TD5 throttle pedal??

Hi I have a 2000(ym) Disco TD5 what seems to have some "play" at the pedal, I've been told it has to go to a main dealer to have it reset, does anyone know if this is true or is there a quick fix ?

:doh:BOOOOLLOOOXX!!!!!...nothing more simple, the pedal can have play just if something is broken or loosen.....check it yourself

Thanks for your reply, will this cure the play as in the pedal move's a couple of centimetres before the engine rev's ?

U might have to replace it with a new one if the jiggling around there wont cure it cos in this case u have a faulty sensor. Taking into account that yours is 2000MY u have a two track throttle position sensor, three track sensors were fitted just after 2002..... the only situation when u need a tester is that >> copy from RAVE
NOTE: Three track TP sensors cannot be fitted as replacements on vehicles previously fitted with two track TP sensors. Replacement ECM's are configured for two track TP sensors and can be fitted to all Td5 models. When replacement ECM's are fitted to vehicles using three track TP sensors, TestBook or T4 must be used to configure the ECM for three track TP sensor use.

One of the TP sensor failures effect is >> Delayed throttle response. ...it's up to u now m8

It's been like it since we've had it so used to it now. thanks for the reply.

check if the low range switch is connected or that someone has turned the wires round to make the throttle work in the low range setting rather than the high range

could somebody explain what he means by the above?

In high range the throttle pedal range is distributed through only about 60% of the pedal movement to make motorway driving, long journies etc more comfortable. In low range the entire pedal travel is used to make accelorating more progressive and less responsive. If wired arse backwards you can find that in low range you only need to touch the accelerator pedal and your away.

Thanks for that, I checked my switch to night and it looks like you cant put it on the wrong way, but my ECU still says it in low when it's in high, it was checked with hawk eye! I did read a post that said hawkeye and nanocom don't read this right, does anyone no if this is true?

Intresting this, my auto seems to have a lot of travel before engine rpm's increase, I will have to check the low range scenario, out of curiosity why would this have been done???

Mine reads wrong too. I've heard the same as you about nanocoms mis-reading so I've never bothered switching them over. I have to do some wiring this week anyway so I might swap the wires over in the plug just to test the theory.

It was a mistake made on some of the early TD5's I believe

it'll be interesting to find out what happens, and if it works i'll be doing the same, i wasn't going to bother, and a new switch is £56 so won't be trying that either, did speak to my local indy and they have only ever sold 1 high/low switch in the last 10 years, and the main stealer have never sold one..... if this is another one of those "common" problems you would have though it would have ben reported more

Hi all for any one who's interested I changed my wires around today so that my ECU read high instead of low, when it's in high, it turns out that I get better throttle response when it reads the other way, so I changed it back, I had about 10 to 15 mm before my throttle started to work, it now works straight away again now, does any one know if that's what they do when you have a remap?

if hill decent (HDC) works in hi range than the switch/wiring is wrong and my hi lo switch dont work since i when swimming but can live without hdc and dont bother me using low range

dont see how swoping the wires over will change any thing on is on and off is off no matter how a switch is wired

A potentiometer isn't a switch as such. The position of the hi/low switch dictates the settings for the potentiometer.

The vehicle is mapped to give a less agressive response when in low range. In high range only around 70% of the pedal travel is utilised. In low range the power is spread over the full 100%.

I changed mine today for a used one from the bay. So much nicer to get back the 'loud pedal'. It was no fun driving home from work on tickover...
