Fault code table
Fault
Symptom
code No.
No normal signals are
received from the cylinder
identification sensor.
11
No normal signals are
received from the crankshaft
position sensor.
12
No normal signals are
received from the intake air
13
pressure sensor.
Intake air pressure sensor:
hose system malfunction
(clogged or detached hose).
14 Intake air system failure (the
pressure is not supplied to the
intake air pressure sensor in a
stable condition)
No normal signals are
received from the throttle posi-
15 tion sensor.
Signal from throttle position
sensor will not change.
16
No normal signals are
received from the EXUP servo
17
motor circuit.
Signal from EXUP servo motor
position will not change.
18
When turning the main switch
to "ON", the voltage value
shows great difference
20
between the intake air pres-
sure sensor and atmospheric
pressure sensor.
