check my v-tec silenoid and cleaned it up. pulled my oil pan and clean the oil pick up.change the oil and put syntetic oil. check the wiring it has power. check all this stuff already still cant figure whts wrong. vtec dnt kick in i have a h22a on my car. it runs strong no problems besides my vtec. help fellow tuners. wht could be the cause

 

Did it recently stop working or is this a swap that you can get VTEC to work?

 

does it rev past 6500?

 

check the ecu connections then grab a multimeter and check for an open in the wire. i was getting some resistance with my wires but there was an open. and make sure you put it in the right pin on ecu.
