DETECTING CONDITION
(DTC will set when detecting:)
Misfire of such level as to cause damage to
three way catalyst
Misfire of such level as to deteriorate emis-
sion but not to cause damage to three way
catalyst
No signal for 2 sec. During engine cranking
No signal during engine running
Excessive or insufficient EGR flow
Output waveforms of HO2S-1 and HO2S-2
are similar.
(Time from output voltage change of HO2S-1
to that of HO2S-2 is shorter than specifica-
tion.)
Purge control valve circuit is open or shorted
to ground
Radiator cooling fan relay terminal voltage is
low when fan command is not outputted
No signal while running during fuel cut at de-
celerating
No closed signal to IAC valve is detected
Barometric pressure is lower or higher than
specification. (or sensor malfunction)
Difference between manifold absolute pres-
sure (MAP sensor value) and barometric
pressure (barometric pressure sensor value)
is larger than specification during cranking.
Starter signal is not inputted from engine
cranking till its start and after or it is always
inputted
No backup power after starting engine
