P2441 is a diagnostic trouble code (DTC) for "Secondary Air Injection System Switching Valve Stuck Closed Bank 1". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $70.00. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $30.00 off as a credit towards the repair.

Secondary Air Injection System Switching Valve Stuck Closed Bank 1
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.
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.
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.
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
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
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.
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
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.
