Self-Diagnostic Fault Codes, Symptoms, And Probable Causes - Yamaha XV1700PCRC Service Manual

Self-diagnostic fault codes, symptoms, and probable causes

Diagnostic code indication
Code No. Symptom
No normal signals are received from
the cylinder identification sensor.
11
No normal signals are received from
the crankshaft position sensor.
12
Intake air pressure sensor 1 - open or
short circuit detected.
13
Faulty intake air pressure sensor pipe
system 1; a hose is detached, caus-
ing constant application of the atmo-
spheric pressure to the sensor; or, the
hose is clogged.
14
Or, intake air pressure sensor - open
or short circuit detected.
Or, a stuck throttle position sensor is
detected.
Throttle position sensor - open or
short circuit detected.
15
A stuck throttle position sensor is
detected.
Or,
Faulty intake air pressure sensor pipe
system; a hose is detached, causing
16
constant application of the atmo-
spheric pressure to the sensor; or, the
hose is clogged.
Open circuit in the input line from the
sidestand switch to the ECU is
19
detected when the start switch is
pressed.
When the main switch is turned to
ON, the atmospheric sensor voltage
and intake air pressure sensor volt-
age differ greatly.
20
Intake temperature sensor - open or
short circuit detected.
