3. ENABLE CONDITIONS
Map 2
Add the following value every 512 milliseconds.
4. GENERAL DRIVING CYCLE
Perform the diagnosis only once at a constant 70 km/h (43 MPH) or higher.
5. DIAGNOSTIC METHOD
After the execution criteria are established, calculate the output fluctuation value of front oxygen (A/F) sensor
(averaged for the right and left) and output fluctuation value of rear oxygen sensor. Calculate the diagnosis
value when the front oxygen (A/F) sensor output fluctuation value is more than specified value. A/F response
properties and diagnosis values are parameters for the judgment value.
Judge as NG when the malfunction criteria below are met. Judge as OK if the criteria below are not met.

cles.

GENERAL DESCRIPTION
If the maximum value – minimum value for the fuel level is less than 2 liters (0.52 US gal, 0.44 Imp gal) every
60 seconds, extend 60 seconds more and make judgment with the maximum and minimum values for the
fuel level in 120 seconds. If a difference does not appear though the time was extended 60 seconds, extend
the time (180, 240, 300 seconds) and continue the judgment. If the maximum value – minimum value for the
fuel level is more than 2 liters (0.52 US gal, 0.44 Imp gal), the diagnosis counter counts up.
