Marks 110 Posted March 20, 2011 Share Posted March 20, 2011 Oil warning light came on the other day for first time in 10 years (except when ignition first turned on). Saw it flicker a few times and then it stayed on. When I stopped and restarted it was off again but reappeared after 5 mins. Engine running fine no oil loss or strange noises. Have tested the oil pressure by removing switch and screwing in pressure gauge. Getting a reading between 25 and 55psi (manufacturers recommendation) so pretty sure its either the switch or wiring. Just wondered if there's an easy way to test the wiring before I splash out on a new genuine switch. Cheers Mark Quote Link to comment Share on other sites More sharing options...
mmgemini Posted March 20, 2011 Share Posted March 20, 2011 Oil pressure switches are often unreliable. Put a new one in for the cost and peace of mind Quote Link to comment Share on other sites More sharing options...
western Posted March 20, 2011 Share Posted March 20, 2011 check your idle RPM too, needs to be 750 to 800rpm, if to low the oil light will flicker. a new switch should cure your current problem, to test the wire just do a continuity check with a multimeter or test bulb.

There is continuity between the spade connector on the switch to the the warning light on dash. Guess its new switch then.
