Hello,

Having an issue with my TPS adjustments. Holley HP EFI. Brand new AC Delco TPS at idle the sensor is reading +4.5 volts and the voltage decreases at WOT. The voltages are reversed for some reason. Any input would be greatly appreciated.

Thank you
 
Is the TPS new ?? Because the 84-85 TPS is wired opposite of the 86-87 and look the same . Which would do the same thing if the plug is correct for 86-87 TPS and you got a new 84-85 TPS . You can swap wires to fix though .
