Help with CEL 3, map sensor
 

I just finished swapping out my z6 with the jdm d15b7...everything ran fine for a while and then the CEL came on with a code 3...i tried using a sensor off another d15b7 and my z6...but no luck...all vacuum line seem okay and know don't know what else to do...help! https://honda-tech.com/forums/images/smilies/emsad.gif

I am also having map sensor problems mine is toast. on your d15b7 does it go on the intake manifold, or on the firewall? I have a d15 map sensor, from my old engine, ill trade ya for your z6 one. also are you clearing your ecu? under your hood there is a fuse box , pull the 7.5 amp fuse closest to the firewall this will clear your codes

Are you boosted? Boost is the number 1 reason to throw the map sensor off.

Luserkid...Nope no boost...thats how i blew my z6 https://honda-tech.com/forums/images...s/emsmilep.gif

sonicivic...i've tried other d15b7 sensors and still getting the cell and it goes on the manifold

check all vacuums and connect it directly to the nipple on the throttle body. resey ecu after each try

Did you reset your ecu after you swaped the sensor? If not try that with the B7 sensor in it.

Re: (Luserkid)
 

Yeah i did reset the ecu(unplug neg. for like 30 sec...right?) and all vacuum are on tight...i'll double check though...

Re: Help with CEL 3, map sensor (lilobusta)
 

yup all vacuum lines are tight...what else? anyone?

before when i had the map code going off i would reset ecu for 30 seconds, nothing. dont know if it makes a difference but it worked after i unplugged the postive for 15 minutes

i'll have to try that in the morn. https://honda-tech.com/forums/images/smilies/emthup.gif
