Mitsubishi Repair Problems? Ask a Mechanic for Answers ASAP
Hi, I'm Chad. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
1- let him check for vacuum leaks ?
2- you can do that by spraying starting fluid around the intake manifold while running but do it ON A COLD ENGINE NOT HOT ?
3- If you changed the sensor and still getting code , i sent you the circuit diagram , the pcm controls the ground to the sensor , he can test there , if ground is missing then either a bad pcm ( computer box ) or the wiring to it , look at the diagram and you can see the flow of the circuit from sensor to pcm
CIRCUIT OPERATION - A 5-volt voltage is applied on the manifold differential pressure sensor power terminal (terminal 3) from the PCM (terminal 46). The ground terminal (terminal 2) is grounded with the PCM (terminal 57). - A voltage proportional to the pressure in the intake manifold plenum is sent from the manifold differential pressure sensor output terminal (terminal 1) to the PCM (terminal 91).
please let me know
