Hey guys. I cant find the map sensor on my b16a sirII. I must be blind or confused...

 

supposed to be by the firewall along where the fuel filter is

 

i have a b16aSiR2 in my del sol its on the tb like everyone elses.. unless its a real obd-0 car then its on the firewall on the drivers side

 

ok...its a jdm b16a sirII. Theres no map sensor on the throttle body or on the firewall. I swaped it in a cx hatch. maybe the cx d15 had it on the throttle body so when that was removed so was the map sensor?? I think this is way my vtec isnt working and im thorwing code 3...

 

there should be a hose coming off the TB, remove that map from you cx and connect it to that hose and plug in the map sensor and you will be set. zip tie the map to the firewall. my b16a is the same way and it run perfect

no map sensor. so all i gotta do is get a map sensor from which civic? then plug it in and connect the hose? you talkin about the little brass tube stickin outta my throttle body right?...thats the only tube thats not hooked up to something

 

without the map it shouslnt rev past 4k

 

take the map of your old motor, connect it to the map plug then run a vaccum hose to the brass fitting. then reset your ecu and you should be set

 

well it revs way passed 4k. runs really rich tho. it Pulsates at 1500rpm but after that its fine and it idles fine too.....

 

yea the map is on ur old tb. b16a's had the map on the fire wall thats y u didnt notice it missing just find ur plug and hook it up to that brass nipple on the tb, easy fix and will run much better btw ur old map will work just fine, when u pull it off the old tb u will see the nipple on it as well

 

sweet thanks guys for all the help! i already sold my d15 but i have already located one from a buddy and ill try it 2marrow. You think thats why my vtec isnt workin?

Another question, why is there some people sayin there jdm b16's had a map sensor on the tb and some say they didnt have one. iv had a b16a2 and that map sensor is on the tb? can someone explain which jdm b16's had and didnt have it on the tb? thanks!

 

The 92,93 had it on the firewall. The newer ones had them on the throttlebody.

 

cool, thanks for clearing that up for me Endo-land!!! it was buggin the crap outta me!!

 

the newer b16's like the ones from the si have it on the tb. for the eg b16's its on the firewall. if you have an eg b16 with the map on the tb then the tb may have been swapped and vice versa
