P1613 Lexus Code - Secondary Air Injection Driver Malfunction

Quick Answer

For a short time after the cold engine starts, the Engine Control Module (ECM) transmits command signals to the Air Injection Control Driver (AID) to drive the air pump and the Air Switching Valve (ASV). Common causes include Faulty Air Injection Control Driver (AID), Air Injection Control Driver harness is open or shorted, Air Injection Control Driver circuit poor electrical connection. 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 P1613 Lexus Description

For a short time after the cold engine starts, the Engine Control Module (ECM) transmits command signals to the Air Injection Control Driver (AID) to drive the air pump and the Air Switching Valve (ASV). The AID detects open and short circuits according to the voltages at the AID terminals to the air pump and ASV, and the circuit voltage of the AID power source, and transmits diagnostic information as a signal to the ECM. If the Secondary Air Injection (AIR) system circuit or the AID itself malfunctions, the AID sends a malfunction signal (duty signal) as diagnostic information to the ECM (when the system is normal, a system normal signal is sent). The ECM sets the Diagnostic Trouble Code (DTC) based on the diagnostic information from the AID.
