Need some advice. I have an 01 4runner almost at 200k. I have this CEL for p1760- linear solenoid for line pressure control circuit malfunction. Seems as though this CEL only comes on if it’s over 75° outside. The CEL was not on at all during the winter/cold months when the temps were below 70°. Even, if the temp outside in the morning is below 70° it’s not on, but if the temp in the afternoon is above 75° it is on. I’m really stumped at what this could be. I’m thinking maybe an ECM issue? I have to get it inspected and they won’t pass it with a CEL on.

I had a shop replace (i think) only 1 shift solenoid maybe 20k miles ago for a different CEL.
