Mitsubishi 6M70 - Inspection of MPROP

13-92
#574 Inspection of MPROP
(rail pressure control valve)
• Measure the resistance between terminals 1 and 2. Identify
MPROP1 and 2 by “M/P-1” and “M/P-2” labeled on the harness.
• If the measurement is out of specification, replace the supply
pump.
#582 Inspection of Mitsubishi 6M70 injector magnetic valve
• Measure the resistance between terminals 1 and 2.
• If the measurement is out of specification, replace the injector.
#828 Inspection of fuel injection rate adjustment resistor
• Measure the resistance of the resistor number marked on the
fuel injection rate adjustment resistor.
• If the measurement is out of specification, replace the fuel injec-
tion rate adjustment resistor with one that has the same resistor
number and same specified resistance.
CAUTION
• The fuel injection rate adjustment resistor is matched to the
engine. If you replace it, be sure to replace it with one that
has the same resistor number.
