Yes. If the sensor is only momentarily off line the ABS light will come on and go off again after a short period. If the fault condition remains for a longer period of time the ABS shuts down and the brake warning light comes on. When this is on you have NO ABS. Turning the key to the "START" position will reset it, the lockout will prevent the starter from operating while the engine is running.
Sounds like you have an intermittently open circuit wheel sensor, probably one of the fronts.
As Derek says, front wheels most likely. The front nearside (kirbside) is the most common culprit, as this wheel receives the most abuse. If cleaning the ABS sensor doesn't prevent the fault occuring, a garage with suitable diagnostic equipment can interogate the ECU fault codes to determine which wheel sensor is causing the problem.
In my case an ABS light fault was due to a poor connection on the main valve. ABS fault diagnostics can be done with two wires and a switch. For details check out an excellent US site http://18.104.22.168/ for which I owe thanks to Paul D, thanks Paul. This site has real circuit diagrams unlike the Haynes manual "circuits" which have little infomation.
