Jackaroo TDI Check Engine Light

Mine was dirty - did not need another one - dealer fixed it for a few dollars

Hows this,my check engine light came on last year on a weekend away. I left it until I got home. I lifted up the bonnet & checked the engine, & it was there!, closed the bonnet & the light had gone off!

Keith, The cleaning does work but it is reccomended that you use a non oily cleaner. Biggus Dickus Smithus sells some that work. Isopropal alchohol is good as it dries & leaves no residue. Try cleaning before you buy a new switch. One question... are you using an oiled foam aircleaner? This particular glitch seems more prevalent with Oiled Foam filtes than with paper... the theroy being that microscopic oil droplets contaminate the switch. $250 seems a good price for this replacement... most people are charged around $700 - $1000 for this the dealer will say he has to replace the whole throttle body in most of the cases if you check it out on this forum. Its a bit of a pain to get to it as its between the throttle body & fire wall. If cleaning dosent work drop me a line as I have a friend who may be able to get a genuine switch at a sensible price and you can replace it yourself.

Keith,
if you can locate the throttle body, aluminium towards the rear of the motor with the large air line from the intercooler going into it you will find on that some black plastic components with the usual plug and socket arrangement. the sensor is in this area. I found it easier to remove the whole throttle body and then wash the internals of it. I had 2 problems with mine and the dealer told me that because I had replaced the paper air filter with the oiled foam one that I'd voided my waranty but the other problem was an overheating one... the check engine light dosent give very specific clues as to why its on...
In itself the cleaning is not difficult but it will takea good half hour to get all the other stuff out of the way so the job can be done, get the body off and clean the whole lot in Iso it won't hurt anything just ensure that all is dry before powering it up again. This worked for me but since going back to paper filter I havent had this problem again.

Onya Jackers.......my light has been on for 12 months and whole thing still running sweetly.....might clean it up and go back to paper filters (I am on the finafilter - that's what did it I'm sure) but do we have to pay Holden prices for the papers ?

Same in my case, 99TDI with light on, holden said it was the TPS, $700+ to fix but leave it and she'll be right for a while.
HOWEVER a mate that works at holden (mechanic) came around the other day when I wasn't home and left a message that there is now a differant part available through holden (presumably just the faulty bit and not the entire tps) on the market for a lot less then the $700 originally quoted, this might be the $250 part someone was reffering to?
