or, the hose is clogged.
Throttle position sensor-open or
short circuit detected.
15
A stuck throttle position sensor is
16
detected.
EXUP servo motor potention
17
circuit-open or short circuit detected.
EXUP servo motor is stuck.
18
Open circuit in the input line of ECU
No.15 terminal is detected when the
19
start switch is pressed.
When the main switch is turned to ON,
the atmospheric sensor voltage and
intake air pressure sensor voltage
20 differ greatly.
