LS V6 check engine lgt OBD p1413

[aa1872]

I looked up the code and it said "Secondary Air Injection System Monitor circuit Low Voltage" does any one know what I am looking for? maybe you have had the same problem. does any know the location of this monitor/fan.

As a general rule of thumb, it is good to provide both the engine size (which you did in the subject) as well as the vehicle year. However, for this request, the model year does not really matter.

Per the service manual,
"P1413 Secondary Air Injection System Monitor Circuit Low"
"The secondary air injection system monitor circuit is low, indicating the electrical AIR pump is off although the electrical AIR pump was commanded on by the PCM."
"Causes:

• Open B+ circuit
• Open AIR circuit
• Damaged PCM
• Air circuit short to ground
• Damaged AIR pump
• Damaged solid state relay"

"The AIR monitor circuit is held low by the resistance path through the AIR pump when the pump is off. Also, look for open circuit from SSR to AIR pump."

If you'd like a PDF of the troubleshooting section for this powertrain code, send me a private message with an e-mail address and the request.
