Oil light intermittent, fades, sometimes steady

Oil light just started yesterday, fades in and out, checked oil, okay

Check the connection where the wire plugs onto the sender unit. If it's loose, or the wire shorts out to the body, it might flicker. If this isn't the problem, unscrew the sender unit and check your oil pressure using an oil pressure gauge screwed into the same hole. The pressure should be above 40 psi if my mind serves me correct. If it's too low you'll have to replace or check the oil pump. Did you replace the oil filter and oil recently? If the filter is blocked or the oil is old it might also cause the pressure to drop too low.

My oil light on a 1999 nissan sentra is coming on. I changed the oil and oil filter about a week ago before light came on. What could be the issue?


Have you observed any leaks or loss of oil in your engine?


Though this may not be the case, my daily driver suddenly started flashing the oil light after a couple days. I saw some oil spots in the garage a few days before finding out that I was in for a very costly repair...

The rear oil seal, in between the crankshaft and the flywheel was dislodged and eventually needed replacing.

Hope this is not the case for you, and it is a simple fix for you by checking if the oil filter is properly seated and there are no leaks. Pull out your oil dipstick and ensure that there is enough oil in the crank case to flow around the engine during operation.

Many times the oil light coming on is an indicator of inadequate oil pressure, and should never be dismissed as a simple error in the system, regardless of having a proper lube job done recently.

Hope this helps.

just look for the blackened/burned pin on the rear light plastic connector and sand it down to re-establish a good electrical connection and save yourself $800 big ones on replacing the multiswitch.

Check engine light on after oil change three days ago


Your "check engine" light is an emission light. Oil is fine. You have to find the code to check whats wrong. Usually an engine light is just a tiny problem, but in other cases it could be anything from a sensor, to a bad cat converter. With a check engine light on a vehicle will not pass smog tests. You can turn it off by unhooking your pos side to the battery for about 3 min. Then you will have to drive it 30 miles non stop for the computer to put the code back in and the light will come back on

1985 Ford Crown Vic engine when hot outside last 2 years would take time to start as I waited to re-try until it did. Lately has to have a jump and starts right away. Shop replaced: battery, serpentine...


It sounds like you have the wrong thermostat installed in your car. You need to get the water to the block quicker then what it's doing now. Always check oil every time before driving. This is a must on older cars. Some Mechanics differ, but in the long run it will pay off. An oil spot beneith the car might be bolts that need to be tighten on the oil pan, of you may have a bad oil sending unit. Also ehck power steering pump fluid level and make sure there is not a leak there.

1989 honda accord lxi fi oil light


Sounds like there is an oil pressure problem. Now this can be due to several factors. 1. low oil level in car
2. bad oil pump
3.bad oil pressure switch /sending unit
4. last but not least check oil filter and make sure its not clogged.
worn engine main/connecting rod bearings.
have pressure checked with a manual guage at oil pressure switch for the correct pressure. If that's good then the switch is bad and problem solved.
if it low then you will have to check pump and bearings. Contact if you need more help and thanks for using FIX YA
