O2 sensor shortage
While inspecting my wiring harness I found a short between the O2 sensor wires. Not the heater wires. The green 'wire within a wire' going to the CIS-E had pinched together and rubbed off the insulator exposing the two wires to each other. Realizing that this most likely put the unit in limp mode, are there any other problems this may have caused, burning up the sensor itself or the circuit in the CIS-E etc.?
