Engine/Transmission (1994 - 1998) Tps

[Mackee]

Hi everyone. I am a newbie and just now learning to navigate in here.



I have a question regarding my TPS. It is reading normal with the truck off and the key in the on position. When I check the TPS with the engine running and in the PARK position, it reads 3. 3 volts (78% full throttle). This effects my overdrive.



Can I (should I) take the TPS apart and clean it to see if it will correct itself or just buy a new one from Cummins (or somewhere else)?



Your help and knowledge is greatly appreciated.

do a search on recalibrating the tps , I think you disconnect the battery for an hour and so forth , do a search

Thanks for the info. I tried to adjust it already, however, looking at these directions I may have not done it correctly. I will check it out tomorrow and decide if I need to purchase a new TPS.



I also feel like I need a new fuel shut-off selenoid. Is there a procedure similar to the TPS I should check for before shucking out the dough.



Thanks again for you help.

What makes you think you need a new fuel solenoid? What year is your truck?

My FSS may not be bad. It has been disconnected for years by the previous owner. I hate having to get out, pop the hood, shut her down.



I just assumed it was bad and decided to ask the advice of TDR just to make sure. Thanks everyone for your help.



DieselMinded, thanks for the link. Looks like I will have a lot to do today.



Just for SAGs, I'll let you know how it turns out.
