ENGINE GENERAL INFORMATION AND DIAGNOSIS (H25 ENGINE) 6-1-3
DETECTING CONDITION
(DTC will set when detecting:)
Response time of HO2S-1 output voltage
between rich and lean is longer than
specification.
Output voltage of HO2S-1 fails to go
above specification (or HO2S-1 circuit
open).
Terminal voltage is lower than
specification at heater OFF or it is higher
at heater ON.
Max. voltage of HO2S-2 is lower than
specification or its min. voltage is higher
than specification.
Terminal voltage is lower than
specification at heater OFF or it is higher
at heater ON (or heater circuit or short).
Short term fuel trim or total fuel trim (short
and long terms added) is larger than
specification for specified time or longer.
(Fuel trim toward rich side is large.)
Short term fuel trim or total fuel trim (short
and long term added) is smaller than
specification for specified time or longer.
(Fuel trim toward lean side is large.)
Short term fuel trim or total fuel trim (short
and long terms added) is larger than
specification for specified time or longer.
(Fuel trim toward rich side is large.)
Short term fuel trim or total fuel trim (short
and long term added) 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 low input
Knock sensor circuit high input
No signal for 2 sec. during engine
cranking
No signal during engine running.
