Replaced both rear height sensors and rewired new plugs. Suspension still on stops and won't raise ,above fault registered on icarsoft scanner ,cleared fault but returns after driving short distance, any pointers??

you havnt by chance put the height sensors in back to front??

Don't think so as both plugs are facing upward, also if I turned one over the plug looks like it would foul on the chassis

i did a forum search and that was a possible cause the another was broken wiring..

I've searched also and can't come up with a definitive answer

Just read these values from icarsoft 930, front right voltage 2.85v height 0.038, front left voltage 41.86v, height 0.053
Rear right voltage 4.77v height 0.00 rear left voltage 0.85v height 1.404 height shown in inches
On ABS scan 0x005A temp system deactivation,
0x008A air suspension system CAN error message failed to clear DTC'S
front raises and lowers off switch but rear not moving at all,
Replaced both sensors and rewired new plugs rear was on its arse before changing parts.
Anyone help please!!!!

I have the same problem replaced the two rear sensors and now will raise front fine but the rear gos up but not level
How can the sensors be wrong way up they only fit one way on the chassis can you get new wire loom or a repair kit for them as I am not sure if mine are. All ok.
Like you you clear the fault then mile down the road its back in inactive?

You can get the plugs with wire tails from this site, look on shop on the home page that's where I got mine listed under connectors and adapters

I had this on my l322 you could clear fault then it would be back a mile down the road.
I changed sensors and fitted a wiring repair kit as I thought there may be a break, in the end I had to bite the built and take it to the garage.
It was found to be one of the brackets that holds the sensor in place at the rear was bent and causing the fault £6.35 bracket they also soldered my joints instead of the crimped connectors.
worth checking.

My old range rover had a few height issues and I ended up having 4 new sensors although only 2 were dead, I was told that they work within a set tolerence of one and other, so if they all wear at the same rate and voltages shift etc they stay within that tolereance, introduce a brand new sensor and it then operates outside of the tolereance and the car doesn't like it.

i'm not 100% sure on the info but doing all 4 sensors fixed it. Current

My car is practically off-road most of the time or at least that’s the state of the roads here (BVI)

I have the same issues as everyone else I guess, ABS Error shows AS CAN error and the AS errors flip between Static Res or the Articulation error. These require clearing periodically, but rarely when on good roads.
I've used a service kit on the pump $35 and works great. And bought 4 OEM Height Sensors which I have yet to fit.

Some frustrating results below, but no-one mentioned (hope I have this right) that, the new sensors have to be calibrated measuring the distance between the hub center and bottom of wheel arch rim, directly above.
The heights seen in the diags can be ignored and used only to see the up or downward movement scale when adjusting (repeatedly checking the tape measure until all correct). Apparently once set using the tape measure to get all the heights right, this is saved as the calibration and will now articulate the resultant feedback. The diags will show heights all slightly different and can be ignored.

I’m going to do mine in the near future, using my Autel DS708, a tape measure and the settings below (thx Joe90). If anyone thinks I’m talking rubbish feel free to set me straight.
