ON-BOARD DIAGNOSTIC [13B-MSP]
01-02–12
P0333 KS No.2 circuit high input
x
The PCM monitors the input voltage from the KS No.2 when the engine is running. If the input voltage is more
than 4.0 V , the PCM determines that the KS No.2 circuit input voltage is high.
P0420 Catalyst system efficiency below threshold
x
The PCM monitors the input voltage from the HO2S and the A/F sensor output current when the following
conditions are met. If the input voltage change is extremely large compared to the output current change, the
PCM determines that the catalyst system has deteriorated.
MONITORING CONDITIONS
—
ECT: more than 70
q
C {158
q
F}
—
Catalyst converter temperature:
more than 400 q C {752 q F}
—
Engine speed: less than 5,000 rpm
—
LOAD:
20–50 %
(maximum calculated load value varies depending on engine speed)
—
Time with purge control system does not operate: more than 20 s
P0441 EVAP system incorrect purge flow
x
The PCM monitors the purge line vacuum, when the following conditions are met. If the vacuum between the
charcoal canister and the intake manifold does not reach the specification, the PCM determines that the EVAP
system purge flow is incorrect.
MONITORING CONDITIONS
—
Vehicle speed: 70.1–130 km/h {43.5–80.8 mph}
—
Engine speed:
1,200–4,000 rpm
—
Throttle valve opening angle: 10.2–27.7 % (changes by engine speed)
P0442 EVAP system leak detected (small leak)
x
The PCM monitors the pump load current (EVAP line pressure) when the specified period has passed after the
EVAP system is sealed when the following conditions are met. If the pump load current does not reach the
reference current value within the specified period, the PCM determines that the EVAP system has small leak.
MONITORING CONDITIONS
—
BARO: more than 72 kPa {542 mmHg, 21.33 inHg}
—
IAT:
5–40
q
C {41–104

—
Fuel tank level: 15–85 %
—
Battery voltage: 11.0–20.0 V
—
Ignition switch: OFF
P0443 Purge solenoid valve circuit problem
x
Detect any of the following condition:
—
The control voltage of the purge solenoid valve is less than specification even though the purge solenoid
valve is off.
—
The current in the output driver IC over-current detection circuit above 3.5 A even though the purge
solenoid valve is ON.
P0455 EVAP system leak detected (large leak)
x
The PCM monitors the pump load current (EVAP line pressure) when the specified period has passed after
EVAP system is sealed when the following conditions are met. If the pump load current does not reach the
reference current value within the specified period, the PCM determines that the EVAP system has a large
leak.
MONITORING CONDITIONS
—
BARO: more than 72 kPa {542 mmHg, 21.33 inHg}
—
IAT:
5–40 q C {41–104 q F}
—
Fuel tank level:
15–85 %
—
Battery voltage: 11.0–20.0 V
—
Ignition switch: OFF
P0456 EVAP system leak detected (very small leak)
x
The PCM monitors the pump load current (EVAP line pressure) when a specified period has passed after EVAP
system is sealed after the ignition switch is turned off. If the pump load current does not reach the reference
load value or the rate of the load increase is lower than specified within a specified period, the PCM determines
that the EVAP system has a very small leak.
MONITORING CONDITIONS

P0480 Cooling fan relay No.1 control circuit problem
x
The PCM monitors the cooling fan relay No.1 control voltage when the PCM turns the cooling fan relay No.1 off.
If the control voltage is low, the PCM determines that the cooling fan No.1 control circuit voltage is low.
x
The PCM monitors the cooling fan relay No.1 control voltage when the PCM turns the cooling fan relay No.1 on.
If the control voltage is high, the PCM determines that the cooling fan No.1 control circuit voltage is high.
