1995 Toyota Previa - Page 2 - Answered Questions & Fixed issues

The whining noise at start up is either the power steering pump (possibly low fluid, or faulty pump bearing), or possibly a belt on the engine. As for the knocking sound, that is hard to diagnose without actually hearing it, but based on the fact that you are hearing a whining sound at start up, which is indicative of a loose belt, I would start at the belt tensioner and make sure that it is applying the correct amount of pressure on the belts. If the belt tensioner is faulty, it can make a knocking sound. If that is not the issue, then it could simply be the lifters. With engine run time/miles on the engine, internal engine components, such as lifters, valves, bearings and any moving part, deteriorate from friction wear and heat.They have a tendency to make a knocking/rattling sound when they are building up pressure. When they build sufficient pressure, or the engine reaches operating temperature, this sound/noise will dissipate and become nonexistent. This can be remedied by changing the oil, and possibly the weight of the oil (5w30, 10w40, 20w50) depending on your driving habits , or conditions (Highway v/s City/Stop&Go, or short trips under 30 miles)I hope that you have found this information to be useful, and if I can be of any further assistance, please let me know. Thank you for using fixya!

I have toyota emina,diesel engine, i change oil every reaching 5000 kilomters on guage, with 6 liters diesel engine oil.

Replace the distributor. That should take care of it. All the best

Aftermarket alarm??? Have it taken out and the vehicle put back to stock. Once those types of alarms get old they tend to fail

On for each valveYou have to know how many cylinders& valves per cylinder--Google itYou can't fix the noise anyway, withouttaking the engine apartThe motor is probably worn out, if it is in theresince 1995

what is relay 056700-8570 for acura integra

HiRaise and support the vehicle Remove the rear shock absorberPush down on the lower control arm enough to allow the coil spring to slide out.Remove the upper and lower insulators and check them to see if they need replacing.I hope this helpsCheers

hi the positive battery connection is from the starter motor and the negative connection gos to the engine or body of the vancheers

HiThe black wire will be connected to the body or engine of the van and the red or positive wire is connected to your starter motor.You can also use a 12 volt battery light to check the negative or positive wires.You take the 12 volt battery light and place the negative black wire clip to an earth on the vehicle, then when you touch the tip of the 12 volt battery light onto a positive wire the light will light up.Then you will know which wires are negative or positive sometimes the key has to be on for some wires to work.Cheers

Armrests are part of door panel. Usually has holding screw in handle itself then pop panel off as one piece.

1. check your battery.
2. check your connection to the starter
3. check your ignition key.
4. check your relay, etc

do you mean the starter wont turn the engine over

Have your battery tested to start the fact that the radio and lights work are not an indicator that the battery is good. if in fact battery is good and you hear a click and nothing else then make sure you got power at starter from ignition switch and power going to the actual starter motor while some one holds the key in the crank position. Do this safely. the starter should have power on the B+ terminalwhich comes directly from the battery. It also gets power when in the crank position to engage the solenoid in the Igniton terminal when engaged the power from B+ is tranfer to the the starter motor which in turn turns the engine if this isnt happening for you replace the starter

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

if it works jumping it then the starter is fine. check fusible links to see if one is blown. check all contacts, engine grounds too, for corrosion and clean if necessary.

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.

Sounds like throttle cable is stuck.
