C15" (P0115-H/L) Ect Sensor Circuit Malfunction - Suzuki GSX-R1000 2007 Service Manual

"C15" (P0115-H/L) ECT SENSOR CIRCUIT MALFUNCTION

DETECTED CONDITION
C15 Output voltage is not within the following
range.
0.15 V
P0115 Sensor voltage is higher than specified
H
value.
Sensor voltage is lower than specified
L
value.
ECT sensor
When using the multi-circuit tester, do not strongly touch the terminal of the ECM coupler with
a needle pointed tester probe to prevent the terminal damage or terminal bend.
INSPECTION
Step 1 (When indicating C15:)
1) Turn the ignition switch OFF.
2) Lift and support the fuel tank. ( 5-3)
3) Check the ECT sensor coupler
If OK, then measure the ECT sensor voltage at the wire side
coupler.
4) Disconnect the coupler and turn the ignition switch ON.
5) Measure the voltage between B/Bl wire terminal
ground.
6) If OK, then measure the voltage between B/Bl wire terminal
and B/Br wire terminal
Sensor voltage < 4.85 V
for loose or poor contacts.
.
POSSIBLE CAUSE
• ECT sensor circuit open or short
• ECT sensor malfunction
• ECM malfunction
• ECT sensor circuit open or ground circuit open
• ECT sensor circuit shorted to ground
