Whats up guys...I was just wondering why v-tec ain't poppin' on my lude...?? The check engine light is on and i checked it already and it's throwing out the tps and ignition coil....is that why v-tec ain't turning on...??? Thanks...

 

Check your oil level and your VTEC solenoid first.

 

yeah i just did an oil change 3 days ago..., but the solenoid i haven't yet...how can you tell if it's the solenoid..??

 

i dont think vtec engages when the CEL is on.

keep poppin and vtec in separate sentences

 

Usually it's these 2 things when VTEC isn't engaging properly. Do a search, too, since this question has been brought up many times.

 

i did, but didn't get any results back...

You have to click on the "Archived" option when you search.

 

yeah..thats what i did, but nothing...but hopefully i'll find it....

 

Vtec wont engage w/ CEL on anyways, good luck fixing it

 

DP said it right.

your car is in limp mode to keep you from doing something stupid

Check your Vtec Selonoid connections (Green plug near distro)

Then check what your CEL code tells you to....I dont know how straight forward this can be

if not, smash your head onto your desk until something useful comes out

 

your tps is probably just out of adjustment...you can adjust it with a multimeter and some patience, or you can go to a junkyard and get a throttle body with tps already set.

 

theres ALOT of misinformation in this thread.

Vtec will engage with the CEL on, just depends on which CEL it is.

you are not in limp mode. REAL limp mode is pretty rare. Its when the car will not rev above 3000 rpms and you have a solid CEL.

I never knew there was an ignition coil cel...?? without an operating coil, the engine would never start since it is what supplies the spark.

and where did you get that these two cel's are usually the causes to vtec not engaging? i think you need to practive what you preach and do some searching/research on your own.

If you have access to a multiemter, you can test your TPS sensor. put the black end of the multimeter to the chassis or some ground and put the red end into the signal pin on the harness. It should read ~45volts closed and approximately 5 volts at WOT.

Go to autozone and have them check the codes because i dunno where you got ignition coil from.

I was still partially right

 

You didn't read what i said B. Rabbit...thats the reason i posted this up cause i don't know why v-tec aint working..I never said because of those 2 problems i have...I just said what codes it was throwing and then i said if this is why...????

 

about the ignition coil..I just said that cause my friend checked the codes and he told me that it was throwing the ignition coil...so i don't know...oh you know what i think he said it was code 15 ignition output signal...what is that..???

i know this. I wasnt directing everything i said toward you.

go to autozone and have them run the scanner on it.

 

so what is code 15 ignition output signal..???

go there and download a helms manual.

 

I thought when you could not engage Vtec and the car would normally rev up to the engagement point was considered limp mode.......hrm

 

limp mode is a solid CEL. the ecu is supplied with a baseline fuel map that IIRC just dumps a shitload of fuel (likely retards timing) and drops the rev limiter to 3k. You can't even drive the car in limp mode. Trust me....i have tried, lol...theres just no power.

here's an example of limp mode.

you have a chipped OBDI ecu. You take the chip out and start the car. That is an example of true limp mode.

 

my cel is on and i still have vtec

Here is simply the best write up on Vtec problems you will find, and guess what ? It's in the FAQ near the top
