yesterday car had vtec engaging properly, today i take it down the street and nothing.

i checked the wire going to the solinoid with a multimeter and when the car hit 5500 rpms the wire is showing 14ish volts. so the ecu is recognizing and sending power to the solinoid. i have a jdm solinoid with no pressure sensor so the pinout on the harness is chassis grounded. i pulled the vtec solinoid off and the screen is clear...

anyone ever have a v tec solinoid go bad? when i jump power from the battery to the solinoid i can hear it clicking... im pretty stumped. is there a certain point oil pressure wise where vtec wont engage?

my sunpro gauge was wacky on the dyno and then it just stays below zero. the guage works but the sending unit took a **** so i tried installing my new autometer one tonight and my ****in tunertoys block fitting snapped off in the block... so i wont have an easy out and a new fitting till tomorrow... im starting to get a bit frustrated

 

most likely an oil pressure problem, could even be as simple as being low on oil.

 

Check your oil level. Check the screen on the solenoid

 

screen is clear and the oil is topped off and only has a few dyno pulls on it..

i was thinking oil pressure myself unfortunatly but i wont know until tomorrow...

whats the min pressure required to activate vtec?

 

is your oil light connected? if so is it lightly flickering at idle? that would be a telltale sign of bad oil pressure. whats the setup? is it lsvtec or just gsr or b16 whats up

 

factory manual calls for 50lbs.

 

its a piston and rod ls/vtec with gsr oil pump... i dont have the stock cluster in the car. its all aftermarket guages. water temp oil press boost and wideband.

the sending unit on the oil press guage i had in there took a **** and im going to put my new autometer one in the car tomorrow.

i just hope oil pressure isnt he case... motors been running well and its only got about 400 miles on it. if i have the pressure sensor wire chassis grounded the vtec should engage regardless correct/. as the ecu is always thinking it has enough pressure.

whats the minimum poressure required for vtec to actually engage ? first the injector problem and now tis random crap... small issues but im getting tired of them haha

 

welcome to the world of modification, if your getting tired of it with your small problems then stop now and go back to stock LOLOLOLOL

what kit do you have for the lsvtec?

 

dude this is my 10th turbo honda. i know all about it haha... i have a ge kit.

 

installed my new autometer oil press guage. 90 psi on startup and 45 psi when its warm at idle. gotta be some wiring issue i need to address. is it possible for a passage in the head to get clogged with something? anyone ever seen it
?
