I have one but why do you need one?

Lots of people guess they have a fault but really it's actually a problem elsewhere.

Uhh.. what? I'll take every single one you have/can get. These are NLA and the cost was more than double that when they were available.

Check Will Tillery for a used one. If I recall correctly, I bought the last new one from one of you guys for my old NAS truck.

TPS...one of the many reasons I'm so glad to run a three hundy now.

You may be able to swap pigtails, but I'd be surprised if it still worked correctly with the different connections...some modification required

I would be surprised if it went bad, except for the wires. These are Hall Effect sensors, I believe, nothing to wear out, since the magnet never contacts the windings.

They do go bad. When mine went bad, the engine would suddenly lose power. Replaced the TPS and the problem went away for good. And yeah, ERR2263.

The sensor itself does not wear, but again the wires do.

Are you sure they are hall? I think I cut one open and it was a potentiometer

What makes you think they are hall effect sensors? I figured they are simple pots.

Okay... I just read the manual and it clearly says they are a potentiometer and that is how you test them.

and as such they can be easily tested and verified for correct operations.

Well dip me in sheepshit. Most all OBDII systems use Hall sensors. Mainly due to wiper bounce on potentiometers wipers. It drive the primitive computers OBD systems use crazy. Even most OBD I systems used them for less computing required to sample the sensor repeatedly to filter out the bounce. Manufacturers readily used off the shelf engineering, just adapting the systems to their specific vehicle, but the block engineering remains similar, why many sensors items cross over between multiple vehicles of divergent makes.
