My TPS is only reading 0.23 volts at idle and 1.89volts at WOT.

If i adjust the TPS to 0.42 volts idle, at WOT it still only reads 1.93 volts :rolleyes:

Gearbox diag is giving me a code 3 (Tps)

Engine idle fine 800rpm and nice steady pickup when touching gas pedal.

I still believe the TPS is faulty as i cant even get it to read over 2 volts at WOT even after cleaning all the connectors and checking/testing wiring.

Any idea's other than a replacement?

try resetting the tps function by disconnecting the plug for 30 secs with engine running then check again

I have done this twice. No luck! The tps resistances seem to be out as well when comparing to this article http://www.twinturbo.net/net/viewmsg.aspx?forum=technical&msg_id=960871

 

I have 21k from c to d terminals instead of 9 k and 0.3 k to 9.5k from c and e terminals :rolleyes:

anyone close with a good tps you can try

plus i remember reading a article where the gearbox was giving a tps code and it was dodgy wiring and he rewired the gearbox tps wiring and the ecu tps wiring and it sorted it

I dont know anyone who may have a spare!

I was thinking the track inside maybe worn?

Think they're only about £40 to buy new :)

i have a 92 jspec auto TT, it's in bit at the moment sort of but its running fine, it's not going any where so you more than welcome to come and try mine, in new maldon just up the A3.

Ok Thanks for the offer ;) i might just buy a new one :)

Has anyone else tested the Resistance on a Throttle Position Sensor?

Across The White to black wire which should vary from 1k to 9k while rotating inner and Red to black wire which should read 9k ish from TT net?? can anyone confirm this?

I get 22k from Red to black wire's hence i think i am only geting half WOT voltage output.

I need to rule out whether its the TPS or not before i buy a new one!

If some one can Test the Resistances on a good TPS it would help me rule it out ;)

How many people have had less than 2 volts from the TPS connector centre(white wire) I bet most are over 3.6 volts??

Well in case no-one has ever seen the Inside view of a Thottle Position Sensor here are some pics :cool:

I have found that the Potentiometer Main Track was worn causing a High Resistance, causing the voltage output to be over half the required output :rolleyes:

With a little help from (Andyduff) we both managed to work out this fault using our Meters and various tests.

Thanks for your Time and Help Andy :)

It seems that these tracks will wear with Useage and Age and cause low voltage signal output to the Ecu.

Glad you found the problem!!

 

Now get your name down for the island trip!

i have one that is working fine £10

i have one that is working fine £10

:headvswal S**T F**K :headvswal

I did think about sending you a pm :rolleyes: I have pm'd a few people but no replies :rolleyes: so i got one off Andyz now ;)

I may pm you later as i may buy one for a Spare just in case i ever need one!

 

Cheers Though

Glad you found the problem!!

 

Now get your name down for the island trip!

I have not got a TPS yet i am waiting for it to arrive!! It could be anytime now!

Wait was that the Door????

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

No :cry:

Will catch up with you soon though Bud :nana2:

Just out of interest what symptoms did you get appart from the gearbox fault number? Just wondering what prompted you to get to the tps and check it

Jumping out of gear and kickdown working over 130mph (Very Bad):rolleyes:

So i tested the Tps which was out of spec
