Ok well seems
51 is

Diagnosis

No "IDL" signal, "NSW" signal or "A/C" signal to ECU, during diagnosis check.

Trouble Area

A/C switch circuit
A/C switch
A/C amplifier
Throttle position sensor circuit
Throttle position sensor
ECU

I think i am throwing this code becuase my temperature sensor for my AC that is on thermostat housing is the wrong part, so i leave it unplugd, if i plug it in i get no A/C so going to fix this today and reconnect the wire.

I wonder if this has anything to do with my heater core vsv not allowing coolant to flow through my heater core.... some one help
