DTC TROUBLESHOOTING
“C12” (P0335) CKP SENSOR CIRCUIT MALFUNCTION
On model K7, the connector terminals to be used for checking
sensors for voltage, resistance or continuity at the ECM terminal
are located as shown in the illustration.
* Refer to the SV650/S service manual 4-23 for details.
“C13” (P1750) or “C17” (P0105) IAP SENSOR CIRCUIT MALFUNCTION
INSPECTION
NOTE:
After repairing the trouble, clear the DTC using SDS tool.
Step 1
(When indicating C13/P1750 for rear cylinder IAP sensor)
(When indicating C17/P0105 for front cylinder IAP sensor)
1) Turn the ignition switch OFF.
2) Lift and support the fuel tank with its prop stay.
(#SV650/SK3 5-6)
3) Check the IAP sensor coupler (Front cylinder side
1 or Rear
cylinder side
2) for loose or poor contacts.
If OK, then measure the IAP sensor input voltage.
ECM coupler (Harness side)
DETECTED CONDITION POSSIBLE CAUSE
IAP sensor voltage low or high
0.1 Sensor voltage 4.8 V
NOTE:
Note that atmospheric pressure varies depending on
weather conditions as well as altitude.
Take that into consideration when inspecting volt-
age.
• Clogged vacuum passage between throttle body
and IAP sensor.
• Air being drawn from vacuum passage between
throttle body and IAP sensor.
• IAP sensor circuit open or shorted to ground.
• IAP sensor malfunction.
• ECM malfunction.
