Check the battery connections to be sure the terminals are not cracked or corroded, then check the battery it may have a low or dead battery or a shorted cell, try to jump start if it starts ok then replace the battery

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

There are three temperature sensors on a 95 Previa engine. They are located on the left front side of the engine. The lower one is somwhat accessable from under the vehicle but access to the other two will require removal of the passenger seat and the access cover under the seat.

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.

The short will be in the fuel pump.

It could be a faulty oil sending unit, but it would be advisable to have the oil preasure checked with a mechanical guage to determine if it is a sending unit or low oil preasure. Oil preasure low enough to allow the light to come on is low enough to possibly cause major engine damage.

Sounds like throttle cable is stuck.

Have the fuel pressure tested. Also do you have a Check Engine light on?

The alarm might be setting to sensitve motions detecting mode,this setting,if u come close to the car or slicely taps or touch it the alarm will go off.This setting it is not good for the car as the motions detection sensors over time will get old and will go off at anything causes some presure even slice wind just past by the car.Take ur car to the alarm tech. check it out for the motions detection sensors again change to mormal setting not sensitve mode this setting mode it actually the best,because the normal setting the door have to open before the alarm will go off.Or the alarm tech have do a replacing a new alarm unit it self,because the detection motion sensors can not do a readjustment or resetting the setting any more.

check bulbs if there okay check fuses

it's a 4 liter oil
