Most of these models have 2 oil lights.The red one is oil pressure,if flashing or on when engine is running,it is usually serious.check oil level,but usually caused by blocked pickup screen(a common toyota fault) when services aren't done.The orange oil light is tripped by an oil level sensor on the side of the sump when the oil level is low.If the oil level is ok,note this is a common fault especially if oil changes have been missed,and/or a petrol engine oil used and sludge builds up,sometimes using an additive for flushing prior to oil change can help,but may not work on 1st oil change.

Hi this could be a couple of faults, first obvious one oil level, have you checked to see if you have enough oil in the engine, second, oil pressure sender unit or sensor, this could be faulty if you have enough oil,thirdly, oil pump starting to give up, normally you can hear a slight droning from the front of the engine, and lastly ( witch is the worse scenario ) big ends starting to wear, normally you will hear a knocking noise when you start the vehicle dependent on how worn they are, badly worn loud knocking especially under load, slight ware, you hear the knocking for a few minutes then dies away when it gets hot, this is impending doom and should be looked at straight away or engine could seize...hope this helps

SOURCE: i have a 19991 toyota previa. the oil level light

If the light is flashing there could be problems with the electrical wiring. The easy places to check are at the bottom of the oil reservoir (pass. side under the hood) and at the driver side of the oil pan under the vehicle where the wires plug into the sensor. If this doesn't resolve the problem then it isn't easy, and testing the circuit will have to be done by someone who knows their electrical "stuff." Even the pump motor for the reservoir could be out.

If the Oil Level Sensor light stays on and you have already checked to make sure the oil level read on the dipstick under the driver side seat engine compartment is reading adequate, then you have a sticking oil level sensor float. Replacing the oil level sensor is easy, but extremely expensive ($485 in 2012). You can try to clean the plastic spool that the float slides on, but the problem is usually that it has swollen or expanded (likely from heat in the oil). One could try to sand it down but this would be difficult. I have made a new part out of nylon 6/6 on my lathe and replaced the plastic spool so far with excellent results. I'm considering selling it as an aftermarket part when I see if mine works. It would be a lot less than $485 dollars from Toyota. Or possibly have people send it to me and I'll repair the sensor myself.

I have a 1993 Toyota Previa. It has been leaking oil for the last few days. I have difficulty turning the wheel and at the same time it makes a wealing noise. I checked my engine, brake, and power steering...


No, this is a power steering issue. Are you certain the power steering fluid level is correct? The squeeling noise is caused by air in the power steering pump. The leak must be repaiored, usually by replacing the pump, unless it is just a leak in the reservoir.

Oil light stay on.


The oil level sensor was either damaged, or it has failed. In any case, the oiul level sensor needs to be replaced.
Common problem.

The graciousness of a FixYa rating for my assitance would be appreciated. Thanks in advance.

When you say "warning light is on", I assume you are not talking about the oil pressure gauge...
If not, here is your solution:
What you have is a very common problem: The oil LEVEL sensor has failed. Previas have 2 sensors; pressure & level of the oil in the pan...What you need to do is replace it, Toyota part number : 89491-28030.
BUT...This part is $380.45. Not cheap; Sorry but true.

Warning light


the red light indicates low oil pressure, check your oil and add as necessary, if it still comes on you have some type of restriction in an oil passage somewhere. the reason it only comes on when turning is because when turning the fluid level shifts in the oil pan and if it is low it is moving past the pick-up tubeand you only pumping air
