What is the input voltage at the TPS?

 

Hmmm. the readings i took where the output voltage. Cause like i said the manual only told me the middle wire was the output. So thats what i tested. And my results where the .33 at idle and 1.97 at wot. It says any above .33 at idle and below 4.95 at wot is fine. ?

 

If the sensor isn't getting a proper 5 volt input signal, output signal is going to be skewed as well. I would be interested to see what the PCM thinks throttle percentage is when you have the pedal on the floor. (need a scanner for that.)

 

I actually have messed with that as well. I beleive it was 13% at idle and 69% wot. Scanner stays in the truck

 

Load was 3% at idle
and igniton advance at idle is 19°

 

Ok, numbers don't look too bad...... I would like to see a higher percentage of WOT.... but, much you can do there. I am REAL curious why the voltage is so low at WOT though. It *should* be greater than 3 volts.......

 

Ill test it again after work with my new sensor on there and see if its reading different. I may have tested the wrong wires. I tested the output signal, not input. I didnt know witch one was witch. Witch wires should i be testing if your looking at the sensor plugged in and hooked up. The middle and left? Middle and right?

 

Do you have the service manual for your truck? You can get the factory manual here. Wiring diagrams will tell you which wire does what.

 

I do. Ill post back with results after i get to it hopefully tonight. Thanks homie! Hahah

 

I figured out i had my meter on the wrong scale. Its at .57 idle and 3.60 wot. I tested and had my 5 volts, and a good ground. So that sensor is working as should. Im probably going to throw a new iac at it as well, see if that dont help. My pcm mustve just learned my new tps cause the truck feels alot more responsive today.. Now when i try to idle it by barely pushing on the pedal the rpms jump to about 1700 now. Anything else i should look at?
