NO SPEEDO, MIL, ABS, TC LIGHT ON CODE 502

#1
Hi,
i have a astra G 2001 2.2 bertone Z22SE
when i bought the car it had an intermitent fault being,
speedo would work then stop also the odometer when this happened
the MIL, ABS, TC lights would come on happened the previous owner
said he had replaced the speed sensor but did not clear the faults he mentioned he
suspected a bad connection with the abs pump connector block
but now the fault are constant,
has anyone had any similar problems or knows how to go about eliminating the faults
on the scanner the code is P0502 - Vehicle Speed Sensor Low Input
help would greatly be appreciated

if you can safely lift the front whheels up you could put a multi meter across the sensor and see what the signal is doing in relation to wheel speed? not sure other than that tho really or what you should see.

Check the condition of the teeth on the ABS ring on the CV joint. Its a common fault on Vauxhalls. The ring cracks with age and corrodes giving an erratic speed reading and putting the ABS light on.
