DTC Logic

INFOID:0000000012197844

DTC DETECTION LOGIC

To judge malfunctions, this diagnosis measures response time of the A/F signal computed by ECM from the A/

F sensor 1 signal. The time is compensated by engine operating (speed and load), fuel feedback control con-

stant, and the A/F sensor 1 temperature index. Judgment is based on whether the compensated time (the A/F

signal cycling time index) is inordinately long or not.
