Thread: TD5 Engine Issue

Does it do it when using the cruise control?
If not, my guess is Throttle position sensor.

I cannot recall if it does it in cruise control....I will go and check now. cheers

Check your battery terminals.

Throttle position sensor it is! Well done and many thanks. I took the beast for a spin up the freeway and sure enough it started to carry on like it did earlier today until I flicked it into cruise control and voila...all good...(did this a few times and also accelerated from 40 Km/Hr in cruise control to 100 km/hr with no hiccups). Next question - do you need a degree in engineering and a super computer to change out the throttle position sensor or does it come as a pre calibrated and zeroed unit which is easily changed out? My guess is the latter but the cynic in me tells me that it is probably hard to get at though! (I have access to the manuals)

Thanks again for your advice, great stuff - I guess the 1900 rpm idle speed should have drawn me to the same conclusion, but you alway tend to think of the worst case defect first.

my understanding is there is a 2 track and a 3 track TPS, if you replace it with the same as what is in there, it just works, if you need to put the other type in, it's a case of using a nanocom or some other similar device to tell the car what type is being installed.
They are a terribly over-priced unit, I once tried to contact the manufacturer direct and they were something like $17 each if you buy 1000 of them, but I believe they cost around the $200-300 mark

Cheers,

Before replacing it,make sure there isnt a foot mat getting jammed in it.
Check your ECU for oil contamination,"Oil in the Harness" is a cause of the pedal playing up.
Is it recording "driver demand error" as a fault???
