Ive probbaly asked this before but still have not found out the answer....

Any clue which ECU pin reads the MAP sensor data?

A pin-out diagram for the entire ECU would be nice, or at least + - K-Line etc.

so is the pressure sensor the MAP sensor? red/grey, location 3-10?

or is that the oil pressure sensor?

Thanks for the help !

yes. it shares the ground and power with another sensor.
component 3/10 is the ECU

Hope this helps

thanks guys so red-grey (socket3-location10) is 0-5v output and pink-black 5v input (which also powers the oil sensors) and brown-grey -ve ground?

Just to clarify!

Thx again guys!

On most Euro cars Brown color is the Earth / Ground. I tried to post a color schematic. The colors fade when enlarged

stevebez

but the above is correct?

Do you have a voltage meter Steve? Be good to confirm it with that.

true but how are you going to produce boost so the sensor sends a signal. unless you have a boost leak checker but that will confuse to ecu if it see boost at idle or when the ignition is in position 2

stevebez

yeap got a meter but trying to hook it up is not easy esp when trying to get a boost reading!!.. at mom I am tapping off the red-grey and see how it goes... its for my water injection think I may go boost based flow instead of IDC based flow.

thanks shardul and PTE!

for those interested...

IDC is socket 3, pin 27, grey-black
MAP is socket 3, pin 10, red-grey
+ve injector side, socket 5, pin 9, red-blue

thanks shardul and PTE!
