DTC Detection Logic

To judge malfunctions, the diagnosis checks that the A/F signal computed by ECM from the A/F Sensor 1 signal fluctuates according to fuel feedback control.

  1. The A/F signal computed by ECM from the A/F Sensor 1 signal is constantly in a range other than approx. 2.2 V.
  2. The A/F signal computed by ECM from the A/F Sensor 1 signal is constantly approx. 2.2 V.
