Signs Of A Faulty Tps? (throttle Position Sensor)

[lows_13]

If the TPS (Throttle Position Sensor) is faulty, what problems will it cause?

What signs do i need to look for?

it can either lean out of richen the fuel mixture. don't know what to look for though. you can test it with a multimeter, but don't know what output is supposed to be.

In general, a faulty TPS will cause your car to buck and hesistate. It'll feel like a slight misfire. If you have an automatic trans, it will not shift correctly. You can check TPS voltages by following the diagnostics steps in the FSM.

Is it something thats easy to replace?

[Spook's_Skyline]

what range of volatages is ok?

im checking my tps using the powerfc hc

i found with my tps when it played up the warning light would show

so usually i would get out unplug and replug it in

i found the problem to be the loom being on to tight a turn from the tps and causing bad connections in the plug so i moved the loom slightly tighten the pins in the tps and it hasnt played up since so it might be worth trying that first

Has anyone got a pic of where the TPS is located?

[mad082]

its on the throttle body, on the oposite side the where the throttle cable hooks on.

If i remove (unbolt) the TPS from the throttle body, is there anything that can be cleaned, etc?

[lows_13]

Does anyone know if they can be cleaned?

[igota33]

what is your problem? why do you think you have a problem with your tps?

[GTAHH]

You can adjust it by moving it up and down on the throttle body while it's lightly screwed on. Doing this can help to iron out a few probs including idle probs etc.

And no i'm pretty sure from memory it is solid plastic and can't be opened. Try adjusting it

I might give that a go and see what happens.

how did ya go with it? mine is doing all the things stated above might have a bash myself...

if it dont work, where can i get one new? and how much

you can't just adjust the TPS randomly. there's a specific voltage u have to get at idle for them to work correctly. if u adjust them too far then the computer would never enter the idle map or other end it will never enter WOT map.
