k..since i had a new timing belt put in my car last week, my car has been awesome and vtec worked great..kicked in at 5000 in every gear, the whole works.
the vtec was working perfectly all last night as i drove around town with friends...but tonight i drove the car for the first time since last night and after about 5 minutes of driving, i noticed the check engine light was on...but nothing was happenin in the car, it was running fine, no problems...

then i thought of vtec and i tried it and it didnt kick in at all...got to 5000 in 3rd i think and no vtec, just kept going normal...still no problems with the engine in any other way, but just no vtec in any gear...looked under the hood, didnt see anything outta the ordinary (dont really know what i was looking for)..anyone got any suggestions or answers as to why this happened? i have no vtec now, it sucks cause i was just about to try to sell my car and i cant have this problem...also i just had the oil drained and replaced as it got fixed. thanks...this sucks

 

and yes it was cold out tonight, but thats not why its not working since the check engine light is on and i drove enough for the engine to warm up and it still didnt work/light stayed on..****

 

go get a paperclip and search for how to pull codes...you'll need to know what code before anyone can help, good luck

 

whatya mean paperclip?
can someone please tell me how to find out what code its showing please? thanks..im not incredibly knowledgeable in this area

there you go buddy.. step by step info... good luck and hope you fix the problem

 

thanks dude

 

so instead of speaker wire, i can use the two ends of a paperclip and just stick those in the sockets?? what else can i use to stick in there?

and in this thread https://honda-tech.com/zerothread?id=682412
i see that the codes 1-74 are there but what are all the P0.... ones?

yes you can use the 2 ends of a paperclip... i think the P0 codes are obd2 codes if i am not mistaken? not sure.. sorry cant help there

 

What year is your car and what motor are you running, and please state if you are running a conversion harness.

 

1994 civic ex...motor is a 93 gsr (b17a1) block with 99 civic si (b16a2) head...not sure if harness is conversion or not

 

ok..just put the two ends of a paperclip in the two sockets of the plug and turned power on but the check engine light just stayed on..no blinking or anything, i tried a couple of times while adjusting paperclip ends but it didnt work

 

can anyone help on this? i mean the vtec was literally working no more than 20 hours ago, and now all of a sudden theres a check engine light and no vtec..but everything else works fine..nothing has happened since then except that i drove about 30-45 minutes back to school after driving 30-45 minutes from school in the same night...i cant figure this out...also i put the paperclip in the plug outlets to check the code but it didnt blink at all..and im pretty damn sure i did that right...ahhh!

 

check the oil again, make sure it is full. I dont know what else besides that.

 

yep..just got the oil drained because i needed a small hole in the oil pan welded..and he refilled it..and for the past week since i got it back it has been running great, vtec and everything..and now all of a sudden this happens...a check engine light and no vtec...still have full oil level though...god this sucks. i just spent 550 bucks on getting a shitload of stuff fixed like new timing belt, cooling fan fixed, and the oil pan welded, i really dont need to spend hundreds more getting this fixed. my dad is gonna kill me since we finally thought everything was fixed after over a month.

 

 

think i found out my solution....thanks to downey! thanks again ppl

 

bring it to a mechanic or something and ask them to run the codes.. and they'll tell you whats wrong.. or just recent the ECU.. what car and what motor?

 

check your connectors on your TPS and vtec switch and sole.

Congrats, did downey by any chance mention how "checking for vtec" with a CEL on really isn't such a good idea?

*drumrolls* and the problem was......

 

Check your oil level, and your coolant level...

 

sorry here was the problem...i checked what code it was throwing and it was code 21 which is defective or unplugged circuit for the vtec solenoid/defective solenoid. so i looked at the wiring for the solenoid and sure enough the wire going straight up to the bottom of the solenoid was broken...it looked like the bolt holding the bracket for my coolant overflow resovoir rusted off and left the resovoir hangin freely in the engine bay, and that must have caused the wire to break cause the wire is right next to the tank...so i just jammed the broken wire back up into the little outlet hole in the plug going to the solenoid and the check engine light was on no more and the vtec worked great! now i just gotta re-connect the bracket for the overflow tank and make sure the wire permanently stays in that hole! thanks again for the help downey!

 

by the way, this site tells what the codes mean more in-depth
