Cylinder identification
sensor
No normal signals are received
from the cylinder identification
sensor.
Continues to operate the engine
based on the results of the
cylinder identification that
existed up to that point.
Unable Able
12
Crankshaft position
sensor
No normal signals are received
from the crankshaft position
sensor.
• Stops the engine (by stopping
the injection and ignition). Unable Unable

Intake air pressure
sensor (open or short
circuit) (pipe system)
Intake air pressure sensor-open
or short circuit detected.
Faulty intake air pressure sensor
system.
• Fixes the intake air pressure to
85.0 kpa.
Able Able

Throttle position sensor
(open or short circuit)
(stuck)
Throttle position sensor-open or
short circuit detected.
• Fixes the throttle position
sensor to fully open. Able Able

Intake air pressure
Atmospheric pressure
Defective values are detected
due to the internal malfunction.
• Fixes the intake air pressure
and atmospheric pressure to
85.0 kpa.
Able Able
21
Coolant temperature
sensor
Coolant temperature sensoropen
or short circuit detected.
• Fixes the coolant temperature
to 60°C. After the engine
starts, the radiator fan relay will
be turned ON.
Able Able
22
Intake temperature
sensor
Intake temperature sensor-open
or short circuit detected.
• Fixes the intake temperature to
0°C.

Atmospheric pressure
sensor (open or short
circuit)
Atmospheric pressure sensoropen
or short circuit detected.
• Fixes the atmospheric
pressure to 85.0 kpa. Able Able

Oil pressure dropped Engine stops when the oil
pressure drop is detected.
• Fuel pump and fuel injection
are stopped. (Main relay is off.)
Unable Unable

Faulty ignition Open circuit detected in the
primary lead of the ignition coil.
• Cut the injection of other
cylinder in the same group with
the cylinder that the error is
detected.
(Example: when the #1
cylinder is detective, cut the
injection of #1 and #4
cylinders, when the #2 cylinder
is detective, cut the injection of
#2 and #3 cylinders).
Turn on the power to the air
induction solenoid to always
cut-off the air.

from the speed sensor; or, an
open or short circuit is detected
in the neutral switch.
• Fixes the gear to the top gear.
Able Able

Fuel system voltage
(monitor voltage)
The ECU is unable to monitor
the battery voltage (an open
circuit in the line to the ECU).
• Fixes the battery voltage to 12 V.
