Sounds like the same problem I’m having. As soon as outside temperatures are over 40 degrees the truck throws the codes, is in limb mode and is practically undrivable.
Would you recommend pulling the fuel pump and have it cleaned ?
And tips on how to adjust the pump properly?
Did you ever figure out what the problem was ? Land Cruiser does exactly the same thing.
Had the throttle body cleaned, the crankshaft sensor renewed yet the Check engine light keeps coming up and the car gets undrivable.
I would greatly appreciate your info.
Best regards
