ENGINE GENERAL INFORMATION AND DIAGNOSIS (G16/J20 ENGINES) 6-23
DETECTING CONDITION
(DTC will set when detecting :)
Short term fuel trim or total fuel trim (short-
vand long term added) is smaller
thanvspecification for specified time or
longer.
(Fuel trim toward lean side is large.)
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
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 volt-
age)
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)
