RX 300 Lexus is not raising above 2

Question

When throttling the engine it will not throttle above 2 in the RPM in Cluster.

Answer 1

Will not go past the 2000 RPM, the vehicle is in a limp mode, What need to be done in the first step is access the code that is set, so this way you would have a direction at what is at fault, and the needed repair.
