2014 Hyundai Elantra GT, ECM/Inputs/Outputs Waveform 2014 Hyundai Elantra GT, ECM/Inputs/Outputs Waveform I have had VVT solenoids on various vehicles where the solenoid pintle is stuck in the on position and the ecm will have cmp, ckp sync codes. This is a good way to see a bad solenoid without removing it. In some engines, you have to remove the intake to remove the solenoid.

I connect an amp clamp to a ground wire and I ground the VVT solenoid to show the pintle hump.
