Kawasaki KLV1000 (2004) [233/529] C11 cmp sensor circuit malfunction
4-32 FI SYSTEM
“C11” CMP SENSOR CIRCUIT MALFUNCTION
INSPECTION
DETECTED CONDITION POSSIBLE CAUSE
No CMP sensor signal for 3 seconds at engine
cranking.
Metal particles or foreign material being attached
on the CMP sensor and rotor tip.
CMP sensor circuit open or short.
CMP sensor malfunction.
ECM malfunction.
Remove the CMP sensor.
If the metal particles or foreign material is attached on the
CMP sensor and rotor tip, signal not flow correctly to the
ECM. Clean the CMP sensor and rotor tip with a spray-
type carburetor cleaner and blow dry with compressed
air and also change the engine oil if necessary.
• Lift and support the fuel tank with its prop stay. ( 4-51)
1
Turn the ignition switch OFF.
Check the CMP sensor coupler for loose or poor contacts.
If OK, then measure the CMP sensor peak voltage.
Insert the copper wires to the CMP sensor coupler and
crank the engine a few seconds or start the engine, and
measure the peak voltage.
2
O/W, Y/W or B/W wire open or shorted to ground, or poor
, or connection. ( 4-22)
If wire and connection are OK, intermittent trouble or faulty
ECM.
Recheck each terminal and wire harness for open circuit
and poor connection. ( 4-5)
