Low oil pressure light

[Seanocaoimh]

Back again for more advice. The oil pressure light comes on at idle, but goes off again when I in crease the rpm to 2000.
 Any advice ( relevant), appreciated.

1. check your oil level (@cause it's easy to do)
2. check your oil pressure sensor.

3. check oil pressure w/mechanical gauge: 49 psi @ 5K RPM (oil @ 80*C)

thanks for the prompt reply lads, would ye think it would be ok to drive if I kept the revs up? why would the revs have a bearing on it and I assume the oil pressure valve is the sensor behind the head, and when removed the pressure  tester would screw in instead. Any idea where I could pick up the appropriate tester

Correct -- on top of the crankcase, behind the cylinders, under the throttle bodies.

An automotive parts store should either have one or can order one -- an adapter may be nec. (diff. threads/etc)?

Great stuff! Any ideas about the idle speed illumination of oil light ? Only comes on when engine is warmed up and stopped at traffic lights / slow moving traffic. Should I not ride the bike until I have this problem sorted.

First, are you sure of the age/condition of the oil, as in, it has definately been changed in line with the service schedule (i.e about 12 months/6k miles). If the oil is old, dirty and worn it will have thinned out which could give low idle oil pressure when hot. If in doubt renew it.

I (personally) would (if happy about oil condition) go straight to eliminating the Oil Pressure Switch for the sake of £25 from Triumph before spending that amount or more on a pressure gauge .... that would be my next step if the new switch didn't clear the 'idle oil light'.

Raising the 'idle speed' definately isn't the answer IMO.

Was the oil filter changed at your last service?
What is your bikes mileage, although oil pumps don't usually give up the ghost on modern triumphs.

I am just thinking that at low revs the oil circulating system may not be efficient.

I do bemoan the fact that oil and temperature gauges are no longer fitted to vehicles these days. They were a great early warning system.

I have everything stripped back and the low oil pressure sensor wire removed from the sensor. How do I test it to see if it works properly.as I say the oil light comes on at low rpm.

I would think that the resistance @0 psi should be 10 ohms - that's all you can check with it off really.

 Can you clarify what the condition of the oil and filter is?
