Air Injection Control Driver 89581-34041: An Essential Component for Toyota's Electronic Fuel Injection System
Understanding the Air Injection Control Driver
The Air Injection Control Driver (AICD), also known as 89581-34041, is a critical electrical component in Toyota's Electronic Fuel Injection (EFI) system. It monitors and controls the secondary air injection system, which helps reduce emissions by injecting fresh air into the exhaust manifold during cold starts and low-load conditions.
Function of the Secondary Air Injection System
The secondary air injection system assists the engine in meeting emission standards by: * Reducing unburned hydrocarbons and carbon monoxide during cold starts * Increasing exhaust gas temperature to improve catalytic converter efficiency * Lowering nitrogen oxide emissions under low-load conditions
Troubleshooting and Repair
If you encounter problems with the secondary air injection system, the Air Injection Control Driver may be a potential cause. Common error codes associated with the AICD include: * P1613: Secondary Air Injection System Driver Circuit Malfunction * P1614: Secondary Air Injection System Driver Circuit Open
Genuine Toyota Part: 89581-34041
When replacing the AICD, it's essential to use a genuine Toyota part, such as 89581-34041. Genuine Toyota parts are designed to meet the exact specifications of your vehicle, ensuring proper fitment and functionality.
Additional Part Numbers
In addition to 89581-34041, other part numbers related to the secondary air injection system include: * 89581-34020: Secondary Air Injection Pump * 89581-71010: Secondary Air Injection Check Valve By maintaining a properly functioning secondary air injection system with a genuine Toyota Air Injection Control Driver, you can optimize your vehicle's emissions performance and ensure a smooth driving experience.
