Question

Went down the road and at engine temp the wrench light came on and failure safe enginge mode came on wanys to stall .replaced thorttle body and still does the same any idea what this might be im stuck

Answer 1

P0320 Ignition engine speed circuit malfunction

P2106 Throttle actuator control system - forced limited power

The engine over heating ? the overheating condition has to be done first.  P2106 is just a information code only, that the FMEM (Failure mode effect management ) is active, This should be set with other code that would be causing the limp home mode. The charging system should be checked. P0320 if this was set with P2106 , Its to your advantage start and do a MAF sensor cleaning,
