4-2.5
Intake pressure sensor
*
Location
* Intake pressure sensor principle:
function
:
induct intake air pressure, ECU judge intake or
compress stroke to decide injection & ignition.
theory
:
different pressure outputs diferent resistance.
* intake pressure sensor measurement:
*
fault phenomenon:
Idle speed will be lower than 1300rpm
idle speed will turn off possible
EMS light is on the long 9 short (intake pressure sensor failure)
