Does anybody know what these codes mean and what it will take to fix.Thanks for any info

 

P0380 is "intake air heater relay #1 control circuit"
P0121 is "apps singnal volts do not agree with idle validation signal"

 

380 is intake air heater relay no. 1 control circuit. 121 is tps voltage does not agree with map. 121 is causing the light to come on, could be a bum connection @ map sensor or sensor itself, possibly the edge goofing or??????
Good Luck
