MONITOR DESCRIPTION

This DTC indicates an open or short circuit in the circuit containing the air pump assembly of the secondary air injection system. The air injection control driver performs diagnosis of the air pump assembly, emission control valve set and itself and sends the results of this diagnosis to the ECM as a duty signal. When the ECM receives a signal indicating a malfunction in the air pump assembly, an emission control valve set or the air injection control driver, it immediately illuminates the MIL and stores a DTC.

INSPECTION PROCEDURE

NOTICE:
Inspect the fuses of circuits related to this system before performing the following inspection procedure.
HINT:
  1. By using the GTS to perform the Secondary Air Injection Check operation in the system check, the air-fuel ratio and the pressure in the secondary air injection system passage can be checked while the secondary air injection system is operating. This helps technicians to troubleshoot the system when it malfunctions.
  2. Read freeze frame data using the GTS. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.
