One issue my car has is a "valve stuck" fault..

It says RH front i'm assuming it is RH from the drivers seat?

Or is it when you're looking at the car from the front?

The oddity is..

Using the 2000 scale on my Ohm meter, when the arm gets to this point...

enter image description here

Measuring the pin from the far right of my pic and the middle one, it gets to a point in its travel where it clicks slightly and goes open circuit, If I shift my common lead to the far left pin it continues to read etc 7

From this point it goes open circuit and I have to shift leads.

enter image description here

enter image description here

When on the 20k scale it is quite smooth it ranges from 1.20 to 2.45

On the 2000 scale it is a tad jumpy...

Am i barking up the wrong tree?

H

PS

That is the front right "as you sit in the drivers seat"

I do hope that is the "right front" lol

Left and right is always as sitting in the drivers seat, so yes, you've got that right. If it goes open circuit, that will be the cause of your fault. You'll always see a reading from the two end pins and it won't change. That is measuring the resistance of the track from end to end. From one end to the middle pin, you should see 0 Ohms or very low at one end of the travel and almost the same as the full resistance of the track at the other end.

Ahh cheers.

So i'm assuming the far left pin is one half or the track and the far right pin is the other?

or am I mistaken?

On the 2000 ohm setting it would go open circuit at around half way, if I switched my lead from the far right pin to the far left it would start reading again.

On the 20k Setting it would register 1.20 to 2.45 through it's travel. that is if I kept the common lead on the middle and positive lead on the right pin it doesn't go open circuit on the 20k scale

Hmm.

Hard to explain this!!! lol

one end on the track is 1.25 and the opposite end is 2.45 it doesn't go near 0 at any point

The only time it goes to near 0 is on the 2000k setting on my meter..

See David's tests here https://rangerovers.pub/topic/503-2002-vogue-se-restoration-thread?page=7 (post 131), it appears that the resistance of the track is around 2 kOhms, so that is what you should measure between the end two contacts. Between one of the end ones and the middle, at one end of the travel, you should be seeing a low figure (200 Ohms was quoted in that thread), progressively rising as you move through the travel up to close to the 2 kOhms.

Unless you are getting something like this, it's fubar.

Thanks.

The track in mine reads 1.27 on the 20k scale

would a low resistance be an issue on one of these sensors do you think?

No, it's a potentiometer used as a potential divider. The actual resistance is pretty irrelevant, it's the difference between one reading at one end of the scale and the other.

Ok cheers.

After spending 20mins just fiddling with it..

One thing i've noticed is..

On one end of the scale is reads 1.18 however if I cycle the arm back and forth this changes to 0.69 if it is moved again it reads back to 1.18 kOhms

Odd..

One end of the scale is teetering between 1.18 and 0,69 - The opposite end of the scale is steady at 2.45 kOhms.

Height sensor fiitted.

Didn't even have to calibrate it..

Weird..

Wonder if it works?!
