ENGINE GENERAL INFORMATION AND DIAGNOSIS (H25 ENGINE) 6-1-25
DETECTING CONDITION
(DTC will set when detecting : )
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.)
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 deceler-
ating.
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 cir-
cuit shorted to ground or open).
Barometric pressure is lower or
higher than specification (or sensor
malfunction).
Difference between manifold abso-
lute pressure (MAP sensor value)
and barometric pressure (baromet-
ric 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.
