Hello,I am Scott and I will assist you with your vehicle concern.
As you can see, after downloading the attached link, to diagnose this system a DVOM and a scanner will be needed. The TPS is an integral part of the ETS system and has other inputs as well.
I also attached the link to Microsoft so you can download the Word 2007 reader in case you do not have it.
Link for repair.
