engine oil light on

[kenze]

got a 92 cynos with 5e,starts fine,drives fine,after around 5 mins driving,engine oil light on. turn it off about 15 mins,start again, its off and after 5 mins drive,it would come up again.
anyone can help!!!
before all these happen,just changed cambelt and waterpump.

and i changed the new oil and c if there is any different,but no luck it come up the same result.

is the oil pressure switch/sensor a common problem for 5e?or could be somthing else?

[Mr Revhead]

a faulty oil pressure switch is not uncommon on toyotas

as I replied to this exact same post on NZHonda's ... don't drive it until you're sure, as I've had a car with the same symptom and it was a blocked oil filter, so was pretty major problem.

just changed a oil pressure switch,its going good and no light any more.not sure if i completely fixed the problem.may be still better to check the oil pressure.any suggestion?
