Lexus is300 Limp mode

Recommended Posts

so recently my wife overheated her is300 (bad radiator cap) and the car went into limp mode. i had to change all of the front seals on the motor anyways so i did that and put a new radiator cap on it, along with a new bank 2 sensor 1 o2 sensor, timing belt and vapor sensor as it was broke. None of this stuff has fixed the problem and the car is throwing no codes sadly any ideas?

If it's not throwing a code I don't think it's in limp mode.  Start checking the basics

do you have any pending codes?  the IS300 ECU is insanely sensitive to things.
