After i changed the oil with Pennzoil Platinum Full Synthetic Motor Oil, and a regular Fram frim grip oil filter. vtec worked for the next two days. About 200 miles where added and it stop working. The car has 12200 mile on the car .
2nd owner of the car and bought it with 9000 miles on it. Its a 2002 thanks

 

Just some FYI, it's VTEC and not VTECH

Have you checked the oil level since the oil change? If not, I'd suggest you do so to ensure you have enough oil.

 

sorry vtec! yea and level is fine and still clean as hell

 

we need more deatails in order to help you.
couple of questions....


1. did you let the car warm up properly first before you tried to vtec?

2. did you mash on the gas when entering vtec..?because you need to in order for vtec to kick in.

3. have you done any types of modification to your car recently.

 

car was warmed up to full temp.
yes i did mash on gas
no mods at all

 

There's a whole trouble-shooting procedure in the shop manual. If it was oil pressure, I imagine you'd get a CEL. Maybe the solenoid is simply bad. I'd look over the test procedure and see if anything rings a bell.

 

you can test your vtec solenoid to see if it's working. i sent you a pm with a diagram. did you tighten your oil filter back on all the way? vtec usually wont kick in if your oil pressure is not high enough.

 

Do a search for "MAP Wack"
IIRC is is on top of UTH in the stickies.
(thanks to xviper)
That might solve your problem.

Let us know what you find.

 

probably u put too much oil??

 

12200 miles on the car....take it to the dealership!
