P1415 Code: Secondary Air Injection System (GM, Bank 1)

On General Motors vehicles (Chevrolet, GMC, Buick, Cadillac), the P1415 code means the secondary air injection system on bank 1 is not working as expected. You may hear the air pump after a cold start, or notice that it stays silent. Other brands may use this number for something else.

What the P1415 code means

P1415 is a manufacturer-specific code: the 1 in the second position means each automaker defines what it means, not the generic SAE standard. The most widespread definition is the one used by General Motors (Chevrolet, GMC, Buick, Cadillac). If your vehicle is another brand, confirm the code text with a scan tool that supports that manufacturer.

ManufacturerMeaning of P1415
General Motors (Chevrolet, GMC, Buick, Cadillac)Secondary air injection system (bank 1)

The GM secondary air system blows air into the exhaust after a cold start to warm up the catalytic converter faster.

The computer sets the P1415 code when, with the pump running, the bank 1 oxygen sensor does not detect the extra air. The pump, the valve or an air passage may be blocked.

Before you start repairs, confirm the make, model, year and engine. With manufacturer codes, the same number can change even between engines from the same brand.

P1415 code symptoms

  • Check engine light on.
  • Air pump noise after a cold start, or no noise at all when you expect it.

Likely causes of the P1415 code

  1. Stuck check valve or shutoff valve.
  2. Air pump failed from moisture getting into it.
  3. Air passages to the exhaust manifold blocked. Confirm it with the tests in the diagnosis section.
  4. Relay or fuse. Swap it with an identical one to rule it out.

How to diagnose the P1415 code step by step

  1. Start the engine cold and listen for the pump. It should run for a short time right after startup.
  2. Turn the pump and the valve on with the scan tool and watch whether they respond.
  3. Watch the oxygen sensor. It should read lean while the air is active.

How to fix the P1415 code

  • Replace the valve or the pump.
  • Clean the air passages.

Technical reference data

  • The pump runs for 30 to 90 seconds after a cold start.
  • P1xxx codes are manufacturer-specific: confirm the definition with a scan tool that supports your brand.
  • Reference values: check the manufacturer data for your vehicle.

Brand-specific notes

A cold start is the best time to test this system, because that is the only time the pump normally runs.

P1415 on GM

Common on the Chevrolet Silverado, Tahoe, Suburban and Corvette.

If your vehicle is another brand, check the table above for the meaning its manufacturer gives this code and confirm it with a compatible scan tool.

Frequently asked questions about P1415

What does the P1415 code mean on a GM?
It means the secondary air injection system on bank 1 is not working as expected. You may hear the pump after a cold start, or notice that it does not run.
Does P1415 mean the same thing on every brand?
No. It is a manufacturer-specific code, so on other brands it may not exist or may mean something different. Confirm it with a scan tool that supports your make.
Can I drive with a P1415 code?
Yes. With a P1415 code the severity is low and the vehicle normally drives as usual. You may fail an emissions test until it is repaired.
How much does it cost to fix P1415?
Roughly $80 to $700 on a GM. A relay or a cleaned passage is cheap, while a new air pump or valve costs more.
Will a P1415 code clear itself?
Not while the pump, valve or passage fault is still there. After a repair, clear the code and do a cold start to confirm it stays off.
What is the most common cause of P1415?
A stuck check or shutoff valve and a pump damaged by moisture are the usual causes. Blocked passages to the manifold come next.
