Secondary Air Injection System Pump Stuck off Bank 2
P2447 is an OBD-II generic code for the engine control module (ECM) detecting the bank 2 secondary air injection pump stuck in the off position when it is commanded on.
The engine control module (ECM) monitors the secondary air injection pump circuits and has detected the pump for bank 2 is not turning on when commanded on.
The code is set when the air injection system pump for bank 2 will not turn on and is stuck in the off position.
The vehicle will not run any different in most cases. Here are some possible symptoms that may occur:
The Check Engine Light will be illuminated and the code is set in ECM memory as a fault.
The exhaust may not burn off excessive fuel without the air pump working and may clog the exhaust catalyst faster.
The vehicle will fail emissions tests.
Scans for codes and documents the code in the ECM, and then look at the freeze frame data for the problem before clearing the codes and retesting
Clears the codes and retest to verify the code returns
Scans and monitor pump when commanded to turn on to see if the pump runs
Tests the air pump to see if it is getting power and ground as per pinpoint tests
Tests wiring for shorts between power supply and the pump
Tests the pump for proper resistance following pinpoint test
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
Code P2447 is an indication that the air injection system pump for bank 2 is not working. The exhaust emissions will be affected and will cause the vehicle to fail emission testing. The lack of added air to the exhaust stream will cause the catalyst to get sooted up quicker and will be harder to get burned off. This may lead to a clogged catalyst.
Replacing the air pump for the secondary air injection system bank 2
Replacing the secondary air injection system pump relay
Repair wiring or connections to the air injection system as directed by pinpoint tests
Code P2447 is for the secondary air injection pump for bank 2 and the exhaust potentially being clogged from too much soot build up on the catalyst on that side of the engine. This can cause a loss of power in some cases. The catalyst may have to be replaced after the pump is repaired if it cannot be cleared of soot.
