D15z8 vtec testing

[Mp3civic]

Hi im new to the forum proud owner of a red MB3 vtec-e from Sweden slmost rust free execpt key hole for the trunk.

 

i was a owner of the same car for a few years back and i remember that there is an econo light that is green for better gas consumption.

 

in my civic now the green light never appeara during drive. Only when i start up the car when all the dash lights light up and goes away.

 

im suspecting my vtec isnt working properly ( no CEL ) i tried to rev the car out and i feel an ” light omph ” with vtec.  But whats bothering me is my gas mileage sucks cuz the green light isnt working properly.

 

i tried ohm testing the vtec. I unplugged the cable used the cable from the solenoid and ground it to body of vtec same as car metal but no readings there. I might do it wrong but i need help to test it properly and what the testing acutally means.

First thing to do is clean the vtec solenoid as it might be bunged up. Easy to remove clean and best to rule that out first.

Wanted to update my scenario, reason why i had no CEL is because the previous owner removed the bulb i inserted a new bulb and got code 7 ( TPS sensor ) i bought a new one and calibrated it and now the vtec-e works. the other factor was that my air intake was ruptured and they had taped it before to hold, now i got a new one from the scrapyard and now the vtec-e works.

 

i asked my local honda dealer and that person said that the vtec-e goes on vaccum and vtec-e solenoid.
