Hey guys i got a b16 swap done at the end of august.......and i had gotten a CEL, it was a code 3, so i replaced and inspected all the vacuum lines, redid all of them so there all good. I also just got a map sensor from a 90LS in a junkyard and put that on yesterday and it still is giving me a code 3, so i don't get what the problem is?? The only other thing i can think of that it could be is the ecu itself, or the wiring........can anybody help me??

 

does anybody have any ideas i could try?

 

Did you try pluging the MAP itself stright in into the nipple and making sure that it is connected to the ecu? i know it sounds dumb but thats the only hook ups it needs

 

Have you reset the ECU since you've made the changes? The ECU can store the codes even after you fix the problem and will need reset to clear them.

 

Well I had the battery cable off while i changed the map sensor, and then just connected it when i was done, so doesn't that count as resetting it? and ZAXeg i don't know what u mean, plug it into what nipple?

 

Assuming you have an OBD0 swapped B16, you need to configure your MAP sensor and vacuum lines as described:

 

yup i'd seen that before and had done it just so.......still don't know what the problem is.......guessing its my ecu, gonna call HMO tomorrow if i can get a phone card.
