TPS reading 10v at wot?? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Doluck · 12-15-2007, 05:45 PM

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?

MURPHY · 12-15-2007, 06:02 PM

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

kuppler8 · 12-15-2007, 06:03 PM

is he having any drivabilty issues?

Doluck · 12-15-2007, 06:08 PM

nope..........

RPS13nutt · 12-15-2007, 06:26 PM

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.

undesiredshoe · 12-15-2007, 11:36 PM

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

cotbu · 12-15-2007, 11:44 PM

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

Gnnr · 12-16-2007, 01:54 AM

Have you checked it with another meter?

GSXRJJordan · 12-16-2007, 02:19 AM

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 ~

RPS13nutt · 12-20-2007, 10:55 PM

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

GSXRJJordan · 12-21-2007, 05:07 AM

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
