Rear height sensor

Hello everyone

Does anyone know the proper part for the rear passenger side wheel height sensor. I had 3 off amazon and it still wont read on the 4x4 screen

Thanks Steve

Hi Steve,
Are you saying car is not recognising the part not communicating with it?

Hello mate

Yeh its not recognising it. On the 4x4 screen its permanently down. Ive done a calibration on it with my computer.

Thanks

Have you tried cleaning the connector blocks with contact cleaner, worked with my off side rear sensor.
If this does not work try a decent make one, I have genuine on the rear and copy front, fronts took ages to settle down.
I still need to calibrate all 4 of them.

Ive also put a new plug on but its still the same. The suspension works fine it just goes down every night but if i disconnect the battery it stays up

You could also try jacking the corner up, do not go too far just get the sensor moving and it may send a signal?

Just read tour last post.
I have similar issue it will not stay at ride height overnight.
Needs calibrating

I have tried that. The last owner had replaced the plug and 1 wire was hanging off so i got a new plug and sensor but not sure if the 3 wires are the right way around

I just copied what the last owner had done

Test the wiring with a multi meter, you should have three wires yellow/brown should have 5volts, yellow/black is earth to ECU so you get 5v between it and yellow/black. You also should have continuity between yellow/black and the metal work of the car. The final wire is yellow/gray, that takes the signal back to ECU. Diagnostic should read voltage seen on yellow/grey in the ECU.

Some are 6 wire depending on what lights are fitted.

OP says 3 wires above

Amazon product

I put one of the above on my 2006 TD6 L322 after same issue, I thought it was a wiring repair I made but it was a duff sensor. Checking the wiring with multi meter pointed to the sensor. I think some of the aftermarket sensors can but put on either side so it is possible to put it on upside down but you should see wheel move the wrong way in the display.

Is that not the rear left wheel?

My 2p worth.
Your screen is seeing it/something. So it is seeing the sensor. Is it seeing it correctly is questionable if you have wires all over the place dangling.
You dont give us the year of the car.

The car will try to self level and that will cause it to deflate it as its "parked in a pothole" from your 4X4 screen pic.

As it will stay up if the battery is disconnected then a leak can be ruled out mostly.

What did the diagnostics show? did it show movement/change?
Does it change on the screen if you move the sensor arm? Which way?

Hi mate it doesn't move at all it just stays the same fully down. I have done a collaboration myself as my obd reader does it but it never comes up with a code for the sensor
