Has anyone encountered this code on their vehicle? I attached a diagnostic tool to my GX and came up with a code P0552. The symptoms I am experiencing are, periodically the car will not start out in first gear. It feels like it’s in second or third gear when moving from a stopped position. When the car is underway after about a few seconds, it will select the appropriate gear.

Another code that came up on the diagnostic tool was, C1201 (Brake Boost Sensor Circuit Range/Performance).

I recently had my brakes serviced about two weeks ago and this issue with the transmission started right after the brake service. Could it be the brake sensor?

This is all I am seeing in FSM for P0552




C1201






I see you had this C1201 a number of years back
