Hi all -

I'm new to the forum and have a few questions about my '86 F150.

The emissions light is ALWAYS on. I ran the trouble codes and found it to be Code #63 - TPS input too low.

I removed the TPS from the Carb and I THINK I dropped a small part into the engine / on the driveway - but I have no idea of knowing as I cannot find a schematic of the TPS at all. Anyone have any thoughts? Looks like the Carb Throttle Body (TB) just has a bolt head sticking out. The TPS has a plastic, cylindrical hole with two bits sticking out to rotate the sensor. I think I might be missing a small cylindrical piece that fits between the bottle head on the throttle body and the cylindrical opening on the TPS. Any thoughts would be very appreciated. I don't want to waste my time hunting for a piece that doesn't even exist!

Thanks in advance,
Owen

 

Ouch! Suggest checking another like engine or junk yard. Good luck Buddy.
