VTEC Issues

**gerardojdm** · 01-10-2009, 11:42 AM

ok im having issues with my vtec. i wired it but it still didn't pop vtec. i thought that i maybe wired it wrong so i disconnected the soleniod and the check engine light came on, so i know i wired it right. then i changed the soleniod and still no vtec. so i took off the whole pressure thingy and solenoid and cleaned them, and still no vtec. ppl ask me if my 02 sensor and speed sensor are connected or if its working and they are. im using a stock p28 and still no vtec so i switched to a chipped ecu and again no vtec... what the problem...

How's your oil level?

**gerardojdm** · 01-10-2009, 11:55 AM

i let the motor warm enough to pop vtec and the oil level looks now normal

check vtec fluid asap

make sure you have a knock sensor, im having the same issue. i need to get it chipped to eliminate knock sensor and tune it.

He is using a p28 which doesnt look for a knock sensor!

sounds to me either wiring, or temp switch isnt hooked up

**Arm&hammer** · 01-10-2009, 04:34 PM

yeah it might be the temp switch like stated above.
i had the same problem in my car.

cherrios you have an ls motor thats why it dont work......lol

**gerardojdm** · 01-10-2009, 05:00 PM

lol ^^ not. the chipped ecu doesnt pick up knock sensor, 02 sensor and one more i that i forgot, but its a chrome ecu that i bought from mr. kidd. but i do have some kinda plug unplugged below the knock sensor that i dont know what it is.. could that be it??

man i had a similar problem as yours, but i had low oil pressure and it ending up being the head. g/l with this cuz it could be various things as you already know.

damn i doubt its my head though, but thanx but hope it aint it..

**99' LuDe** · 01-11-2009, 02:35 AM

probably oil pressure if it still isnt crossing over when its warm.

**Tree** · 01-11-2009, 04:09 AM

umm i had a bad v-tec soleniod and it did not throw code.. you might want to check it.

**99' LuDe** · 01-11-2009, 11:10 AM

My vtec engine r.pm. goes up and down when i starte it up when cold in the morning .Once the enine warms up the check lights comes on after the engine has been shaking . I need help find out what is wrong with car 95 Gsr. Ob1 system.

**mitch lab** · 01-23-2009, 03:33 PM

oil pump can be the cause

VTEC SOLENOID

watch out folks we got the honda technician of the year here.

you need to check multiple things.. if everything is wired up correctly, i would get an oil pressure gauge that has a fitting to screw in place of your oil pressure sending unit on the back of the block to ensure youre getting proper oilpressure to the sending unit.... and make sure that sensor is plugged up, and plugged up good.

if all that checks out then check the wiring for your ECT sensor, and make sure that sensor is good..
