P1614 Lexus Code - Secondary Air Injection System Driver Bank 2
Quick Answer
The P1614 diagnostic trouble code for Lexus vehicles specifically refers to an issue with the Secondary Air Injection System Driver Bank 2. Common causes include Faulty Secondary Air Injection Pump: The pump may fail over time due to wear and tear, resulting in insufficient air injection into the exhaust system, Clogged Air Injection Hoses: Debris or buildup in the air injection hoses can restrict the flow of air, preventing proper operation of the secondary air injection system, Malfunctioning Air Injection Control Valve: The control valve that regulates the flow of air into the exhaust system may be stuck or malfunctioning, causing the system to not operate correctly. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P1614 Lexus Description
The P1614 diagnostic trouble code for Lexus vehicles specifically refers to an issue with the Secondary Air Injection System Driver Bank 2. This system is responsible for injecting fresh air into the exhaust system to help reduce harmful emissions. In a properly functioning system, the secondary air injection pump pushes air into the exhaust stream during cold starts to help heat up the catalytic converter faster, improving emissions performance.
Common Causes of P1614 Lexus
- Faulty Secondary Air Injection Pump: The pump may fail over time due to wear and tear, resulting in insufficient air injection into the exhaust system.
- Clogged Air Injection Hoses: Debris or buildup in the air injection hoses can restrict the flow of air, preventing proper operation of the secondary air injection system.
- Malfunctioning Air Injection Control Valve: The control valve that regulates the flow of air into the exhaust system may be stuck or malfunctioning, causing the system to not operate correctly.
- Electrical Issues: Problems with the wiring, connectors, or other electrical components related to the secondary air injection system can also trigger the P1614 code.
Symptoms of P1614 Lexus
- Check Engine Light: The most common symptom associated with the P1614 code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: The engine may run rough or have difficulty idling smoothly, especially during cold starts.
- Decreased Fuel Efficiency: A malfunctioning secondary air injection system can lead to decreased fuel efficiency as the engine may not be operating at optimal performance.
- Increased Emissions: The vehicle may emit higher levels of harmful emissions, leading to environmental concerns and potential regulatory issues.
How to Fix P1614 Lexus
- Diagnose the Issue: Use a diagnostic scanner to read the code and determine the specific cause of the problem with the Secondary Air Injection System Driver Bank 2.
