P2441 code definition

Secondary Air Injection System Switching Valve Stuck Closed Bank 1

What the P2441 code means

P2441 is an OBD-II code for the engine control module (ECM) detecting no exhaust pulse while monitoring the exhaust pressure sensor when the bank 1 switching valve is commanded to be open with the engine running. This will signal a fault in the system.

What causes the P2441 code?

  • The engine control module (ECM) monitors the exhaust pressure sensors to determine if the air injection system for bank 1 is operating correctly when it commands the switching valve open and closed.

  • The code is set when the air injection system switching valve for bank 1 is commanded open and the sensor is detecting no exhaust pulse indicating the valve is stuck closed or the pressure sensor is defective.

What are the symptoms of the P2441 code?

  • The Check Engine Light will be illuminated and the code P2441 will be set in ECM memory.

  • The vehicle will not run any different in most cases, but you may have an exhaust leak at the switching valve.

  • The vehicle will fail emission testing and exhaust fumes may get into the cab.

How does a mechanic diagnose the P2441 code?

  • Scans for codes and documents the code in the ECM, and then looks at the freeze frame data for the problem.

  • Clears the codes and retest to verify the code returns and two drive cycles

  • Tests the resistance of the bank one switching valve and check as per pinpoint test

  • Tests wiring for shorts between power supply and the pressure sensor

  • Tests the pressure sensor for proper resistance following the pinpoint test for repairs needed

Common mistakes when diagnosing the P2441 code?

  • Clearing ECM memory codes before checking the freeze frame data for the main failure problem, so the failure may be duplicated and repaired

  • Failing to clear the ECM codes after the codes are fixed

  • Failing to verify the failure before attempting testing and repairs

  • Not repairing any exhaust leaks that may cause the code to be present

How serious is the P2441 code?

Code P2441 is an indication that the air injection system switching valve is not working or a sensor problem that will cause no drive symptoms. The exhaust emissions will be affected and will cause the vehicle to fail emission testing. There may also be exhaust leaks that would cause the code to be present.

What repairs can fix the P2441 code?

  • Replacing the air control valve for the secondary air injection system bank one

  • Replacing the exhaust pressure sensor to the secondary air injection system for bank one

  • Repairing wiring or connections to the air injection system as directed by pinpoint tests

  • Repairing any exhaust manifold or pipe leaks in the system

Additional comments for consideration regarding the P2441 code

Code P2441 is for the secondary air injection switching valve being stuck closed for bank one of the engine with the exhaust possibly melting the valve causing it to stick closed. Make sure you correct any engine lean condition or exhaust leaks in the manifold that could cause the exhaust to become hotter than normal.
