How to test a Throttle Position Sensor on a dirtbike or car.

[TheMozza76]

How can you tell if the TPS is out of position?

[briansmobile1]

@TheMozza76 There are manufacturer specific tests for that.

wires are colored blue for the +....green for the 0 ....yellow w/red strip for the S...and black for the -

[holidayhouse03]

what if the tps has 4 connections...say like on a '94 dodge colt....on the actual tps above the connectors is painted/marked ( + 0 S - ) without the parenthesis of course...the "S" could be an "8" it's kinda hard to tell since they are somewhat faded

funny you upload this - i think mines dodgy atm - the idle valve i've cleaned - the throttle body is immaculate - no vacuum leaks (i think) - so will try this 2nite! thanks

@grishenko45 You're welcome- good luck. This one wound up being the wrong computer year supplied by the owner.

@briansmobile1 mine seems to be ok, i disconnected the vehicle speed sensor which have problems on fords, the revs don't hang anymore - so i need a new VSS, but it still stalls, so a new idle control valve is needed too!

thanks for tellin me man

[briansmobile1]

Hell ya- no worries

[PaulMac199]

how did you fix this bike?

[briansmobile1]

Put the right year computer in it. The customer swapped out his 04 Zuki for an 07 Kawi without swapping the computer too. The throttle curve, timing, etc were all off.- customer failed to tell me this.

Checking things like that is where an old-fashioned analog meter comes in handy. You can see the smoothness of the change a lot more easily on an analog meter.

[briansmobile1]

Very true
