chickeneatman Posted February 1, 2021 Report Share Posted February 1, 2021 My Inlet Bank 1 +2 weren't tracking the target so I adjusted the tune to give 5 degrees advance w/o load. Here is the log file. My solenoids do appear to be wired correctly after the 15 times I have checked. Any thoughts?

Vaughan Posted February 1, 2021 Report Share Posted February 1, 2021 Looking through that it appears to be trying to drive the solenoids and so should be affecting the angles. Have you done the cam angle calibration numbers? (using Cam Angle Test -> Calibrate) Have you wired the solenoids up with an Aux out and a switched 12V?

chickeneatman Posted February 1, 2021 Author Report Share Posted February 1, 2021 The 12v is switch on with Ignition. I am using Aux 1-4 for the 4 solenoids. I haven't done cam angle calibration.... Ill start there. Quote Link to comment Share on other sites More sharing options...
Vaughan Posted February 1, 2021 Report Share Posted February 1, 2021 If you set one of the auxiliaries to Test ON (PWM) does the appropriate solenoid make a noise? Quote Link to comment Share on other sites More sharing options...
chickeneatman Posted February 1, 2021 Author Report Share Posted February 1, 2021 I should have thought of that.... Just tested this. No it doesn't. Even stranger, when I enable PWM on Aux 1 (Inlet 1) The other 3 show faults. Turn it off, and fault goes away. Same with other ouputs. Enable PWM Aux 2 (Ex 1) The other 3 fault. It seems something might be wrong with the wiring after all... Quote Link to comment Share on other sites More sharing options...

My +12v is being pulled low on all of the solenoids when I enable one of the 4 aux out. The correct pin is being pulled low with it though.

Vaughan Posted February 1, 2021 Report Share Posted February 1, 2021 That would suggest an issue with your 12V feed, the 12V feed should remain the same voltage at al of the solenoids regardless of what you are doing, it is possible that your 12V feed isn't actually connected and the 12V you are seeing is actually just the weak pullup on the Aux drives. If you unplug all of the solenoids I would expect you to find that the 12V pin is actually floating Quote Link to comment Share on other sites More sharing options...
chickeneatman Posted February 1, 2021 Author Report Share Posted February 1, 2021 This does appear to be the case... somewhere in my harness the +12v got split from the vvt solenoids. Thanks for helping with the diagnosis. Vaughan 1 Quote Link to comment Share on other sites More sharing options...
chickeneatman Posted February 1, 2021 Author Report Share Posted February 1, 2021 That was it. I had cut the 1 2v source near the ECU. VVT is working now! VVT.llgx Vaughan 1 Quote Link to comment Share on other sites More sharing options...
