P2009 APV motor control circuit low input
x
Detect any of the following condition:
—
The PCM terminal 2D voltage is not within 3.6 to 4.39 V when the APV motor is operating (open).
—
The PCM terminal 2F voltage is not
within 3.6 to 4.39 V
when the APV motor is operating (closed).
—
The PCM terminal 2D, 2F voltage is 4.39 V or more respectively when the APV motor is not operating.
P2010 APV motor control circuit high input
x
The PCM monitors the APV motor control current when the engine is running. If the driver IC current is more
than 10 A
for
5 s
, the PCM determines that there is an APV motor control circuit malfunction.
P2101 Throttle actuator circuit range/performance
x
Detect any of the following condition:
—
The voltage is not supplied to throttle body even though the drive-by-wire power supply is ON.
—
The voltage is supplied to throttle body even though the drive-by-wire power supply is off.
P2122 APP sensor No.1 circuit low input
x
The PCM monitors the input voltage from the APP sensor No.1 when the engine is running. If the input voltage
is less than 0.3 V , the PCM determines that the APP sensor No.1 circuit input voltage is low.
P2127 APP sensor No.2 circuit low input
x
The PCM monitors the input voltage from the APP sensor No.2 when the engine is running. If the input voltage
is
less than 0.3 V
, the PCM determines that the APP sensor No.2 circuit input voltage is low.
P2138 APP sensor No.1/No.2 voltage correlation problem
x
The PCM compares the input voltage from APP sensor No.1 with the input voltage from APP sensor No.2 when
the engine is running. If the difference is more than the specification, the PCM determines that there is a APP
sensor No.1/No.2 voltage correlation problem.
P2195 A/F sensor signal stuck lean
x
The PCM monitors the A/F sensor output current when the following conditions are met. If the average output
current is more than 1.15 A for 25 s , the PCM determines that the A/F sensor signal remains lean.

P2257 AIR pump relay control circuit low
x
The PCM monitors the AIR pump relay control voltage when the AIR pump is not operating. If the control
voltage is less than the specification, the PCM determines that the AIR pump relay control circuit voltage is low.
P2258 AIR pump relay control circuit high
x
Detect the
1.5 A or more
in the output driver IC over-current detection circuit even though the AIR pump is not
operating.
P2259 AIR solenoid valve control circuit low
x
The PCM monitors the AIR solenoid valve control voltage when the AIR pump is not operating. If the control
voltage is
less than 3.5 V
, the PCM determines that the AIR solenoid valve control circuit voltage is low.
P2260 AIR solenoid valve control circuit high
x
Detect the
3 A or more
in the output driver IC over-current detection circuit even though the AIR pump is
operating.
P2270 HO2S signal stuck lean
x
The PCM monitors the input voltage from the HO2S when the following conditions are met. If the input voltage
is
less than 0.4 V
for
40 s
, the PCM determines that the HO2S signal remains lean.
