Can you provide the TIS reference to that, so I can take a look

Keep searching and searching with different parameters on TIS, can't find any reference.  Could really use the bulletin number

[TheBoy]

its on vauxhall germany web site under engine code.

Linky?

[rustym95]

ill try and find it again latter as just done net wipe.

[rustym95]

I cannogive you the link germay, as just found out you have to be a member and have the download on pc, but here is a link to how they work and what they do,http://www.shyauto.com/Downloads/RX0709.pdf

Reasons for failure:
Constant throttle movement wears through the resistive wiper-tracks, the first 30 degrees
of throttle movement is the area in which most wear failures take place. This usually
results in flat spots or holes in acceleration or tick-over problems such as stalling.
Other failures are due to the environment in which the potentiometer is located; it suffers
from dirt, water and vibration damage as well as over-voltage damage due to wiring
faults.
and just one more
Caution:
The idle position of the sensor is critical. There is often a specific voltage setting that
should be checked during any engine management system check. Any wear in the
vehicle’s throttle linkage, mechanism or body will cause a misreading at the ECU, which
will result in a tick-over problem. (this is free information).

None of that is relevant to any modern engine management system, Omega included.

The original link you can't show us, is it from WebTIS? If so, can you just provide the TIS document number so I can look it up?

that is how it works i dont have tis and you know that the boy. this are fitted to every engine with an ECU just read it all.

[TheBoy]

Having read the entire pdf, its sales blurb for their product.

The Omega uses the 'reverse' method of 2 pots, as resistance increaes on one, other reduces.

Wear is not an issue on the Omega (or virtually all other modern injection systems).

There is sufficient range in the sensor on Omegas so the sensor itself would never be the endstop.



Anyway, end result, the butterflies should be 100% closed on the throttle at idle, and it is incredibly rare (ie, unheard of) for these to adjust themselves, so if they are out, someone with ego exceeding talents has buggered around with it

[rustym95]

oh and if you have readit will find out there is no code in ecu. so why would it be in tis.

[TheBoy]

i dont have tis and you know that the boy.

If it is a GM Europe briefing, then it will be via TIS (or WebTIS if online), hence why I was after the TIS doc number

[TheBoy]

its on vauxhall germany web site under engine code.

I'm confused now, its on Vauxhall Germany (presumably you mean Opel) website as a technical document, but not on (web)TIS so dealers will never see it  :-/, or as a public link so nobody will ever see it  :-/



Anyways, entirely irrelevant - any fault on sensor will be flagged by engine management ecu.

[rustym95]

if that the case, i give u the spec's, i dont have tis, and cannot give you the linc to GM as its an account and you have to do it your self as it is locked unless you have an account with download, and translations softwear, may not be in tis but the pdf is how they work from a maker.

I'm not disagreeing how a TPS works.  I am disagreeing about how the TPS gets damaged by the throttle. Also, a damaged TPS throws up a code in the ecu, and brings on EML.

If you have access to that GM site (which I assume is WebTIS, as thats where all the tech info ends up), the document has an ID (either top left, or anywhere in footer area), its this ID that would prove useful - I can then find it myself on TIS/WebTIS

[Robski]

Id take it to DLK and let him have a look

[rustym95]

the page what im on dose not have a code its just spec of parts and understanding, how they work and faults has no numbers just say update feb 2008. there is 28 pages ranging from ECU faults thats that can be missed i.e potentiometer setting, speed calculateion and on and on. coverd vectra,omega.

[rustym95]

oh and on last page it say, all the infomration in this report refers to faults and ideas from our designes personel regard to improvments and would like to thank them for brining them to our attention.
