I had a remote start installed on my truck last month and every time i use the remote function my check engine light comes on with p0243 and p0480 codes. Unfortunately I moved from the area before I got it completely resolved (the salesman told me the ECU would learn to compensate for whatever changes occurred in the engine and the CEL would go away). I believed him.


Anyway, i noticed last night when driving home that even on level grade going around 75 mph i was running 12-15 pound of boost. Does this sound right??

*P0243 Wastegate Pressure Control PWM
*P0480 Fan 1 Control Circuit


Could something be wonky with my wastegate?

on yea, the turbo timer doesn't work right on it either, the remote start system has a turbo shut down timer but it only worked in the installers lot. grr...

thanks

Sound to me like the install team tapped into the wrong wires.

 

Blown fuse will also pop those codes-fan & wastegate are on the same circuit
