noob stumped on map sensor issue
Hi guys,
Newbie from Ireland,
Recently b16'd a 95 coupe, everything went good, cars running good, getting a cel code 3 tho, i have gone over my wiring 10 times to be sure, im using a p30 obd1 ecu, colors i have are pink/white(output),yellow/green(VCC1) and green/blue(SG1), I have a skunk2 inlet and throttle body,keep getting a cel code 3 and cant get rid of it, next option i think would be to run 3 wires from the map to the ecu to make sure there is no wiring issues, anybody care to give me some advice? also would cel 3 cause the vtec not to engage as currently its not working,
Thanks alot in advance!

map is one of your main sensors. if its out of comission, your car goes into limp mode and the pcm uses another strategy wherein the pcm actually looks and depends on the TPS sensor. You must fix the map issue since itll affect other emission control systems that you have such as the egr valve.
