Hi everyone: '91 Blazer, 4x4, 4.3l, 2dr, standard shift.
I've been reading thru posts here and elsewhere for several days, didn't find an answer. Trouble codes posted: 22 & 34 (tps & map- low voltage. Checked and no 5v vref provided at sensors.

Is it possible to get 5 volts from another sensor....run a wire from it to the tps and map?

Thanks for any help you all can provide. Be happy to detail my car issues if I can't solve it by doing this.

Jazzy
