Ok so I got this camaro on trade got it started but it's in Reduced Engine Power mode I've also just replaced th3 fuel pump idk if that's has any relation but it starts and kinda idles I've swapped the throttle body out with a junkyard one had the same result it's showing codes p1120 and p1220 tp sensor circuit 1&2 I'm not good when it comes to electrical so any help is appreciated

 

look at the connections at the throttle send unit at your feet and check wires.

 

the wires look Ok visually i have unplugged the petal while running and got a code but what am I checking for

 

well the codes are showing bad information from both ends. unplug and hook amp meter and cycle the unit to see if the numbers jump around indicating a bad unit. if go up and down smooth it should be good.

 

have you downloaded factory service manual yet or maybe ordered a paper set for you year. download your year here https://www.mediafire.com/?40mfgeoe4ctti
