ok i bought this car from flordia a few weeks back drive it to indiana. and car is great. i just noticed yesterday the vtec is not "kicking" popping whatever the cool slang term is this week. i pulle dtranny 2 weeks ago and fixed it. But i dont think i unplugged anything from motor other then starter , speedo and shit. i put tranny back in and no vtec?. any ideas?

yes. but it was on before this prob started. but yea anyway i need to check to see what it is. kinda hard to get it to someone to test with no plates on it =\ im gonna try tonight tho.

pull the code yourself... jump the diagnostic termanal with a thin paper clip or wire and then turn your key to the on position... you CEL will flash.. 1 long flash = 10 and a short flash equals 1... for example if it goes 2 long flashes and 2 short.. it a code 22.

ok 2 questions about this. 1 wher are the diag plugs on a b16a? and 2. jump them to what? Ive never used a diag tool so dunno much about this thing.

pass side under the dash.. its a little green plug... it will have 2 wire to it... just connect the two by using a wire or thin paper clip.

check the VTEC solenoid near the distributor...check it for signal. Also, do you have enough oil?

talked to another honda guy. yea he told me to connect them using paper clip ill do tonight. is full on oil. i check it daily. when i bought car the ignitor wire was off so i hooked it up and vtec worked. every so often if i hit 6-7k revs it blows alot of smoke like it is pumping to much oil? i dunno how vtec works exactly, so i dunno if ecu still thinks vtec workin and pumping extra oil?

blowing smoke is prolly your ecu richening your mixture cuz it thinks its in vtec (which increases airflow)... so it sounds like a physical enagement problem instead of an ecu problem... pull the codes and get back to us

ok pulled codes got a 21-vtec solenoid. also pulled the TDC sensor and knock sensor. oh yea vss. but i know they speed sensor isnt hooked up. i maybe when reading the codes i got some mixed up but i know for sure that the vtec solenoid showed up it cycled a few times

hook up you VSS.. fix the solenoid... and knock.. all three wont let vtec engage if there are problems. Im not sure the TDC sensor effects vtec.. but id fix that too, that will prolly effect your timing

the vss is broke never has been working since i bought car. i plan to blow out the solenoid tonight with brake cleaner. and i guess buy new knock and tdc sensor.

i was under the impression that you need the VSS to let vtec engage, otherwise the ecu thinks your not moving and wont engage vtec.

well mine has never been hoked up. the sensor is broken. half is in the trans still to old fluid and the other half hangs. the speedo nor the trip work. never have. but i plan on replacing it. so ill replace that first and see if it fixes it.

fix it all... i believe everything thats wrong is needed for vtec... a vtec engine is a picky bitch.. itll only engage if everything is perfect.

since i been lookin what you think? ebay claims to be good used solenoid for 50$ or new for 150ish? also for a vss used one is ok? or better off new? i honestly dont wanna spend 300 on one

you never really know if it works with ebay... seach the forums here and honda-tech and look for someone parting a civic out.

i put a brand new speed sensor on the car. honda parts. and nothing i still dont have a speedo. im assuming ill need new cluster or something?
Greenblurr93

pull the cluster and check to make sure its all there
