For your TPS:

How To Adjust TPS
"Muscle Mustangs & Fast Fords"
April 1993
A voltage reading must be taken using a digital volt/ohmmeter (DVOM) with the Key On/Engine Off and with the Key On/Engine Running. The TPS is located directly on top of the throttle body and is adjusted by loosening the two phillips mounting screws and swiveling the sensor until the highest reading is found. It may be necessary to elongate the holes with a small file to achieve the desired reading.

The spec range for Key On is from .88 to 1.0 volt; shoot for the .97 to .99 volt. With the engine running, the voltage should be no higher than 1.05 volts.

Incorrect Throttle Position Sensor (TPS) voltage will result in reduced performance. The best way to take a TPS voltage reading is by using two safety pins through the wires coming from the sensor. The positive lead is attached to the green wire, while the negative goes to the black wire. Always ground the meter through the sensor's black wire. This gives a direct, and more accurate ground into the computer.


As for the MAF voltage, it is in your other post. However, I am not sure which pin is which coming off the MAF. Sorry. Ask the guys that were posting about it in your other post. I am sure they would help out with more details.
