What kind of wiring check did you do? Was this just a visible glance or did you whip out the test light and check for any open circuits or short to grounds?

In addition -

What were actual fault codes? Are they still there after resetting and driving again?

And I asked you for the specific fault code(s). If you want real help, you have to supply needed information...

It isn't any of the sensors. You don't have any codes for any of the sensors, so they are not the problem.

Once again, you have either three bad solenoids or a damaged wiring harness. It could be the internal or external wiring, or corrosion on the pins of a connector.
