Cm2250 boost pressure fault

[Marajin]

Elaborating for those who have never seen this.. Thanks Snailexpress for the photo.



The sensor itself slides down into a hole underneeth. It likes to break, it is plastic. Try to lift it up out of the hole straight.


As seen in the pic above, it is not really possible to clean them once they start to read incorrectly as the pressure part of the sensor is up in the head of it, and it gets packed with soot and dust. It is a capacitive type of sensor.. so liquids of any kind will screw up its readings.. therefore, if someone uses spray cleaners on it, it tends to still read incorrectly after. It simply needs replacing when it gets really dirty.. or every couple years at most.

and the part numbers. It is the same part numbers for the IMAP and exhaust gas pressure sensors for the CM871, the CM2250, and the CM2350.



The one on the bottom is the IMAP (Intake Manifold Air Pressure Temperature Sensor). The one on the top is the Exhaust gas pressure sensor. You should change that one too if it is just as old.
