Hi lads, Tried to search but couldnt find anything relating to my issue,
I have an ej2 coupe with a b16 swap, im getting a cel code 3 flashing up, I have looked over the wiring going to the map sensor,the wires that are going to my map sensor are pink/wht, yellow/green and green/blue, its an obd1 ecu, the wries are cut and joined over at the passenger side in a big harness and 3 seperate wires run to the map sensor, bit of a botch job, but are these the correct wires? and why the bloody hell cant i make the cel go away?
Thanks for the help!
