Suzuki RA410, Manual

Page: 420 / 761

INSPECTION
1) Disconnect negative cable at battery and connector from TP
sensor.
2) Using tester, check resistance between terminals under each
condition given in table below.
“A”
“B”
“C”
“A”
“B”
“C”
NOTE:
There should be more than 3.5 k
resistance difference be-
tween when throttle valve is at idle position and when it is
fully open.
If check result is not satisfactory, adjust installation angle of TP
sensor and if found defective in the other check, replace TP
sensor (1).
ECT SENSOR
REMOVAL
1) Disconnect negative cable at battery.
2) Drain cooling system, referring to SECTION 6B.
3) Disconnect connector from ECT sensor.
4) Remove ECT sensor (1) from water outlet pipe (2).
INSPECTION
Immerse temperature sensing part of ECT sensor in water and
measure resistance between sensor terminals while heating water
gradually.
If measured resistance doesn’t show such characteristic as shown
in the figure, replace ECT sensor.
INSTALLATION
Reverse removal procedure noting the following.
Clean mating surfaces of sensor and water outlet pipe.
Tighten ECT sensor to specified torque.
Tightening Torque for ECT sensor
15 N·m (1.5 kg-m, 11.0 lb-ft)
Connect connector to sensor securely.
Refill cooling system, referring to SECTION 6B.
ENGINE AND EMISSION CONTROL SYSTEM 6E1-55
