What solenoids? And what 12v test? Having same issue and new to this. Thanks in advance for any help***Update*** so after driving the car for around 100miles no new CEL’s. Took the car down to Voodoo Performance here in Phoenix metro and they also didn’t see anything weird. Said to do the 12v test on the solenoids and see if I could determine one was bad. Sure enough the pins on 3 of 4 moved freely with gravity. The one solenoid was stuck and would only protrude when I attached 12v. When I again applied the voltage it sunk back in and would not leave that position without the 12v…. Thanks to everybody that contributed to the conversation I hope this can in turn help another enthusiast As for the 20A fuse, who knows I have 4-20min sessions on Saturday
