THROTTLE POSITION SENSOR OUTPUT VOLTAGE

1993 Pontiac Sunbird • 4 cylinder FWD Manual • 248,000 miles

I checked my tps as per instructions in my chilton manual and at idle position it reads 5 volts and decreases to.47 volts as I open the throttle to full my chilton manual says it should be just the opposite so is the manual wrong or is the tps bad

Good Luck and let us know what really happened here and also never use anything other than a OEM Parts-We walk a mile long with you and I don't smoke Camel and we still cannot find that water hole-let us know-I thought I know the TPS in and out-I guess its time to refresh on engine electronic computing system as far as parameters and actuators and what exactly the computer is seeing and doing-Good Luck again and Happy Holidays
