put in a b16 a few weeks ago, but didnt have a knock sensor, thus a check engine light, however i still went into vtec, my car has been out of service for the passed 3 weeks, i just put a new tranny in yesterday start it up today, and i have no vtec, why is this, ill be hooking it up the the scanner as soon as i have time, but wanted to know ur opinions

ill probably get the "could be anything, dude, find what code ur running", but i thought id ask since im bored

first off, you dont need a scanner to check the CEL codes... and did you let the car warm up a while before you tried to take it up to the VTEC RPM range?

 

check the oil also just to make sure

 

car was fully warmed up, and i know i dont have to hook it up to a scanner, but my buddy has one, and i dont ahve any wire... and oil is new has high enough

 

What year is your car? If its OBD1 i dont think you could hook up a scanner to it, but dont quote me on it.

Anyway your problem more then likely is that your in limp mode. Does the car feel weaker? Im pretty sure because of the knock sensor thats why you dont have VTEC. Hook up the knock sensor and your problem should be gone.

hmm, i dont think knock sensor will put your car into limp mode. i dont remember but i think my buddy's b16 was running w/o it.

and make sure you arent running any other CEL's

 

ok, i have no vtec because i have no speedo, but why dont i have a speedo.... i pulled the VSS out and the teeth are fine, and its plugged in well, please well

 

OBD2 motors need knock sensor or vtec wont work depends if your obd1 or 2 :/

 

ima assuming you had an EG. since youre parting out a Z6. in teh EGs there was bad wiring behind the intake manifold in the harness and sometimes the speedo and odometer go a lil crazy. its hard to find. ive yet to find the problem in mine

 

well i never had any problems, and the harness wasnt touched or anything

 

i had the speedo problem in my 95 coupe w/b16 also. check the ground wire to the speed sensor. just run a new ground and make sure it has good connections and a solid ground. also, cut the wire a little way away from the sensor so that you have some leeway to make mistakes. my wires to my speed sensor plug are now about an inch long.

 

check yuor vtech solenoid

 

A) clean out your clip

mine didn't work for the last 2 weeks since i replaced it and whala, it all of a sudden decided to work NOW!. after

B) i ordered a new VSS clip from the harness to hardwire it in. weird.

C)also check my sig

 

guys, its got nothing to do with the connection, i have taken the vss out and while plugged in, turned the VSS and the speedo moves, this shows that the VSS is fine and work, its not catching inside the tranny

 

there is a screen that traps debree from flowing through solenoid. pull it off and check to see if you need to clean tha screen. also the speed sensor on that tranny might be fucked. good luck.
