor 1 O2 sensor for any signs of damage or corrosion.
  • Test the O2 sensor for proper operation and replace it if necessary.
  • Verify the ECU’s programming to ensure it is functioning properly with the sensor.
  • Clear the fault code and conduct a test drive to confirm that the issue has been resolved.
