On a friend of mines car: Its a NA RWD SR20DE

ok i checked (wht) signal and (blk) ground also battery ground
adjusted so that closed throttle is .49
and wot is 10v

Everywhere i check says it should be a little over 4v wot
half throttle i get 5v though.

i dont think its the sensor because it gradually goes up as i turn the potentiometer...(i think i spelled that right )

also not a faulty ground because the battery ground is the same as the tps ground.

could it be wiring?

replace the tps. that reading's 5v's off lol. even if it goes up gradually that's a good start

that's weird tho

there really is no issue normal driving,
as for getting on it, the car pulls easier when i let off the gas a little, lol.
probably because the 5v on half throttle

so i just wanted to check the tps and found 10v wide open
I will borrow another tps to see if it does the same thing

Is he getting power from the ecu or a 12v source.

No way is it possible to get a 10v reading when its only suppose to be supplied 5 volts. Something is fucked up

yes and yes the wiring, I doubt the ecu is fubar check another sensors voltage like mafs

yeah 12v is comming from the ecu

I'll check the maf soon, i was over a friends house when i used the multimeter
I'll buy one and see

Have you checked it with another meter?

lol I'm surprised no one caught that before Gnnr - if the MAF's getting 12V instead of 5V, nothing would be running correctly. It's probably just the multimeter ~

finally got my hands on another multimeter, and it turns out to be the meter was faulty,
thanks for the help on this

Good, thanks for not leaving the thread hanging.

"El Jefe the Wiring Guru" was right again! lol

Ha ha, good thing. I was going to ask if you had set your multimeter correctly
