Troubleshooting: Check that the speed sensor and the tone wheel are installed. If they are not, install
them. If they are, check the speed sensor retainer. If it is not OK, restore it. If it is, check if the tone
wheel has the correct number of teeth or if it is dirty, deformed or wrongly fixed. If it is not OK, replace
the tone wheel and if it is OK, replace the speed sensor.
5D95 excessive speed measured: Faulty sensor or tone wheel, or tone wheel with wrong number of
teeth or wrong tyre size.
Troubleshooting: Check that the speed sensor and the tone wheel are installed. If they are not, install
them. If they are, check the speed sensor retainer. If it is not OK, restore it. If it is, check if the tone
