three amigoes,one solution

Finally took my 1.8 1999 3 door freelander to an independant LR specialist. My model is pre OBD2 so the cheap code readers now available are useless. I've read plenty about sensors but never understood or found a good description of what can go wrong. It was diagnosed as faulty sensor on a LR fault reader/computer, despite all the sensors giving identical readings in a resistance test elsewhere earlier. On stripdown and removal of the CV joint with the sensor ring on it, it's easy to see what goes wrong.The cv and the sensor ring are different metals with a friction fit. Moisture and salt off the road eventually penetrate the seals and cause corrosion where the sensor ring is mounted. This causes outward distortion of the ring and the high spots hit the sensor causing it to wear away and eventually bring up the fault lights. The answer is a new cv and sensor which with around three hours labour isn't cheap, especially when you remember there are four wheels and as the car gets older they are all liable to go. Had the sensor ring been machined as part of the cv this would not happen, but is another example of cheapskate engineering/high repair cost of the LR design team. So all those who hope to get away with just replacing the sensor and cleaning out the dirt, beware. Hope this is of use to anyone else with an ageing vehicle and this problem. It's not always the reason, but my mechanic reckons it is in the majority of cases.
