Secondary Air Injection System Pump Stuck Off Bank 1

What the P2445 code means

The secondary air injection system is designed to pump outside air into the exhaust in order to help reduce harmful emissions. This trouble code indicates that the powertrain control module has detected a malfunction with this system on the bank 1 side of the engine.

What are the causes of the P2445 code?

The most common cause of this trouble code is a failed air injection pump. The air injection pump is designed with a check valve inside which only allows air to flow in one direction, preventing exhaust gases from escaping through the air pump and only allowing air to enter. When this check valve fails, moisture is able to get inside the air pump.

During the winter months this moisture can freeze, causing the air pump to seize up and possibly break. Other possible causes of this issue would include damaged wiring or connectors associated with the air pump, blown fuses, or a broken serpentine belt.

What are the symptoms of the P2445 code?

Symptoms of this trouble code that the driver may experience would include:

  • Abnormal noises resulting from the failed air pump
  • A Check Engine Light
  • The engine may stumble or hesitate upon acceleration

How does a mechanic diagnose the P2445 code?

A mechanic may diagnose this trouble code by checking the condition of the serpentine belt and the secondary air injection pump for any noises. If no noises are heard, the mechanic would then check the electrical connectors and wiring associated with the air pump. Next, the mechanic would check for any blown fuses. In the unlikely event that no issues are found after all of these tests have been performed, the powertrain control module would be tested for proper function using the manufacturer’s suggested procedure. After the diagnostic is complete, the mechanic would relay all information over to the customer to make a repair decision.

Common mistakes when diagnosing the P2445 code

A common mistake that can be made when diagnosing this issue is to remove and bypass the secondary air injection pump. The vehicle was not intended to run without this air pump and could potentially run poorly if it has been removed or bypassed. Many people remove the air pump and purchase a smaller serpentine belt to bypass it. This is not a good idea and this issue should be repaired properly by a qualified professional.

How serious is the P2445 code?

This trouble code is considered moderately serious. This is due to the fact that it can cause the engine to hesitate or stumble during acceleration. Any trouble code that causes drivability issues is not something to overlook. This is something that should be dealt with as soon as possible to prevent engine damage.

What repairs can fix the P2445 code?

Additional comments regarding the P2445 code

It is important to note that the secondary air injection pump runs any time the engine is running. This means that if the pump is noisy, the noise will get worse as engine speed increases. This can cause overheating of the air pump which can potentially cause further damage to the electrical portion of the air pump system.
