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
emission but not to cause damage to three
way catalyst
Knock sensor circuit low input
Knock sensor circuit high input
No signal for 2 sec. during engine cranking
No signal during engine running
Excessive or insufficient EGR flow
EGR valve electrical circuit open or short
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
specification.)
Purge control valve circuit is open or shorted
to ground.
Fuel level sensor circuit open (high voltage)
No signal while running in "D" range or during
fuel cut at decelerating
No closed signal to IAC valve is detected.
Data write error (or check sum error) when
written into ECM
Manifold absolute pressure sensor output
voltage is higher or lower than specified
value (or sensor circuit shorted to ground or
open).
Barometric pressure is lower or higher than
specification. (or sensor malfunction)
Difference between manifold absolute
pressure (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
