Question about 2002 Ford Explorer
I recently took the engine out replaced a piston and rings. the car crank up run for a second then shutdown itake the plugs out after a day it do's the same again do u know what i'm doing wrong
Hi Ronald, I do not believe the Mass Air Flow Sensor is designed to operate on 12 volts, it usually operates on 5 volts or lower. I suggest looking at the crank and cam pick up sensors and making sure the MAF sensor is not damaged. A digital diagnosis should pin point the problem if it is not mechanical. Regards John

The engine and automatic transmission in this vehicles drive train are fully electronically controlled by a computer called the PCM (Power Train Control Module). Whenever a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM
