G'day Folks,

I get the feeling I'm half way up **** creek with out a paddle!

Throttle valve position sensor is bust. It is meant to give a signal of less than one ohm when it is either in the closed or open (WOT) position. It doesn't - it gives more than 2 ohms and this generates an ECU error signal.

The switch has part number 126 540 59 45 on it but this is NLA

The other numbers (LK <= seems to be Hella) 04 8062 67 and the VDO number 90 003 081 also give me no joy.

The diameter of the throttle housing is 60mm. I get the impression the majority of the second hand throttle housing with the switch on the second hand market are of a larger diameter which I assume would mean they won't fit my inlet manifold...

...besides all that is wrong with the mechanism is the switch.

Has anyone got any alternative numbers for this switch?

The number starting with a 126 gives me the impression it was used with larger engines in the W126 s-class series (although that isn't always the case).
