Clicking From Throttle Body ?

[true blue]

Hi to every-one hope you had a good new year.I've only had my IS 200 sport cross 2 weeks all OK until yesterday; Stopped for petrol car was just warm -and would not restart,

I eventually tried the old fashioned way,full accelerator and longer bursts on the starter eventually started seemed to run OK after 20 miles engine light came on

Now it runs ok accelerates ok and starts first time hot or cold, I don't have a code reader but I have checked most obvious areas.The only thing I can find is with the engine running

there is a clicking from the throttle body area (like a relay type fault ) and you can see and feel the throttle quadrant and cable move if you hold it when it clicks.It appears a signal

is being sent to control the thottle. Can anyone who has experience of this problem point me in the right direction/ any further checks etc .Thanks ;I tend to panic when I see the

engine light Dave

the throttle does normally give a little clicking sound when the keys in but the engines not on.

or is it doing it without the key in?

No. only does it with the engine running -stopped with ign on-nothing If this is just my inexperience and I have to get a code reader which one is most used on here ?

Thanks for prompt reply

theres two ways really, one that plugs into your computer or a standalone one.

as long a its obdii it should be fine and theres a post here: http://www.lexusownersclub.co.uk/forum/ind...showtopic=52302

about what they all mean.

personally id recommend a standalone one that just gives you the codes and resets them.

I thought clicking at idle was normal? It's modifying the throttle like an idle control valve.

clicking ang humming is normal from the throttle body as it has a servo motor.

Thanks for the info lads , looks like i'll have to get a code reader and find the error code, as the famous man said

I'll be back !!

as rob has said, your supposed to hear a ticking from the throttle, it is mechanically-electronic controlled

so there wont be an error code, there is no error with the throttle
