I have what appears to be a intermittent fault that is causing me concern and wondered whether other forum members have come across it. I have just had a new ABS sensor fitted to the nearside front on my 1999 Jaguar XJ8 3.2L. The sensor was in a bit of a state and the holding nut had sheared off. I was getting the ABS light come on, as well as 'Stability Control Failure' illuminated on the dash. Unfortunately my diagnostic device failed to identify which side it related to, so had to assume it was the nearside. Just spent out over £200 having the old sensor drilled out and removed and a new sensor fitted only to find that the same message appeared on the dash when starting the car from cold. Ugh!!! The offside sensor is new (fitted within the past 18 months) so didn't guess that the problem was on this side.
The issue with the error messages is that once the car is started and driven, as a result of stopping the car, turning off the ignition then after a few seconds restart the car, the message goes away and stays away until the car is stopped for a longer periods of time and then it comes back again. It has been suggested a new ABS harness is needed, but at nearly £300 including new part and fitting, I don't want to go down this road, only to find it doesn't resolve the problem. Has anyone else experienced this?

 

it’s the module, usually throws a C1095

take it to a shop that’s competent with these cars

 

I have never had to replace a speed sensor unless a wheel bearing failed and physically damaged the sensor.

I replace the link harnesses ALL THE TIME. (that is what fails if the DTC is for a sensor circuit)

Checking the DTCs is the most efficient way to find the problem but there are people that refuse diagnosis and simply want to replace parts until the car is fixed.

 

Had an software upgrade to my diagnostic reader and now it says C1145 'Wheel speed front right input circuit failure'. Would that be the harness?

 

I replace the link harnesses all the time. (see post #3)

 

Got S/H harness on order. Hoping this will cure the problem.

 

If in doubt, you can swap the link harnesses side-to-side to verify that the fault followed the harness and NOT the sensor?
