Hi I’m a new owner of a 84 corvette and its codes currently are 22 and 42.
I was trying to tackle code 22 low tps voltage sensor because I thought it would be a piece of cake. It hasn’t
the ground Is completing a circuit and I am getting 5volts from the ecm signal but my problem is the positive wire is getting no signal from a multi meter nor is it completing circuits.
Where does the tps positive signal wire start at because I’m losing track of where it’s going honestly.
I don't really understand your problem description.
One pin should have 5V is generated by thr ECM and you should also have the same 5V at the MAP sensor
One pin should be ground.
The center pin is the signal back to the ECM, and that should vary from about 0.5 V at closed throttle to about 4.5 V att full open throttle.

84 TPS problems.
