Thread: Ebay abs wheel sensors

If the stationary output of the sensor is the same with the others and the reading becomes erratic whie driving in most cases the problem is caused by play in the reluctor ring so a new sensor is not the cure but you need a new hub especially if the fault code is air gap related

^ This.
D2 owners must consider the kms now vs posts and discussions on sensors when the D2 was a much newer vehicle.
Majority of D2 are at kms/age now where electrical gremlins are long sorted and wheel bearings are approaching “life” and should be considered in diagnostic trouble shooting
1.9 to 2.2 ohms is a recollection of the serviceable range of sensors. RAVE should be checked.

Those are stationary voltages, actually 2.1 - 2.4V is the good range, the resistance of a sensor should be between 950 - 1100 ohm

The LR wiring back to the SLABS can be problematic too. Mine was defective somewhere even tho I could not see any damage to it and the connectors were all good. Once replaced with a long lead sensor. .no more probs.

May have got damaged at the wheel end or where it comes up from the chassis rail to the engine bay eg by a stick.

Stationary output? Is this the resistance? or will a Nanocom tell me?

Nanocom in the SLABS inputs menu which shows the sensor's voltage outputs while the vehicle is not moving and if then they are all ok what comes after is due to play in the reluctor ring so new hub needed... though if you spent some decent money on a nanocom at least download the user guides and read them cos it's all there

Sadly the data looks the same or similar across all four wheels. The variance btween the average of the other three wheels and the Front RHS is 0.01 stationary and moving. Voltage is 2.17. the other variance max is 0.63, this is 1.8 stationary. Infact the Front RHS data when it is the lowest or the highest is very close to the next data point. Most of the front RHS data points are not the highest or the lowest. I drove in the supermarket car park in low range. Looks like I need a new hub!!

Mmm..been there new hub new short lead sensor new amigos. .twas the wiring back to the SLABS. ..nanocom voltages etc all read fine...long lead sensor is much cheaper than a new gen hub!

You can't rule out intermittent faults eg that arise when driving. Stationary mine all read fine....

Your choice tho☺
