Tps (sitting flat...like so):
Code:
/--------\_____
| Pin 1
| Toyota Pin 2
| 89452- Pin 3
| 35030 _____Pin 4
\--------/
Resistance (ohms) Before and After cleaning:
Pin1 to Pin2 : Before = 1.05k ; After = 1k
Pin1 to Pin3 : Before = 347 ; After = 190
Pin1 to Pin4 : Before = 1.76k ; After = 1.78k
Pin2 to Pin3 : Before = 1.3k ; After = 1.16k
Pin2 to Pin4 : Before = 1.7k ; After = 1.66k
Pin3 to Pin4 : Before = 1.96k ; After = 1.9k
Resistance (ohms) Before and After cleaning while held open:
Pin1 to Pin2 : Before = 1.92k ; After = 1.88k
Pin1 to Pin3 : Before = 1.97k ; After = 1.96k
Pin1 to Pin4 : Before = 1.76k ; After = 1.78k
Pin2 to Pin3 : Before = 750 ; After = 680
Pin2 to Pin4 : Before = 200 ; After = 97
Pin3 to Pin4 : Before = 590 ; After = 560
So not a huge difference after cleaning...but enough? All values but one had less resistance and that might have been because I wasn't holding the spring open fully for that one value. Would it work better?
I'll probably never know as I don't plan on installing this TB back in my car. It'll go on the shelf if someday I do need it again.
I'd be interested if someone took a known bad one and cleaned it and tried it.
Also...I was reading on a Taco forum that to reinstall this TPS:

all you have to do is replace the TPS, start the truck, let it warm up to operating temp and turn the sensor until the truck is idling at 750 RPMs tighten the two screws and you are done, simple
