Posted by Liam Clohessy on April 28, 2011, 5:40 pm

Year of Manufacture *: 2001

ABS light on. Read fault and it said left hand rear sensor, no communication. Checked sensor and connections and could see no fault. No speed reading when spun manually on left rear. Had reading on all other wheels. Fitted new hub with abs sensor attached to left rear and still same problem. Checked onnections back as far as abs pump. Looks like abs pump. Has anyone oome cross similar problem with this model

Hi Liam

I have had a problem with cheaper aftermarket bearings, no signal after fitting, plug the old one in and light goes out

The problem was the connector on the new aftermarket bearing, with small pliers pull out the seal inside the connector and then try connecting again, it just allows the connector to go in another mm and make a connection

Hi Liam, was it definately an inductive speed sensor, or was it an active snesor, also called a hall sensor?

Hi Liam,
Disconnect both rear sensors and swap the left sensor to the right side harness and vice-versa, using lengths of wire, then look in live data and spin the wheels.

this will confirm the new sensor at least.

after that its either wiring or the ECU.

Regards Mark.

PS. remember that some active systems turn off the supply to the sensor if a fault is detected

Modern cars, Its all wizardry and witchcraft
