ECT SENSOR UNIT INSPECTION
Remove the ECT sensor (page 4-64).
Suspend the ECT sensor [1] in a pan of coolant (50 –
50 mixture) on an electric heating element and measure
the resistance through the sensor as the coolant heats
up.
• Soak the ECT sensor in coolant up to its threads
with at least 40 mm (1.6 in) from the bottom of the
pan to the bottom of the sensor.
• Keep the temperature constant for 3 minutes before
testing. A sudden change of temperature will result
in incorrect readings. Do not let the thermometer or
ECT sensor touch the pan.
Measure the resistance between the ECT sensor
terminals [1].
Replace the ECT sensor if it is out of specification.
ENGINE OIL PRESSURE INDICATOR/
EOP SWITCH
SYSTEM INSPECTION
The engine oil pressure indicator [1] comes on when
the ignition switch is turned ON, then goes off when the
engine starts.
If the engine oil pressure indicator does not come on
with the ignition switch turned ON, check the
combination meter system inspection.
– NC700X/XA/S/SA (page 22-8)
– NC700XD/SD (page 22-9)
The engine oil pressure indicator does not go out when
the engine running, check the following:
– Engine oil level (page 3-12)
– TXD/RXD line (page 22-11)
– MIL blinking: If the MIL blinks 87, check the EOP
switch system (page 4-62)
– Engine oil pressure (page 9-6)
– EOP switch line (page 22-20)
– Replace the EOP switch, and recheck (page 22-20).
If the above items are OK, replace the combination
meter assembly.
– NC700X/XA/XD (page 22-9)
– NC700S/SA/SD (page 22-9)
If the MIL and engine oil pressure indicator are stay on
and tachometer, high coolant temperature indicator and
HISS indicator does not come on, inspect the following;
– DTC with the HDS (page 4-12)
– TXD/RXD line (page 22-11)
