I'm having massive issures with my map sensor. there are 3 wires... yellow red/green and white brown.
+5v -5v and data....
anyway... ive hooked it according to the pinouts but i cant get the map code to clear.. code 3

It is a 89 crx with a A6 block and a y8 head.

I spliced the harness and this is the only code remaining.... since ive converted to odb1.

I ran 3 NEW wires to the map and now am confused about the pinnouts because the write ups say the hasport manual is wrong.. which do i use?


Pinns 21,19 ,17 on d connector of the obd 1 ecu are the map pinns im using...

-x m d

 

bump cause ive got the same problem
