DETECTING CONDITION
(DTC will set when detecting:)
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
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
Radiator cooling fan relay terminal voltage is
low when cooling temp. is lower than
specification
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
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 inputed from engine
cranking till its start and after or it is always
inputted
No backup power after starting engine
No signal or check sum error while engine
running
No "D" range (park/neutral position signal) is
inputted while vehicle running
