Probably the one issue I hate the most to diagnose, reason being the codes that cause that message and also cause the vehicle to go into limp in mode can be set by an intermittent fault that is there for .5 seconds or more, and quite often the problem starts out as a once in a while thing, so try capturing a problem on a meter or scope that may only last a fraction of a second and occurs once in a while. The two most common repairs associated with this problem are repairing broken wires at or just before the throttle body assembly in the harness connector and TPS issues in the assembly which require replacing the Throttle body and performing a relearn in some cases.
