6-1-16 GENERAL INFORMATION AND ENGINE DIAGNOSIS
DTC
NO.
DETECTING ITEM
DETECTING CONDITION
(DTC will set when detecting:)
MIL
P0335
Crankshaft position sensor
circuit malfunction
No signal during engine running 1 driving cycle
P0340
Camshaft position sensor
circuit malfunction
No signal for 2 sec. during engine cranking 1 driving cycle
P0420
Catalyst system efficiency
below threshold
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.)
2 driving cycles
P0443
EVAP Purge control valve
circuit malfunction Purge control valve circuit is open or shorted
to ground
2 driving cycles
P0480
Radiator fan control circuit
malfunction
Radiator cooling fan relay terminal voltage is
low when cooling temp. is lower than
specification
2 driving cycles
P0500
Vehicle speed sensor
malfunction No signal while running in “ D ” range or during
fuel cut at decelerating
2 driving cycles
P0505 Idle control system malfunction
Throttle opening change is small as compared
with electrically live time. Throttle valve opening
is not within its target range with CTP switch ON
or drive voltage exists though ECM (PCM) is not
outputting ISC drive command.
1 driving cycle
P0510
Closed throttle position switch
malfunction
Switch does not change from ON to OFF
(or from OFF to ON) even when vehicle speed
reaches over (or below) specification.
2 driving cycle
P1250
Early Fuel Evaporation Heater
Circuit Malfunction
Heater monitor terminal voltage is higher than
specified value when EFE OFF or it is lower
than specified value when EFE ON.
2 driving cycles
P1450
Barometric pressure sensor
circuit malfunction Barometric pressure is lower or higher than
specification. (or sensor malfunction)
1 driving cycle
P1451
Barometric pressure sensor
performance problem
Difference between manifold absolute
pressure (MAP sensor value) and
barometric pressure (barometric pressure
sensor value) is larger than specification
during cranking.
2 driving cycles
P1500
Starter signal circuit
malfunction
Starter signal is not inputted from engine
cranking till its start and after or it is always
inputted
2 driving cycles
P1510
ECM (PCM) backup power
source malfunction
No backup power after starting engine 1 driving cycle
P1620 ECU code not registered
P1621
No ECU code transmitted from
Immobilizer Control Module
Refer to Section 8G.
P1622 Fault in ECM (PCM)
P1623 ECU code not matched
