What is P1415 : Engine Error code Causes Explained
The P1415 engine trouble number indicates a secondary air injection system malfunction that may impair emissions and performance. Understanding its causes, symptoms, and solutions might speed up diagnosis and treatment.
How to Identify a DTCs Number
The Diagnostic Trouble Code (DTC) P1415 is related to the Secondary Air Injection (SAI) system, specifically indicating an issue with the bank 1 air system.
Understand, this trouble codes (DTCs) are 5 characters: 1 letter, 4 numbers. P-Powertrain indicates the fault code’s location. Generic or manufacturer-specific codes are indicated by the first digit. The second digit denotes the subsystem (7=transmission). The last two numbers describe the issue.
This error typically occurs when the Engine Control Module (ECM) detects that the expected airflow from the secondary air pump is not reaching the exhaust system as intended.
Causes of P1415 Code:
- Faulty Secondary Air Injection Pump:
The pump may fail due to age, water intrusion, or electrical issues. - Wiring or Connector Issues:
Damaged or corroded wires or connectors in the secondary air injection circuit. - Malfunctioning Air Injection Check Valve:
A stuck open or closed valve can prevent proper air flow into the exhaust. - Vacuum Leaks:
A vacuum leak in the system may disrupt its operation. - Blocked or Leaking Air Hoses:
Cracked, blocked, or disconnected hoses can prevent the system from functioning properly. - Failed Pressure Sensor:
The sensor may fail to detect pressure changes in the air injection system. - Faulty Relay or Fuse:
The air pump relay or fuse could be defective, preventing the pump from working. - Carbon Buildup:
Deposits in the secondary air system passages can restrict airflow.
Risk Level of P1415 Error Code:
A high-risk level means the issue can significantly impact engine performance, emissions, and fuel efficiency, potentially causing damage to components like the catalytic converter.
It is strongly advised to get the car diagnosed and repaired if the P1415 code continues in order to prevent dangerous driving situations.

FAQ’s
What is the P1415 Error Code?
P1415 is a diagnostic trouble code (DTC) related to the Secondary Air Injection (AIR) system. It indicates that the system is not functioning properly on Bank 1, affecting emissions control.
What Causes the P1415 Error Code?
Common causes include a faulty air pump, clogged or leaking air injection hoses, a malfunctioning check valve, or electrical issues in the AIR system circuit.
What is the Risk Level of the P1415 Code?
The risk level is high because a failing secondary air injection system can lead to increased emissions, poor engine performance, and failed emissions tests. Prompt diagnosis and repair are necessary.
Which Vehicles Are Affected by P1415?
This error code is commonly found in General Motors (GM) vehicles, including Chevrolet, GMC, Pontiac, Ford ,Mercedes, BMW and Volkswagen models with a secondary air injection system.
