VVT light always on !!!

[guile_mrd]

I installed the VVT light as per the instructions from the forum, the VVT light stays on when i start the car, i tried to unplug the OCV to test, with the OCV unplugged the light is off and it only go on at high acceleration, does that mean that the OCV is not working ? I connected the OCV directly to the battery and i heard its clicking sound which means it's working ....

Thanks for your help,

I tried to disconnect and OCV and start the car without it, the engine worked fine and accelerated without any problems! does that mean that the OCV is defective? or is the VVT disabled ?

Salam,

how do you connect the vvt light ?
what ECU are you using ?

Salam :)

I'm using the stock blacktop ECU (89661-1A860), i connected the LED light +ve to a switched 12V power source and the -ve to a 1k Ohm resistor which is connected to the VVT output on the ECU.

 

[chinozie]

the +12V did you connect it to the lower row or upper row ?

 

[guile_mrd]

I used one of the +12V cables near the car key switch, do i have to connect it directly to the ECU +B upper row line?

:hmmmm:

tap it from ECU...B+...lower row...most lower right wire...black-red / black wire...

I connected it to the +B from the ECU and it didn't make any difference .. the light works only if the OCV cable is unplugged, so the next thing i did was checking the 2 wires that connect the OCV, those 2 wire should be +12V when the engine is started and the Red one should become ground when VVT is activated, the VVT Red wire works fine +12V at the start and become ground when VVT activate, the black wire is the problem ... it doesn't give any voltage at all, so as a temporary solution i connected a +12V directly to the black wire after cutting it, everything works perfectly now :) my only concern is that i don't know the source of this black wire and it might be connected to other parts/sensors on the engine that need +12V to work properly, do anyone know the source of this black wire? is it connected to the ECU too?

Do a simple test. Drive your car and rev all the way to redline. VVT function on a 20V is to switch off on full throttle (WOT). So if the light switches off at hard rev then nothing to worry about. Just my 2 cents
