TPS on a 91 Park Avenue

[skeeter1949]

Service engine light on my 91 PA came on over the weekend, My Code scanner says it is a code 22 which is low TPS. Manual says that a dealer has to install this part and adjust it. Is this correct. What is to adjust?

Does your scanner have the ability to display the sensor output voltage?

[skeeter1949]

Yes it does. I just realized that and should have know it, but I have been in Iraq for the past year and have not used it at all. It should tell me where to set the voltage. I believe it should be around .040

.4 volts at idle.
