Wheel sensor failures

[muppix]

You'll need an OBD tool in order to find out which sensor it is, or you can just replace them all - the others will probably fail within months of each other anyway. Highly unlikely that it was damaged from removing the wheel, the sensor is squirrelled away at the back of the hub.

On what basis do you advance that hypothesis?

 

Most failures are caused by external influences, rust on the trigger ring clouting the sensor or a kerbing incident bith of which can fracture the sintered magnet inside making an intermittent and eventually permanent fault, mine started after a kerbing.

 

Its a very simple and very robust sensor, there are no components with a lifespan, if a magnet becomes fractured there is no reason that any of the others will have the same fate except a driver frequently clipping a kerb or mechanic beating the hell out of another hub with a hammer.

 

£170 - £180 to replace, £90 to buy, mine cost €6 or €7 including delivery from China, at that price I bought several in case they did not last but the one I replaced has been every bit as reliable as the OE ones.

Took car for MoT (UK) and service, during which two tyres were replaced.  On getting the car back, car gave an 'Error Tyre Pressure Loss Indicator' warning, though initially it was a tyre pressure issue, (pressures checked then reset), only for the warning to reappear along with the following in quick succession

 

Error Start Stop System

Error Cornering Light (AFS)

Error ABS/stabilisation control (ESC)

Error Hill Hold Assist

Front Assist not available

 

Now, assume it's the sensor failure that others are discussing above, however questions are:

 

1.  Any idea which wheel sensor it would be and

2.  How likely is it that the sensor was damaged by the garage when the wheels were taken off

 

 

 

You did not say that you reset the TPMS after resetting the pressures, if not done then it absolutely would trigger another warning and there is no reason to assume that a sensor has failed, all of the above systems cannot work unless the TPMS system is functioning and the new tyre pressures have been validated.

Yup, TPMS reset
