My buddy has an 01 IS300 that keeps throwing P0125 insufficient coolant temp in a quick enough time. Put a new thermostat in it and bled the system. New sensor too. What else can be done?

He gave me the wrong description of the code. It was for an O2 sensor. B2S1. Wasn't going into closed loop quick enough. All good now.
