can someone help my b16 engine, my vtec no working.. i have check all my wiring and switch all working fine. wat should i do??

 

did you just get the car? maybe you dont have the right ecu. needs to be a p2t or p30.... could be a few others but those are the only b16 ecu's that i know of. if you have something like a p05 v tec for sure wont work cause its not a v tec ecu. plus v tec only works when the car warms up so maybe some type of temp sensor that might not be working???? just some helpful info

 

what chassis, ecu, etc? speedo working? enough oil? wiring? i believe theres a thread/sticky on here that has all the common issues associated with vtec. an easy way tho to see if the solenoid is even good, would be to hook up a power switch to solenoid. use the single gray clip/plug. when car is off.just touch a wire from the positive terminal to the clip on the solenoid side. it should engage when you touch the wire each time. it'll make a clicking sound. then work from there. like i said, look for the thread/sticky.

 

my ecu is p30 and all sensor and switch working fine. i have try hook up a power switch to vtec solenoid and is working

 

did you check oil like haas said. if it is good then you might have an oil pressure issue if its not sensors or ecu.

 

check ur speed sensor or maybe its dirty take solenoid out it has a little screen on there if its dirty clean it hope that helps

 

i have my oil change so oil is not the problem. i will try out the speed sensor hope it work

thk bro

 

did you check your Vtec fluid? it may be low
...
...
...
its right next to your blinker fluid

 

where to check my vtec fluid and how to check whether it at the full level

 

can someone help mi pls ??

 

@OP: There is no such thing as VTEC fluid nor blinker fluid.

 

well some people consider motor oil as "vtec fluid"
since vtec will NOT work if the oil pressure if low.

 

wt is blinker fluid??

 

This I did know, I just didn't want OP to ask us where his "VTEC resevior" is.

 

 

lol. i know. i just felt like laughing.

do you have any CELs on?
check your oil and your wiring

 

check your oil pressure and make sure you have the right ecu

 

i using P30 ECU and my oil pressure reading is around 2-5 ohm.

i have 1 CEL and it is 20 (ELD) any connection to do with vtec

 

Thats your problem.

 

yup. Vtec will not engage if you have any codes or CELs

 

lol, im bumping this due to the lame title, vtec no working... no working eh? hahaha vtec no working.

 

i actually read the post and i dont think ive ever conidered motor oil to be vtec fluid, im going to say that next time i go to a meet/ show /yell anyone got 5w-30 vtec fluid? im running low!!! maybe a wire got sipped or your ECU is shot?

 

Yeah, let's not do that, okay? We don't need any more traffic/clutter in the forums because some high school kid thought it was funny to bump something with incorrect grammar in the title.

 

so bro wat should i do if my car do not have ELD system??

help pls
