This is also a good visual guide and gives background on how the TPS works and setting it for the 1UZ:

^^^^^ Much better description CELSIOR,^^^^^ as long as ya got a multi meter (One of the first tools any young mechanic should buy when just starting out.) Thanks.
I didn't realize he had a video for the TPS, I should have cuz he has one for everything. Kelvin is the man.

I think both of the links we shared make for a pretty comprehensive guide

And yeah, I'm learning a lot from watching Cartune's videos too!

It is obvious he has a wealth of knowledge from working on the UZ engines for years and he enjoys sharing said knowledge.
