i got a 97 prelude and i got a p1259 and my vtech wont kick and i check voltage on my pressure switch nd vtech solinoid can some 1 help me please cuz im bugging out i cant go past 6,000 rpm and i swapped the solinoid

 

first of all, (vtech) is a phone.

Second of all, try checking your grounds. Are you getting a check engine light? you must be.. What is it?

There is lots of things it could be :

-bad ground to vtec pressure switch
-coolant temp sensor
-wrong ecu
-oil pressure, which wouldn't throw a code, is the oil full?
-Dents in oil pan, again with oil pressure
-vtec solenoid screen gets dirty

 

yea i have a habbit of writing v tech ne how vtec** yea my solinoid is clean and i swapped it with my friends that is working , i got a p1259 i checked the voltage and grounds and there good , only thing that i do kno is my car stays cold and vtec dont kick in if the cars cold but would that cause it to spit a code?

 

some body help me im buggin out i need some answers i want my vtech workin

 

It will not work unless the car is warmed up to operating temperature. I'm not sure why people try to rag on their cars cold but they do.

I'm not sure what a p1259 is, I guess look it up? I only know of the p13 but that's obd1.

If the car isn't reaching operating temp properly your coolant sensor could be bad, that might not throw a code, and would definitely not allow vtec to work.

Does it work?

 

p 1259 is ground fault on vtech solinoin
open fault on pressure switch
oil blockage
and something else jus dont make sense cuz all that is good think the car being cold woul shoot a code like that

Here's another link, thought it would be helpful...

 

hey listen i went to the mechanice and this was the souloution , 1 wire from the pressure switch wasnt connected to the ecu, which is also the reason to why my rpm guage wasnt working so in conclusion if your rpm guage and your vtec aint working i would check the blue and black wire from the pressure switch to the ecu it prolly aint connected propperly G00D LUCK

And don't through codes till i am hitting vtech real hard . so wtf ?????? it was at good temp , But vtech will still hit at anytime ( ONLY TILL 6500 )??????
