ENGINE GENERAL INFORMATION AND DIAGNOSIS (M13 ENGINE) 6-2-17
DETECTING CONDITION
(DTC will set when detecting:)
Output voltage of HO2S–1 fails to go above specifica-
tion.
(or HO2S–1 circuit open or short)
Maximum output voltage of HO2S–2 is lower than speci-
fication or minimum output voltage of HO2S–2 is higher
than specification.
Total fuel trim is larger than specification for specified
time or longer. (Fuel trim toward rich side is large.)
Total fuel trim is smaller than specification 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 emission but not to
cause damage to three way catalyst.
Knock sensor circuit shorted to ground (low voltage)
Knock sensor circuit open (high voltage)
No signal during engine running
No reference signal during engine cranking or pulse
number of position signal is out of specification.
Insufficient EGR flow
Excessive EGR flow
Output waveforms of HO2S–1 and HO2S–2 are similar.
Monitor signal of EVAP canister purge valve is different
from command signal (circuit open or shorted to ground)
Radiator cooling fan relay terminal voltage is low when
cooling temp. is lower than specification.
No signal during fuel cut for specified time or longer
Voltage is out of specification for longer than specified
time
Data write error or check sum error
Data programming error
Starter signal is not inputted from engine cranking till its
start and after or it is always inputted.
Backup power voltage is out of specification after start-
ing engine.
