#201 Inspection of relay (normally open 5-pin)
•
Check continuity and operating condition of the relay. Replace
the relay if necessary.
#262 Inspection of
Mitsubishi 6M70
water temperature sensor
• Place the water temperature sensor in a container filled with en-
gine oil.
• Heat the oil to each of the specified temperatures. Stir the oil
well while doing so.
• Measure the resistance between terminals 1 and 2.
• If either measurement is out of specification, replace the sensor.
#263 Inspection of
Mitsubishi 6M70
engine speed sensor
• Measure the resistance between terminals 1 and 2.
• If the measurement is out of specification, replace the sensor.
CAUTION
• The signal may not output if the sensor tightening torque is
insufficient. Check if the sensor is tightened with the cor-
rect tightening torque. (See Gr11.)
#265 Inspection of vehicle speed sensor
•
With the 24 volts DC applied to terminals 1 and 2, slowly turn the
shaft of the vehicle speed sensor.
• Measure the maximum voltage (high pulse voltage) and mini-
mum voltage (low pulse voltage) occurring at each specified pair
of terminals.
• If any measurement is out of specification, replace the sensor.
