P1130 Toyota -

Question

My check engine light on my 2001 Toyota Tacoma has been coming off and on. I had a friend with one of the diagnosis machines, and he tested it, and came back with the code P1130. Is this the air sensor? What to do now?

Hi there,

This code does mean one of the O2 sensors is bad but it's not specific to which one it is. What you need is a scan tool that can read the live data and determine which one of the sensors is failing and then replace it. In most cases replacing the sensor will solve the issue.
