Mitsubishi Suzuki MAP Sensor MD355556 Engine Intake Precise Control Replacement

Mitsubishi Pajero and Suzuki Vitara intake pressure sensor (MAP) MD355556, installed on the intake manifold; monitors intake pressure and temperature in real time and transmits signal to the ECU to precisely control fuel injection and ignition timing, directly affecting air-fuel ratio and combustion efficiency. Installation difficulty is low to medium; recommended labor 20-30 minutes; ensure sealing ring is clean. If the vehicle shows rough idle, sluggish acceleration, abnormal fuel consumption, or MIL, sensor signal drift is likely; replacement advised.
