Great Video! , His job is a professional job , because when he test he show completely + drawing diagram too , and his video without interruptions , no music interruptions , and he zoom in , zoom out for enlarge the picture too , everything is complete , when I saw his video I really appreciate , ❤
thanks for watching..the 4th pin is an IAT (intake air temperature), the car has two MAP sensor, the IAT of the first MAP sensor was used. But the second Map sensor the IAT was not in use, which is shown in the video..The IAT is a varying resistance (which correspond to the air temp) signal to the ECU, and is not 5 volt..
👍👍 do really have removed it from the car, why not just connect your pressure tool and back probe , this way you don't need external power, just a thought.
