please help with throttle sensor

[speedfreak440]

Hi everyone, my dad has a 92 d250 with a turbo diesel and automatic transmission. The throttle position sensor on this thing goes out about every 3 years. when the sensor goes out the truck starts to pop in and out of overdrive at freeway speeds and eventually wont go into overdrive at all. my question is this-is there any fix or any way to bypass this switch without messing anything up? thank you very much for any help you can provide, my dad is really sick of buying $0.30 worth of material for $260.00 a pop if you know what I mean.

I am noy familar with the 92's but the newer trucks they say to clean them first.
This is using electronics cleaner not brake cleaner.
Spray the TPS real good and work it full range while spraying.
Be real carefull if you wash the motor .

hey thanks for the input, but its not dirty. the posts that are in this little plastic box are metal and they connect to a piece of paper with a circuit bord kinda thing on it. the vibration from the diesel engine causes the posts to break the paper thing up.

Where are you buying them. Try Cummins over the Dodge dealer. I thought the 1st Generation TPS's were cheaper than the 2nd Gen's and the last one I bought was around $130.

hello, I have a 93 cummins ram dodge 1 ton. my tps went out and did the same thing. the people at dodge dealer told me; the tps sits on top of the injector pump and vibrates it's brains out. they know this, but not much can be done. I was told if it happens again, unplug wires, put a looper wire in end of harness. this will
prevent it from up and down shifting, which will hurt the transmission. this will get you home. hope this helps.
